Collection time ?: Well it depends on the time of when your cortisol level was checked. Maximal level of cortisol is usually between 5:00a-8:00am with the lowest (nadir) levels being after 5pm (almost zero level by bedtime). If your having symptoms such as malaise, increased napping, headaches, stomach ache or low bs, you may have adrenal insufficiency and will need referral to an endocrinologist for further testing. ...Read more

Cortisol Level (Definition)

Cortisol is what the body produces. It is often obtained to check if your body's adrenal gland (which produces the cortisol) is functioning well especially after one has been taking cortisone (prednisone) for a long time.

Addison's disease: A very low cortisol could be addison’s disease, but this is relatively rare, and “low cortisol” is way over-diagnosed; the term “adrenal fatigue” is sometimes used, which is a fake diagnosis. If someone says you have this, see an endocrinologist for confirmation. ...Read more

Stress: Chronic stress can cause elevated cortisol--although it could also be due to your diabetes. I suggest DHEA (dehydroepiandrosterone), 25 mg in the morning. DHEA should help to normalize your cortisol, and help you handle stress. I also suggest 1,000 mg mastic gum (available on line or from a health food store) for your abdominal distress--may be able to discontinue Rabeprazole. ...Read more

My cortisol level is 6.7.  It's way low in normal range. Reason for concern?

Probably not...: ... But the more important question is why was the cortisol level drawn in the first place? Reference ranges for cortisol are almost meaningless as cortisol levels are affected by so many things... Including time of day, one's stress level, etc. Having said that, in some contexts, an 8am cortisol value of 6.7 mcg/dl might be considered a bit low. Best to get the advice of the doctor who drew it. ...Read more

Normal: Hi. Your doctor ran a standard screening test for Cushing's syndrome, the overnight dexamethasone suppression test.

Low cortisol: If you are not suppressing cortisol production by taking some form of steroid hormone, this level is very low, and raises suspicion for addison's disease. There are many symptoms associated, including weakness, fatigue, low blood pressure, etc. One morning cortisol is not diagnostic; you need an acth test, which is not complicated. See your doctor right away. This is easily treated. ...Read more
