My doctor never said anything about the correlation between my acne and hypothyroidism. After I had my second child I complained of severe fatigue. She tested me and found my thyroid levels to be low. I believe I might have had a thyroid disorder all along but none of the many, many derms I went to for acne ever bothered to refer me for any endocrine testing. As a matter of fact they made a point of telling my mom that I probably did not have a hormonal disorder. They were basing this on research they read that measured total testosterone levels in patients with acne. Unfortunately this measure of total testosterone does not give an accuate picture of what is really going on.
I have since found out on my own via internet research that hypothyroidism is associated with a low level of SHBG (sex hormone binding globulin). If you have a low level of SHBG then your level of free circulating testosterone will be high because there is not enough of the SHBG for the testosterone to bind with. Your total testosterne level may however, be perfectly normal. This unbound testosterone is converted to dihydrotestosterone in the hair folicle resulting in increased sebum production and acne.
What I have found in the articles I have been reading is that there appear to be 3 main disorders that cause androgen disturbances in women:
1. Polycystic Ovarian Syndrome which results in increased testosterone production by the Ovaries.
2. Congenital Adrenal Hyperplasia (the mild form not the classical form) which results in excess androgen production by the adrenal gland
3. Hypothyroidism that results in decreased levels of sex hormone binding globulin.
Because derms only treat the symptom (acne) many of us never know we have these other disorders unless we ask the right questions of our PCP's and get the right tests done.
The following tests need to be done to determine if you have any of these 3 conditions:
To rule out PCOS:
Total Testosterone
Free Testosterone
Androstenedione
17 hydroxy Progesterone
DHEAS (not DHEA)
Dihydrotestosterone
SHBG
To Rule out CAH:
Rapid ACTH stimulation test
To Rule out Thyroid Disease:
T3 and T4
If you want to read more look up "Androgen Disorders in Men and Women". The articles at this site are more informative than anything else I have ever read.
