I have severe ME/CFS and my period is quite irregular. I've also increasing problems with hirsutism, quite a lot of it. When it started a few years ago I did tests for testosterone but at least according to the doctor they were within the normal range. And I don't have PCOS so I guess it's the idiopathic kind of hirsutism. I have thyroid problems in my family but my testing shows nothing abnormal. Don't know what levels it was though or exactly what hormones they checked. I've read somewhere that there might be a link between hirsutism and thyroid disease. I'm new to hormones, so I'm a bit lost. But I'm going to ask my doctor to take some tests. The one's I've come up with are: Thyroid hormones Prolactine Insuline Testosterone Anyone has input on this? Or ideas on what tests I should do?
