The language on this page is so extremely unclear that it makes the whole article useless. It contradicts itself internally and with relation to references because of the unclear language, overuse of scientific terms and frequent use of double negatives. It will be highly appreciated if someone with knowledge of the subject will simplify the wording. I came to this page seeking clarification of Cortisol and it's relationship to Stress and Inflammation and left more confused than before.Jpvosloo (talk) 19:38, 2 August 2009 (UTC) hola que hace Yes, please.

Should merge with hydrocortisone?

There is another less developed page entitled hydrocortisone. Obviously it deals with the same substance. Perhaps that entry should be merged with this one? KBi 03:25, 3 May 2005 (UTC)

I suppose they could be merged, as hydrocortisone is the synthetic cousin of cortisol (as far as I know)...

According to Guyton, Hall: Textbook of Medical Physiology (p.875), these are just two names for the same substance. --Eleassar777 21:59, 29 May 2005 (UTC)

I looked up online sources such as the NIH and they say that hydrocortisone is the synthetic version of cortisone and that is is similar, but apparently not exactly, the same. Also, some people are allergic to hydrocortisone, though that article is about the skin and perhaps you can be allergic to natural cortisone on the skin or elsewhere. I would keep the article together, as they've apparently been merged now, and simply make sure that the distinction between them is made. Kjkolb 16:46, Jun 14, 2005 (UTC)

Cortisol and Hydrocortisone are absolutely the exact same molecule. The only distinction is the sphere of usage of the term. Cortisol is uniformly used in biochemistry. Hydrocortisone is the term used in pharmacology.

If you search the PubMed Substance database, you'll find 56 entries (because this is a meta-database from different sources), all for the same compound, all listing cortisol and hydrocortisone among the MANY, MANY synonyms. (A historically important synonym is Kendall's Compound F).

However, you are correct that hydrocortisone and cortisone are similar, but not the same! But this is not about cortisone, it's about cortisol/hydrocortisone!

Cortisol/hydrocortisone and cortisone both occur in the body. Cortisone itself is not particularly active, if at all, but they are interconverted by the enzyme 11-beta deoxysteroid dehydrogenase, types 1 and 2 (for each direction). See the Metabolism section of this article. Historically, cortisone was used theraputically, but this has largely been replaced with hydrocortisone or the synthetics.

The article for Hydrocortisone now redirects to Cortisol, as it should. The Cortisone article is separate, and should remain so.

This article incorrectly indicates that "Hydrocortisone is the chemical form of cortisol used for oral administration or intravenous injection". I'll correct this to:

Hydrocortisone is the pharmaceutical term for cortisol used for oral administration, intravenous injection, or topical application.

Bob Kerns (talk) 16:36, 6 December 2008 (UTC)

I realise I risk challenging a huge body of respected expertise here, in addition to which I'm no biochemist and this question comes from personal experience, but I think it's important enough an issue to raise in the hope that someone more educated in these matters can comment. If hydrocortisone, produced outside the body, and naturally occurring cortisol, produced in the body, are indeed interchangeable, why should someone (i.e. me in this case) suffer fairly serious, very characteristic, allergic symptoms to the former - administered transdermally and at a physiological dose - and have no such reactions to animal-derived cortisol extracts? To clarify; when I say very characteristic, I mean that it is a set of symptoms which ONLY occur on exposure to synthetic steroid medications; when I say animal-derived cortisol extracts, I am not talking about a weak supplement formulation not worthy of the name, but one which restores my very low cortisol levels to normal. Could it not be that the chemical (hydrocortisone) in isolation from its biological context is not treated by the body in the same way as that which is naturally produced [by a body]? Glaciare (talk) 11:00, 1 August 2010 (UTC)

(I'd forgotten about writing the previous comment...) To answer your question:

I cannot quite fathom the concentration of hydrocortisone and area of application that would be required to restore very low cortisol levels to normal. I'm sure it would be substantial, as we are talking about transdermal adsorption of perhaps 10-15 mg of material. For reference, a $5{\tfrac {mg}{day}}$ Androderm patch has $15cm^{2}$ of area, with $24.5mg$ of testosterone in an alcohol-based gel. The total patch is $44cm^{2}$ in area. Furthermore, this is a higly non-physiologic mechanism for delivery of hydrocortisone, as it is far too slow to mimic the diurnal variation in blood levels. Instead, you are subjecting the skin, locally, to concentrations far beyond physiological levels, which over the long run, may be quite damaging to the skin, due to collagen loss, even if you rotate it among different sites. This is why over-the-counter hydrocortisone preparations are limited to 1% concentration. So you would need a very large amount of preparation, over a very large surface area, rotated from site to site, to successfully treat the condition and avoid serious problems with the skin.

So concentrating it at the skin as you are doing is indeed going to be treated by the body in a very different way, than the much more dilute and uniform distribution resulting from normal adrenal adsorption.

As to why the difference: whatever you are applying to your skin is not the white crystalline powder that is pure hydrocortisone. I believe all current commercial hydrocortisone preparations are derived from plant sterols. Trace proteins from the plant origins or the chemicals used in the intermediate steps from this process could potentially be related to your symptoms. However, whatever your hydrocortisone is mixed with to make whatever creme or other formulation you are applying is a much more likely candidate, as there is a large quantity of material, compared to traces. Both your synthetic and animal-derived versions will have these "filler" materials, which are an important part of the drug delivery, but they will be different. Neither one is at all similar to the biological context in which cortisol is found in your body, where it is mostly circulating in the bloodstream, mostly bound to various proteins (Cortisol Binding Globulin and Albumin).

If your preparation is being prepared by a compounding pharmacy, they may be starting with a preparation intended for oral use, rather than dermal.

A much more natural way to get it into your system is orally, and this is what nearly every person with Addisons does in this day and age. This puts it into the bloodstream fairly quickly, which is important to match the high levels in the early morning. You can divide the dosage, with larger amounts in the AM, to more closely mimic the natural pulses produced by the body.

I know of a couple cases where people used insulin pumps to deliver hydrocortisone succinate subcutaneously in a pattern throughout the day.

But I hope your diagnosis of "very low cortisol" levels is based on actual stimulation testing, and not a single cortisol blood draw, which can be highly misleading, because the levels vary so much throughout the day. Use of hydrocortisone or similar steroids can actually suppress the body's cortisol production. Please do not change your therapy without competent medical advice, preferably from an endocrinologist, as the consequences of a lack of cortisol are quite serious, whether as a primary problem, or as a result of prior use of hydrocortisone. Also consider that if your body is not producing cortisol, it may not be producing aldosterone, which is also a serious problem.

Finally, I want to note that asking medical advice on the talk pages of Wikipedia is not a very good approach. There are forums dedicated to the topic which will give you much better and broader feedback, but your best input is a doctor with some real expertise in this area -- an endocrinologist. I do not believe any competent endocrinologist would have you addressing low cortisol via transdermal treatment. Bob Kerns (talk) 08:54, 25 April 2011 (UTC)

Hi Bob, and thanks for your reply. Firstly, my motive for posting this was a genuine curiosity about these two substances being regarded as interchangeable. I do have medical supervision (I do have clinically-low cortisol levels throughout the day) and - something I worded misleadingly in my first paragraph - I do take oral cortisol. My doctor did not try me with oral synthetic hydrocortisone because I have had such extreme reactions to all synthetic steroid medications - administered by any means - ranging from prolonged and 'mobile' grand urticaria with fever to systemic swelling. The hydrocortisone cream I used (once, some years ago, for eczema) produced the same grand urticaria - i.e. it moved all over my body for several weeks after cessation - so the chances of it being another excipient are minimal, I would say (nothing but synthetic steroid medication has ever caused this kind of reaction). I may be an odd case, but I wonder if any similar ones have been recorded in the literature...? Glaciare (talk) 14:47, 7 May 2011 (UTC)

TV ads

what about the tv ads for fat people for otc meds that reduce cortisol. anyone know about info on how they do/dont work and why, & add it to the article - anonym420

I live in a country without direct-to-consumer advertising, so we are spared this. Bottom line: they don't work. It's based on the premise that fat people have hypercortisolism, but this is not so, unless they have Cushing's disease (a rare condition compared to obesity). If these drugs worked, they'd be causing Addison's disease, which is more dangerous than Cushing's in the short term (hypotension and hypoglycemia being phenomena one would expect).

error ?

hello, i am not an expert, but after browsing several related topic on insulin, is there an error on the following paragraph (marked by asterisks), shouldn't the marked word be decreased instead of increased? :

"In normal release, cortisol has widespread actions which help restore homeostasis after stress. It acts as a physiological antagonist to insulin by promoting breakdown of carbohydrates, lipids, and proteins and so mobilizing energy reserves. This leads to increased blood glucose concentrations and *increased* glycogen formation in the liver (Freeman, 2002)."

Cortisol does indeed cause increased gluconeogenesis and increased glycogenesis at the liver. In other words, it stimulates the liver to make glucose, and make glycogen, which is the storage form of glucose. However, this is not counterproductive. The idea is to increase glucose now (primarily for neuron survival), and store some in case of continued or additional stresses. It also has an anti-insulin action at muscle, adipose, and other insulin-sensitive tissues where it prohibits glucose uptake. Just2seeusmile52 (talk) 00:44, 18 April 2010 (UTC)

It sounds odd, but most of what I found on Google seems to support the present version. JFW | T@lk 16:41, 20 November 2005 (UTC)

You are right on the logic side but the fact is cortisol is not part of glycogen regulation. I was wondering the same thing until I saw how it goes: If there is increased blood glucose there would be increased glycogen formation. It goes well with the fact that it promotes after stress homeostasis(the epinephrine burst that decreased liver glycogen would be gone).

There are 4 major regulator of glycogen metabolism: insulin and then glucagon, epinephrine and norepinephrine; the first one resulting in increased stockage and the others in increased degradation. Stress normally induced degradation and cortisol is a stress hormone as is adrenaline(epinephrine) but it seems it is more post stress and so that could explain it.

cortisol does not increase glycogen formation and this statement needs to be removed.

Cortisol promotes glycogen break down in muscle and glycogen synthesis in liver -- Kaplan physiology 2006. This is how it works: Cortisol stimulates processes such as glycogenolysis in muscles and gluconeogenesis, which increase blood sugar level. High blood sugar(=glucose) level causes beta cells of pancreas to release insulin. This insulin causes the liver to start synthesizing glycogen from the circulating glucose. Hope this helps. PS: Insulin also causes glycogen synthesis in muscles, but i guess this is offset by glycogen breakdown due to cortisol.Evox777 (talk) 03:22, 10 December 2009 (UTC)

Does Corticol cause Obesity?

is it true the hearing increased cortisol translates into obesity?

Yes, see Cushing's syndrome. JFW | T@lk 10:24, 29 November 2005 (UTC)

pregnenolone

By my understanding, cortisol is synthesized from pregnenolone rather than progesterone. The steps in the cortisol synthetic pathway from cholesterol are: Cholesterol -> pregnenolone -> 17-OH pregnenolone -> 17-OH progesterone -> 11-deoxycortisol -> cortisol.

correction

I have found an alternatively described pathway that does show that cortisol can be synthesized via a progesterone intermediate. However, progesterone is first synthesized from pregnenolone, still making pregnenolone the original comitting precursor molecule for steroid hormone synthesis.

Side effects of topical application of cortisol cream

Are there any? I've found its immune-system repression is great for fighting psoriasis but I wonder if there are any long-term effects from repeated use on the same area of skin. 00:14, 5 August 2006 (UTC)

Stretch marks (I developed some after a few uses of 0,1% Locoid only), thinning skin, permanent aged apprearance. With larger areas you also get large absorption and systemic effects. It's really just an emergency medication 82.131.63.11 (talk) 19:56, 6 June 2008 (UTC)

This is the tip of the iceberg. Of course, it depends on the dose and on your baseline levels of cortisol, but cushingoid symptoms (as described above) are certainly a risk. ACTH and endogenous cortisol suppression would also follow; after all, if you're putting it on your skin, why should your body make its own? Rapid discontinuation of topical hydrocortisone would then lead to Addison's Disease - like symptoms. Eventually one's pituitary gland would sense the change and correct the disruption in the feedback loop, but this would take some time.

Cleanup required

I think the Physiology section is awfully messy/noisy, and in the Pharmacology section, is it strictly necessary with all those ® signs? It's not like you'd write Microsoft® Windows® each time you refer to that family of OSes, e.g. DarkPhoenix 15:01, 8 January 2007 (UTC)

Diseases vs Disorders

more on topical application of cortisol cream

After 50 years I am finally able to self diagnose why my procedural memory is fine, but my declarative memory has always been a disaster. Cortisol!!

Throughout my childhood, I suffered from eczema and treated it by applying hydrocortisone cream directly to large open wounds (scratched areas behind knees and inside elbows). It appears the cortisol was absorbed directly into my bloodstream and severely damaged my hippocampus. This explains why I became a Professional Engineer (considered one of the best in my field), yet I have virtually no episodic or semantic memory. 159.221.32.10 13:29, 18 April 2007 (UTC)

Effect paragraph

hi, In the effects paragraph, one needs to change "gluconeogenesis" to gluconeolysis. Insulin who is the anti-glucose hormone will act on everything that lowers circulating glucose, ie by producing glycogen in the liver. Cortisol brakes down this glycogen to produce circulating glucose, glucagon has the same effect 159.221.32.10 08:07, 23 May 2007 (UTC)

Welcome. One of the beautiful things about Wikipedia is that you do not need to ask anyone to change the article; you can be bold and update it yourself. --Selket ^Talk 09:19, 23 May 2007 (UTC)

It's a good idea to do your homework first, and get the facts straight, though, especially on topics that relate to medicine. A side benefit is you learn so much more when you're careful about your fact checking! Cortisol works to increase glucose levels via gluconeogenesis (making new glucose, by breaking down fats and proteins), not glycolysis (breaking down glycogen). Bob Kerns (talk) 09:04, 25 April 2011 (UTC)

According to Human Anatomy and Physiology, 5th Ed. by E. Marieb (2001), "cortisol's prime metabolic effect is to provoke nucleogenesis, that is, the formation of glucose from noncarbohydrate molecules..." So, under stress cortisol acts to increase blood glucose levels to prepare for increased metabolic demands.Neuroninja (talk) 08:49, 24 November 2007 (UTC)

Effect on liver glycogen formation

Hi, According to the Columbia Encyclopedia on Google, according to Meisenberg & Simmons: Principles of Medical Biochemistry, 2. edition, and according to Boron & Boulpaep: Medical Physiology, cortisol increases glycogen synthesis in the liver, contrary to what the article says.

This makes sense: Cortisol is a chronic stress hormone which prepares the body for the action of epinephrine, a stress hormone working within seconds. In order to enhance the effects of epinephrine, cortisol stimulates glycogen synthesis so that, in times of need, more glycogen is available to be broken down when epinephrine levels rise. Epinephrine and glucagon are the hormones that promote glycogenolysis in the liver.

Cortisol raises the blood glucose level by stimulating gluconeogenesis in the liver, not by stimulating glycogenolysis.

User JFW quotes Freeman (2002) for saying that cortisol leads to increased glycogen formation in the liver, while in the current article, the book is used as a reference saying the opposite.

Are there any sources supporting the statement that cortisol decreases glycogen formation in the liver? Otherwise I'm going to change it. Nelly4 21:21, 12 June 2007 (UTC)Nelly4

Standards/quality note should be moved to the top of the article

From a readability and clarity standpoint, this entire article is a mess. There are numerous text references to highly esoteric items with no contextual information; there is no (clear) explanation of the varied usage of chemical names to refer to cortisol; there is little information on the relationship between cortisol and cortisone; and the references to various experimentation and research are vague and in some cases appear, at least superficially, to be self-contradictory (e.g., the cortisol/insulin relationship).

Although I could help in cleaning up the comprehensibility and formatting of the text, I'm not comfortable doing so without advanced knowledge of the subject matter. Therefore, I'll just put in my recommendation, and offer to help if it would be useful.

Relationship to thyroid hormone (T3) and hypothyroidism

Does anyone have a journal (or endo textbook) reference for the fact that cortisol is required for T3 to bind to cellular receptors and enter cells? This is often repeated on various thyroid/adrenal lists and website, but I haven't been able to find a journal article to source it. (I can't find anything about whether rT3 actually binds to T3 receptors as an inactive 'decoy' either, or that matter..)

The article might also want to say something about the fact that thyroid treatment shouldn't be odne without first dealing with adrenal insufficiency - except I can't find any articles backing that up either. —Preceding unsigned comment added by 216.9.142.151 (talk) 05:35, 11 July 2008 (UTC)

• I had never heard of this requirement. I checked Guyton just to make sure. There is no mention of cortisol for synthesis/function/binding of T3 in the entire thyroid chapter. The process, as far as I am aware, follows something like this: T4 is avidly bound by thyroid hormone binding proteins from the liver (TBG, TTR, and albumin). Same for T3. T4 stays bound by the plasma proteins on average about six days, whereas T3 is released in about a day. When absorbed into the cell (no mention of mechanism or cortisol) they are bound by other binding proteins in the cell. T4 is converted to T3 by iodinase. When released from the cellular binding proteins, T3 binds to the thyroid hormone receptor in the nucleus. That complex also complexes with RXR and kicks off transcription. If you have references that point to the contrary, I'd like to see them. However, there is plenty of literature out there that shows the converse. T3 appears to be necessary for cortisol expression (e.g. here). Chaldor (talk) 06:29, 11 July 2008 (UTC)

There's a fair bit of confusion floating around here; you address part of it; let me see if I can address the rest.

The big issue with cortisol/Thyroid interaction is that increasing T3 levels increases overall metabolic rate, including the rate of metabolizing cortisol, which, if in short supply, can trigger an adrenal crisis. So indeed, one should treat adrenal insufficiency before beginning treatment for hypothyroidism -- but then, one should treat adrenal insufficiency promptly anyway, as it's far more life-threatening. (See for example, the emedicine.com articles on both adrenal crisis and hypothyroidism, each pointing out the dangers of neglecting the other condition). You can find references, both to the clinical concern, and the underlying physiology. As to rT3, cortisol required for binding, etc.. To the best of my knowledge (and without my usual fact checking, sorry -- it's hard to fact-check a negative), cortisol is not required for T3 to bind or enter. Actually, that's backwards -- the thyroid hormone receptors are nuclear receptors, and quite similar to the receptor for cortisol. So both molecules have to enter the cell before they bind to the receptors, which then bind to the DNA and affect transcription. As for T3 vs rT3 -- there is an interaction with cortisol there. What happens is that there are two pathways to get from T4 to T2, one via T3, one via rT3, depending on which iodine is removed first. Each iodine is removed by a different deiodinase enzyme, and cortisol affects the relative concentrations. Google for "deiodinase cortisol" for a slew of references. rT3 doesn't bind to the nuclear T3 receptors; that's a confusion. They're produced in competition, rather than bind in competition. (There do appear to possibly be nuclear binding sites for rT3: http://www.ncbi.nlm.nih.gov/pubmed/7075548 -- the things you learn from fact-checking!) The article from Nature that you cite doesn't say what you say it says -- but probably what you meant to say it says. In the case of production of growth hormone, it appears that both cortisol and T3 are necessary. This has nothing to do with cortisol expression, but rather cortisol-triggered expression of genes involved in GH₁ production. It's unclear how much we should generalize from that result -- but clinically, it's important to get both hormones right, and they do interact. Bob Kerns (talk) 09:39, 25 April 2011 (UTC)

Alphabet Soup

When first introduced as a treatment for rheumatoid arthritis, it was referred to as Compound E.

This is a nice description of cortisone, rather than cortisol (17-OH-cortisone, also known as compound F). Before the structures were known, the adrenal steroids were identified as spots on thin layer chromatography. Kendall called them compounds and Reichstein called them substances, and their letters don't match between systems. There's a nice retrospective essay: Dallman MF, "Adrenocortical function, feedback, and alphabet soup." Am J.

Where's the logic

Prolonged cortisol secretion causes hyperglycemia and diabetes mellitus. The reason why in vivo experiments seem to deny this is that cortisone (a cortisol metabolite) greatly inhibits insulin.

- cortisol increases glucose by opposing insulin. Cortisone inhibits insuling. What do the experiments "seem to deny"? --CopperKettle 15:22, 23 October 2009 (UTC)

it is my understanding that all those effects listed are effects of taking in too much cortisol, isn't that right? if that is so, why is this not stated? it's confusing to meet up with sentences like "it 'enables' hypotonic urination." because if you think about it, why would you want a hormone in your body to enable a malfunction?

Material needing clean-up

The following material - which tends towards being way over-specific for a general interest user generated encyclopedia - has been flagged as needing clean-up to be understandable/relevant to the Cortisol article. Please do so here before re-integrating improved content into the latter:

Extended content

Effects See also Therapeutic uses of glucocorticoids In normal release, cortisol (like other glucocorticoid agents) has widespread actions which help restore homeostasis after stress. (These normal endogenous functions are the basis for the physiological consequences of chronic stress - prolonged cortisol secretion.) Insulin Cortisol counteracts insulin, contributing to hyperglycemia by stimulus of hepatic gluconeogenesis and inhibition of the peripheral utilization of glucose by decreasing the translocation of glucose transporters to the cell membrane, specially GLUT4. However cortisol increases glycogen synthesis (glycogenesis) in the liver. Permissive effect of cortisol on insulin action on liver glycogenesis is observed in hepatocyte culture in laboratory. However, the mechanism is unknown. Collagen In rats, loss of collagen from skin, caused by cortisol, is ten times greater than loss from any other tissue. Cortisol (as opticortinol) probably inversely inhibits IgA precursor cells in the intestines of calves. Cortisol also inhibits IgA in serum, as it does IgM, but not IgE. Gastric secretion Cortisol stimulates gastric acid secretion. Gastric acid secretion would increase loss of potassium into the stomach during diarrhea as well as acid loss. Cortisol's only direct effect on the hydrogen ion excretion of the kidneys is to stimulate excretion of ammonium ion by inactivation of renal glutaminase enzyme. Net chloride secretion in the intestines is inversely decreased by cortisol in vitro (methylprednisolone). Sodium Cortisol inhibits loss of sodium from small intestines of mammals. However, sodium depletion does not affect cortisol, so cortisol is not used to regulate serum sodium. Cortisol's purpose may originally have been centered around moving sodium because cortisol is used to stimulate sodium inward for fresh water fish and outward for salt-water fish. Potassium Sodium load augments the intense potassium excretion by cortisol, and corticosterone is comparable to cortisol in this case. In order for potassium to move out of the cell, cortisol moves in an equal number of sodium ions. It can be seen that this should make pH regulation much easier, unlike the normal potassium deficiency situation in which about 2 sodium ions move in for each 3 potassium ions that move out, which is closer to the deoxycorticosterone effect. Nevertheless, cortisol consistently causes alkalosis of the serum, while in a deficiency pH does not change. Perhaps this may be for the purpose of bringing serum pH to a value most optimum for some of the immune enzymes during infection in those times when cortisol declines. Potassium is also blocked from loss in the kidneys directly somewhat by decline of cortisol (9 alpha fluorohydrocortisone). Water Cortisol also acts as an anti-diuretic hormone. Half the intestinal diuresis is so controlled. Kidney diuresis is also controlled by cortisol in dogs. The decline in water excretion upon decline of cortisol (dexamethasone) in dogs is probably due to inverse stimulation of antidiuretic hormone (ADH or arginine vasopressin), the inverse stimulation of which is not overridden by water loading. Humans also use this mechanism and other different animal mechanisms operate in the same direction. Copper It is probable that increasing copper availability for immune purposes is the reason many copper enzymes are stimulated to an extent which is often 50% of their total potential by cortisol. This includes lysyl oxidase, an enzyme which is used to cross link collagen and elastin. Particularly valuable for immunity is the stimulation of superoxide dismutase by cortisol since this copper enzyme is almost certainly used by the body to permit superoxide to poison bacteria. Cortisol causes an inverse four- or fivefold decrease of metallothionein, a copper storage protein, in mice (however rodents do not synthesize cortisol themselves). This may be to furnish more copper for ceruloplasmin synthesis or release of free copper. Cortisol has an opposite effect on alpha aminoisobuteric acid than on the other amino acids. If alpha aminoisobuteric acid is used to transport copper through the cell wall, this anomaly would possibly be explained. Immune system Cortisol can weaken the activity of the immune system. Cortisol prevents proliferation of T-cells by rendering the interleukin-2 producer T-cells unresponsive to interleukin-1 (IL-1), and unable to produce the T-cell growth factor. Cortisol also has a negative feedback effect on interleukin-1. IL-1 must be especially useful in combating some diseases; however, endotoxin bacteria have gained an advantage by forcing the hypothalamus to increase cortisol levels via forcing secretion of CRH hormone, thus antagonizing IL-1 in this case. The suppressor cells are not affected by GRMF, so that the effective set point for the immune cells may be even higher than the set point for physiological processes. It reflects leukocyte redistribution to lymph nodes, bone marrow, and skin. Acute administration of corticosterone (the endogenous Type I and Type II receptor agonist), or RU28362 (a specific Type II receptor agonist), to adrenalectomized animals induced changes in leukocyte distribution. Natural killer cells are not affected by cortisol. Bone metabolism It lowers bone formation thus favoring development of osteoporosis in the long term. Cortisol moves potassium out of cells in exchange for an equal number of sodium ions as mentioned above. This can cause a major problem with the hyperkalemia of metabolic shock from surgery. Cortisol reduces calcium absorption in the intestine. Memory It cooperates with epinephrine (adrenaline) to create memories of short-term emotional events; this is the proposed mechanism for storage of flash bulb memories, and may originate as a means to remember what to avoid in the future. However, long-term exposure to cortisol results in damage to cells in the hippocampus. This damage results in impaired learning. Additional effects It increases blood pressure by increasing the sensitivity of the vasculature to epinephrine and norepinephrine. In the absence of cortisol, widespread vasodilation occurs. It inhibits the secretion of corticotropin-releasing hormone (CRH), resulting in feedback inhibition of ACTH (Adrenocorticotropic hormone or corticotropin) secretion. Some researchers believe that this normal feedback system may become dysregulated when animals are exposed to chronic stress. It allows for the kidneys to produce hypotonic urine. It shuts down the reproductive system, resulting in an increase for the chance of miscarriage and, in some cases, temporary infertility. Fertility returns after cortisol levels are reduced back to normal levels . It has anti-inflammatory effects by reducing histamine secretion and stabilizing lysosomal membranes. The stabilization of lysosomal membranes prevents their rupture, thereby preventing damage to healthy tissues. It stimulates hepatic detoxification by inducing tryptophan oxygenase (to reduce serotonin levels in the brain), glutamine synthase (reduce glutamate and ammonia levels in the brain), cytochrome P-450 hemoprotein (mobilizes arachidonic acid), and metallothionein (reduces heavy metals in the body). In addition to the effects caused by cortisol binding to the glucocorticoid receptor, because of its molecular similarity to aldosterone, it also binds to the mineralocorticoid receptor. Aldosterone and cortisol have similar affinity for the mineralocorticoid receptor however, glucocorticoids circulate at roughly 100 times the level of mineralocorticoids. An enzyme exists in mineralocorticoid target tissues to prevent overstimulation by glucocorticoids and allow selective mineralocorticoid action. This enzyme, 11-beta hydroxysteroid dehydrogenase type II (Protein:HSD11B2), catalyzes the deactivation of glucocorticoids to 11-dehydro metabolites. There are potential links between cortisol, appetite and obesity. Binding Most serum cortisol, all but about 4%, is bound to proteins including corticosteroid binding globulin (CBG), and serum albumin. Only free cortisol is available to receptors. Regulation The primary control of cortisol is the pituitary gland peptide, adrenocorticotropic hormone (ACTH). ACTH probably controls cortisol by controlling movement of calcium into the cortisol secreting target cells.. ACTH is in turn controlled by the hypothalamic peptide, corticotropin releasing hormone (CRH), which is under nervous control. CRH acts synergistically with arginine vasopressin, angiotensin II, and epinephrine . When activated macrophages start to secrete interleukin-1 (IL-1), which synergistically with CRH increases ACTH, T-cells also secrete glucosteroid response modifying factor (GRMF or GAF) as well as IL-1, both of which increase the amount of cortisol required to inhibit almost all the immune cells . Thus immune cells take over their own regulation, but at a higher cortisol set point. Even so, the rise of cortisol in diarrheic calves is minimal over healthy calves and drops below with time. The cells do not lose all of the fight or flight override because of interleukin-1's synergism with CRH. Cortisol even has a negative feedback effect on interleukin-1 which must be especially useful for those diseases which gain an advantage by forcing the hypothalamus to secrete too much CRH, such as the endotoxin bacteria..The suppressor immune cells are not affected by GRMF, so that the effective set point for the immune cells may be even higher than the set point for physiological processes. GRMF (called GAF in this reference) primarily affects the liver rather than the kidneys for some physiological processes . A high potassium media, which stimulates aldosterone secretion in vitro, also stimulates cortisol secretion from the fasciculata zone of dog adrenals unlike corticosterone, upon which potassium has no effect . Potassium loading increases ACTH and cortisol in people also . This is no doubt the reason why a potassium deficiency causes cortisol to decline (as just mentioned) and why a potassium deficiency causes a decrease in conversion of 11deoxycortisol to cortisol . This probably contributes to the pain in rheumatoid arthritis since cell potassium is always low in that disease Factors affecting cortisol levels Factors generally reducing cortisol levels Magnesium supplementation decreases serum cortisol levels after aerobic exercise, but not in resistance training. Omega 3 fatty acids, in a dose dependent manner (but not significantly), can lower cortisol release influenced by mental stress by suppressing the synthesis of interleukin-1 and 6 and enhance the synthesis of interleukin-2, where the former promote higher CRH release. Omega 6 fatty acids, on the other hand, acts inversely on interleukin synthesis.. The paper that is referenced in the article states that the effect of fish oil on cortisol is insignificant but the the reference is used to state that fish oil decreases cortisol. Music therapy can reduce cortisol levels in certain situations. Massage therapy can reduce cortisol. Laughing and the experience of humour can lower cortisol levels. One study by a Japanese cosmetics company has asserted that makeup reduces cortisol levels in a mental stress situation. Soy derived Phosphatidylserine interacts with cortisol but the right dosage is still unclear. Vitamin C may slightly blunt cortisol release in response to a mental stressor. Black tea may speed up recovery from a high cortisol condition. Factors generally increasing cortisol levels Caffeine may increase cortisol levels. Sleep deprivation increases cortisol levels. Intense (high VO2 max) or prolonged physical exercise stimulate cortisol release in order to increase gluconeogenesis and maintain blood glucose. Proper nutrition and high-level conditioning can help stabilize cortisol release. Val/Val variation of the BDNF gene in men, and the Val/Met variation in women is associated with increased salivary cortisol in a stressful situation. Hypoestrogenism and melatonin supplementation increases cortisol levels in postmenopausal women. Burnout is associated with higher cortisol levels. [This should not be in this list. The list is for causal factors not consequential states| DrSparticle (talk) 04:01, 13 June 2011 (UTC)] Severe trauma or stress events can elevate cortisol levels in the blood for prolonged periods. Subcutaneous adipose tissue regenerates cortisol from cortisone. Anorexia nervosa may be associated with increased cortisol levels. The serotonin receptor gene 5HTR2C is associated with increased cortisol production in men. Some formulations of combined oral contraceptive pills increase cortisol levels in young women who perform whole-body resistance exercise training.

Hi! In contrast, I found the article fully understandable because I am a medical graduate with postgraduate training in endocrinology and immunology. A simple introduction would certainly help those who find so many technical words which they refer to as jargon. I found this article whilst looking for data on the serum cortisol levels in the normal adult and the level in chronic stress. I have a reference which cites a fivefold increase in serum cortisol in both acute and chronic stress; the article I have in my office also points to the danger of adrenal failure due to chronic stress as occurs in patients in an intensive care unit. The article followed serum cortisol levels in two groups i)patients with multiple fractures & ii)patients with overwhelming infection. I will retrieve my article and come again to this page!

Replaced cortisol values

I replaced the serum cortisol values, because the previous ones (from addisons-network.co.uk/ad_tests) often gave only "basal levels", which is a rather misleading value, since it changes substantially during 24 hours (as seen in the new values). The only previous values of use were the ones attributed to "USA" or "Hospital #2", but when looking at it's primary sources, the source for USA was completely missing, and "Hospital #2" gave a list of 4 studies, which made it rather hard to find in which one the values were actually taken. Anyone, feel free to find which one it was, and complement with those values. Mikael Häggström (talk) 16:49, 1 April 2011 (UTC)

Caffeine's effect on cortisol

I think it should be mentioned that regular caffeine users develop a tolerance to cortisol increases (which is known for its damaging effects at high levels). As someone considering using caffeine to improve my mental performance, I had to read the cited study only to find that it compared controls with those who took a 250mg dose of caffeine after a week of abstinence, then find this after a thorough reading of the cited study. For others' convenience, I think the study I linked to along with how the stress-induced cortisol increase diminishes with tolerance should be mentioned in the article. 129.97.214.143 (talk) 04:26, 19 June 2011 (UTC)Subrosian,

Other effects

[. . .] However, prolonged cortisol secretion (which may be due to chronic stress or the excessive secretion seen in Cushing's syndrome) results in significant physiological changes.[1]

Normal Serum and urinary cortisol levels are wrong.

The upper limit of normal for midnight serum cortisols is below 2, with 5 and 8 being diagnostic of Cushings, depending on the setting of the testing (sleeping in hospital vs. outpatient).

The upper limit of normal for urine cortisol depends on the assay used. The one used in the US through some labs is about 50, in other labs (eg. Esoterix) the uln is 34). This is a critical edit to make since endocrinology residents and fellows tend to base their knowledge on what is on Wikipedia and wrong limits can result in misdiagnosis. Canada, last I heard, still uses the older assay method and the uln for urines there is 100. Using an Esoterix assay, the listed figure would be a number diagnostic of Cushings, not normal.

See Evaluation of the effectiveness of midnight serum cortisol in the diagnostic procedures for Cushing’s syndrome Giuseppe Reimondo, Barbara Allasino, Silvia Bovio, Piero Paccotti, Alberto Angeli and Massimo Terzolo, European Journal of Endocrinology (2005) 153 803–809, for a good discussion on normals vs. pathological levels at the upper limit. Please have a competent endocrinologist address this problem.

Epifoam

Epifoam redirects to this page. This is incorrect. Epifoam is a foam rubber like product sold in thin sheets, used for craft projects. It's definitely not cortisol. Hope somebody can sort this. Anniepoo (talk) 07:42, 5 December 2013 (UTC)

Epifoam is most definitely a drug (hydrocortisone acetate and pramoxine hydrochloride). It may also be a foam rubber product, but a Google search hits are mainly to the drug. There is also a product that is used after liposuction surgery. I cannot locate a single web site that talks about a foam rubber like product other than the previous liposuction related link. The drug is a mixed product containing both hydrocortisone acetate and pramoxine hydrochloride. Regardless, the redirect should not be to cortisol, but to hydrocortisone acetate and pramoxine hydrochloride. However we currently do not have a article on this product. In the meantime, I have changed the target of the redirect to hydrocortisone acetate. Boghog (talk) 08:09, 5 December 2013 (UTC)

Suggestion for changing one word (to an adverbial phrase) and moving it to a different part of the sentence

The "Cortisol#Gastric_and_renal_secretion" section of the article, contains a sentence in which there is a word that IMHO should be (changed, and) moved to a different part of the sentence.

The sentence I have in mind -- at least, as of https://en.wikipedia.org/w/index.php?title=Cortisol&oldid=635216372 -- says:

Net chloride secretion in the intestines is inversely decreased by cortisol in vitro (methylprednisolone).[49]

IMHO the word "inversely" is positioned in the wrong part of that sentence. I think what the word was intended to mean, is that

the fact that a certain thing (net chloride secretion) is decreased by [the action of] (some kind of result "caused by") cortisol

is somehow "opposite" in sign or direction, and hence "different" in an important way, from

the fact that -- as stated nearby, a couple of sentences away -- a certain other thing (gastric-acid secretion) is increased by cortisol

. (right?) Therefore, I suggest that the wording of the above sentence, -- (the one that I have in mind) -- should be changed to [something more like]

On the other hand, net chloride secretion in the intestines is decreased by cortisol in vitro (methylprednisolone).[49]

NOTE that the only changes are:

• the word "inversely" has been replaced by the phrase "On the other hand" and
• that phrase "On the other hand" is placed at the beginning of the sentence, instead of right next to the word "decreased".

Any comments? For example, comments about:

• whether the word "inversely" was originally intended to mean [something like] "On the other hand"

OR

• whether all that is OK being placed at the beginning of the sentence

Ordinarily, I would be more inclined to be bold, and to just make the [above mentioned] change to the article now. However, I do not have time to read this entire (long!) "Talk:" page, and the portion of it that I have read "so far", suggests to me that there might be a lot of complexity here, that I do not have the time (nor the inclination) to read about right now. (Also, ["!"] I do not know very much about cortisol.)

If there are no objections (with some reasonable amount of time), -- or, maybe even if there are some objections, but if they are able to be resolved (see "Wikipedia:Consensus"), or if [for some reason, e.g., "not serious", or "misguided", ...etc.] I am not persuaded [to change my mind] by those objections -- then I might decide to be bold, after all, and to make the above mentioned change to the article. --Mike Schwartz (talk) 23:00, 24 November 2014 (UTC)

Too Heavy on Primary Sources?

I am uncomfortable with some sections of the article that rely almost exclusively on primary sources (See: "Factors generally increasing cortisol levels" and "Factors generally reducing cortisol levels"). Wikipedia isn't a secondary source, and getting rid of (primary-sourced) trivia could go a long way in cleaning up this very important article. I imagine that these sections also leave the page vulnerable to self promotion (individuals inputing stand-alone facts that they/their lab discovered).

Thoughts? When is it appropriate to get rid of miscellaneous information on Wikipedia?

Czeer (talk) 16:32, 3 March 2015 (UTC)

Thanks for your spot on comments and edits. Per WP:MEDRS, if you see primary sources supporting medical claims and animals studies mixed up with human clinical data, be WP:BOLD and get rid of it. I have made an initial attempt to further cleanup and reorganize the article. More work remains. Boghog (talk) 22:02, 3 March 2015 (UTC)

I agree with Czeer. There seems to be an over-reliance on singular studies to support certain positions in those two sections. Most of those studies seem to be preliminary or inadequately designed. Independent and better designed studies replicating the results should be cited in addition/corroboration, one feels. I wonder if these should be tagged with templates like Knaveknight (talk) 07:22, 13 May 2016 (UTC)

Marijuana Associated with elevated cortisol?

"Smoking marijuana has been shown to increase cortisol levels."

The study which the linked article refers to consisted of "10 marijuana addicts". 10 is not very many and it does not mention a control group or provide link to the study. Also ripe for reverse inference, these 10 marijuana addicts could have particularly stressful lives or naturally have a higher level of cortisol and use marijuana to "balance out" their stress.

If anybody has anything more on this I'd love to hear it, if there's real evidence then that would significant, until then I think this should be deleted. — Preceding unsigned comment added by Craigloverbutstr8 (talk • contribs) 03:08, 28 September 2015 (UTC)

Cortisol/long term exposure

Is it possible that a child subjected to trauma and stress, such as physical abuse, insults, bullying resulting in fighting, constant verbal abuse from parents and siblings, cause a continuous high level of cortisol and other fear-based hormones' so as to have an addictive effect on a human? What about children who are uprooted from their homes and moved every few months for many years till young adulthood? Would this cause a rise in cortisol and associated physiological and psychological responses? Geezer550 (talk) 22:06, 23 February 2020 (UTC)

archive Splitting

As per https://en.wikipedia.org/w/index.php?title=Talk:Cortisol/Archive_1&action=history the talk page was manually archived in [2]017, but the time was not taken to split it into chunks so that their TOCs (Table Of Contents ) on the left side ( desktop view ) can be read without scrolling. Currently you can zoom all the way out to 10% ( unreadable), and still you can't fit all the TOC vertically ( Talk:Cortisol/Archive_1 ) . If someone knows hows how to auto-do this splitting... There has to be a SMART wikipedia auto-archiving bot that does this. I also don't know how to flag this comment to a wikipedia bots specialists list / group. 2A01:E0A:8C1:70C0:9DD:C9F5:8873:67FF (talk) 16:01, 20 April 2023 (UTC)

Archives aren't usually split like that, especially when manually archiving. Page size and the age of threads are the main problem mentioned on the relevant page, rather than the number of sections. Graham87 09:02, 6 September 2023 (UTC)
