Adrenal Fatigue or Low Cortisol:  Hydrocortisone (HC) Side Effects   

Custom Search

Adrenal fatigue, adrenal insufficiency, adrenal dysfunction, or hypoadrenia is a common co-existing problem for those who’ve been hypothyroid for years. Adrenal fatigue is the term most commonly used by patients, though it is not recognized by the medical profession and has no insurance billing code.  When thyroid energy is low, the adrenals (a small gland above the kidneys) step in with cortisol and adrenaline to give the body energy. This can make one feel both tired and wired at the same time. Sleeping problems are common.  In Addison’s disease, the adrenals produce little to no cortisol, so one must supplement cortisol, or they would die.  Those with Addison’s are usually quite thin.  Cushing’s is the opposite state, where one overproduces cortisol.  Cushing’s patients are usually quite heavy, with a moon face and buffalo hump (hump on the backside of their neck).

Adrenal fatigue refers to a broad range of adrenal dysfunction.  In the same way that thyroid dysfunction can range from myxedema coma on the hypothyroid end to thyrotoxicosis on the hyperthyroid end, so can adrenal fatigue range from Addison's on one end (cortisol close to zero) to high or dysfunctional daily cortisol rhythms on the other end.  If one has Addison’s, then there is no question that one must be on hydrocortisone for life.   And if saliva cortisol labs show a flat-lined pattern at the bottom of the range all day, then one may need to supplement with hydrocortisone too.  But for most others, supporting the adrenals with adaptogens and slowly raising thyroid levels can also work.  This is because thyroid and corticosteroid binding globulin (CBG) have an inverse relationship.  As thyroid levels come up, CBG goes down, leaving more cortisol free.  Cortisol is also released from CBG as body temperature rises, and body temperature correlates positively with thyroid levels. So raising thyroid can naturally raise cortisol levels. [1,13]  But any increases must be done slowly--weekly thyroid increases are too much too soon and do not give the body time to adjust.   I have read of people who are so sensitive that they can only raise 1/4 grain of desiccated thyroid or 12.5 mcg of T4 every 12 weeks.  If one has poor T4 to T3 conversion, then taking smaller amounts of T3 throughout the day (including bedtime), instead of once a day, will also give all organs, including the adrenals, a more steady supply of energy to perform their function.

Low cortisol can have a primary cause; that is, the adrenals simply do not produce cortisol. But it can also have a secondary cause--the pituitary does not send out an adequate ACTH (AdrenoCorticoTropic Hormone) signal, which tells the adrenals to produce the cortisol. If the hypothalamus does not send out enough corticotropic-releasing hormone (CRH), which sends the signal to the pituitary to produce ACTH, that is considered a tertiary cause. If a damaged pituitary or hypothalamus and low ACTH are the cause of the low cortisol, then cortisol must be taken for life to replace the essential missing hormone. Cortisol that  goes to zero is considered an adrenal crisis and is life-threatening, so steps must be taken to avoid this situation.  A medical alert bracelet/necklace/card should be carried at all times if one is on cortisol replacement, because the ACTH feedback loop does not work in this situation.

Adrenal fatigue seems common in those with thyroid problems.  Are the adrenals somehow connected to the thyroid?  Apparently they are, because without adequate thyroid levels, the adrenals themselves atrophy.  Rats were given anti-thyroid drugs like carbimazole or methimazole; these drugs are used to lower thyroid levels in Graves' patients. [14]  Their adrenals atrophied when hypothyroid, and the adrenal cortex actually shrank in size, especially the zona fasciculata, which is where cortisol is produced.  As expected, blood cortisol levels were lower in the hypothyroid rats.  Interestingly, Brewer's yeast, which is high in B vitamins and selenium, appeared to have a protective effect on the adrenal gland, somewhat offsetting the methimazole-induced atrophy.  [16]  Thyroidectomized dogs exhibited the same effect--their cortisol levels dropped significantly only seven days post-thyroidectomy.  Their adrenocortical function was restored after they were given levothyroxine. [15]

Hydrocortisone supplementation to treat adrenal fatigue has side effects many are not aware of, and should be, so they can make an informed decision if they choose to make it part of their protocol.  People using hydrocortisone on thyroid internet forums have reported some serious side effects, and there are medical journal references that support the connection:  osteoporosis [2], glaucoma, which can lead to blindness [3], weight gain and “buddha belly” [4], immune suppression that can lead to fungal infections and resistance to some cancer treatments [5,6], cardiovascular disease/ hypertension [7], diabetes [8], insomnia, and inability to tolerate any stress, which can lead to a fatal adrenal crisis [9].  Someone on the hydrocortisone protocol must learn how to “stress dose,” or manually provide the hydrocortisone needed for any stress, since the body becomes completely dependent on external dosing.  If one cannot provide the required increased hydrocortisone for the stress, it can be fatal.  More than one has ended up in the ER while on this protocol.  In the same way that T3-type medications suppress TSH, taking hydrocortisone suppresses the ACTH feedback loop, which would normally stimulate natural cortisol production.  One can have low cortisol symptoms in conjunction with physical signs of high cortisol because manual dosing creates high cortisol levels shortly after a dose, but low cortisol levels just before the next dose.  It is extremely difficult to replicate natural cortisol production, or to mimic an automatic ACTH feedback loop.  One should be aware of the risks before embarking on this protocol.

Hydrocortisone treatment doesn't cause these side effects at physiological doses, only at excessive pharmaceutical doses, say the proponents of this protocol.  But how does one define physiological?  Maybe what is physiological for one person is an overdose for another.  In one study of primary or secondary adrenal insufficient patients, those on hydrocortisone doses greater than 30 mg/day had a lower Quality of Life score than those on lower daily doses. [10]  In another study of primary or secondary adrenal insufficient patients, the dosing schedule that brought the highest proportion of simulated patients within physiological cortisol targets was 10 + 5 + 5 mg at 0730, 1200 and 1630 h, respectively. However, even with this regimen, about 54%, 44% and 32% of patients would remain over- or under-treated when compared to the physiological ranges at 0800, 1600 and 2400 h, respectively. [11]  These high percentages of being over or underdosed on what is considered a physiological dose confirm what many patients on hydrocortisone report--that it is extremely difficult to manually dose hydrocortisone. This may explain the side effects many report.

In a study of 12 Addison's and 20 hypopituitary patients on replacement glucocorticoid therapy, 75% of the patients were found to be taking excessive doses when serum cortisol levels were correlated with 24-hour urine free cortisol excretion. Their mean daily dose of hydrocortisone was reduced from 29.5 to 20.8 mg.  This caused median osteocalcin (a protein involved with bone formation) to increase (which is good) from 16.7 to 19.9 micrograms/l.  Another 56% had their dosing regimen or drug changed. [12]  Osteoporosis is a serious side effect of any glucocorticoid therapy, so it is imperative that one is not overmedicated. [2]

Hydrocortisone is used to suppress  the HPA (hypothalamus- pituitary-adrenal) axis through transrepression (which it does very well), but side effects like glaucoma and diabetes are from a different mechanism called transactivation.  Other side effects like osteoporosis seem to involve both transrepression and transactivation.  So while one may get the intended HPA effect of suppression, one may also unknowingly be putting oneself at risk for serious side effects. [8]

Hydrocortisone supplementation does not seem to work as it should when one is on other pharmaceutical drugs like benzodiazepines, or any medication that treats anxiety and depression.  These drugs probably work at some level on the HPA axis and cortisol levels, creating unintended, conflicting reactions.

Also, if Lyme disease or some other underlying medical condition is present, taking hydrocortisone can exacerbate the condition because of its suppressive effect on the immune system.  Hydrocortisone treatment should not be entered into lightly.  Some have ended up worse than before they started any treatment.
