Polycystic ovary syndrome ( PCOS ) is another imbalance in male and female sex hormones. An excess of androgens can lead to ovarian cysts, weight gain, a higher risk of diabetes, changes in your menstrual period, infertility , as well as hair thinning. Because male hormones are overrepresented in PCOS, women may also experience more hair on the face and body.
What to do: Treating PCOS can correct the hormone imbalance and help reverse some of these changes. Treatments include diet, exercise, and potentially birth control pills, as well as specific treatment to address infertility or diabetes risk.
