You may have polycystic ovarian syndrom (syndrome) (PCOS). This some general information from my website www.integrativefertilitymd.com:
PCOS can affect 5% of all women and common symptoms include irregular menstrual cycles, increased growth of hair on the body, loss of hair on the head, acne, and weight gain. Based on the 2003 ESHRE/ASRM sponsored Consensus Workshop Group, PCOS is diagnosed in women who meet two of the three following criteria: ovarian dysfunction (not ovulating regularly), hyperandrogenism (increased male type hormones on lab testing or clinically increased hair growth), or polycystic ovaries on ultrasound (ovaries which show multiple small cysts on ultrasound). PCOS is a common cause of infertility and puts women at an increased risk of developing Type 2 diabetes. There is also increased risk of insulin resistance, hypertension, and abnormalities of cholesterol and triglycerides in women with PCOS. Due to these risks, we advise our patients with PCOS to have the complete metabolic assessment with complete lipid panel testing and a two hour glucose tolerance test.
I would suggest that you see a gynecologist or better-- a Reproductive Endocrinologist to do a work up and check what hormones are imbalanced; and place you on something to regulate your periods, decrease hair and help with weight loss.
