Hypothyroidism, typically, causes hair loss, not excessive growth.
Excessive hair growth in females is called hirsutism; it's often caused by a condition called Polycystic Ovarian Syndrome (PCOS)
This is often caused by excessive androgens, which cause male pattern hair growth. Testosterone is, typically, considered the male sex hormone, but women have small amounts of it, as well. If we have too much of it, we will have excessive hair growth.
DHEA is an adrenal hormone and is a precursor to testosterone.
Excessive hair growth can also be caused by Cushing Syndrome, which is an adrenal condition...
Ask your doctor to test your adrenal function, as well as all of your reproductive hormones, including testosterone. Some medications can also cause hirsutism, so be sure to check side effects of any medications you might be on.
Actually my DHEAS,LH,TOTAL TESTOSTERONE,FSH,AMH,ULTRASOUND all are Normal.Only I have mild hypothyroid.So tell me how can I diagnose this hirsutism?
Just because the results of other tests may have been in the normal ranges, doesn't mean they are normal for you... Levels in the high normal ranges could be too high for you or levels in the low normal ranges could be too low. If you have the exact levels and reference ranges, we'd be happy to take a look at them.
Common symptoms of Cushings are weight gain and fatty tissue deposits especially in upper back and face (moon face) and between the shoulders (buffalo hump), excessive hair growth in women, purple stretch marks on the skin of the stomach, breasts, thighs, arms, fragile skin that bruises easily. You don't have to have all of these symptoms to have the condition.
Testing for Cushings can be complicated and requires late night cortisol, urine free cortisol and dexamethasone suppression.
