PCOS, or Polycystic Ovarian Syndrome, is a common hormonal disorder that affects women of reproductive age. Symptoms of PCOS can vary from woman to woman, but can include irregular periods, ovarian cysts, acne, and excessive hair growth. A PCOS symptoms checklist can help women track their symptoms and get treatment if they suspect they have PCOS. Treatment for PCOS usually includes medications to regulate hormone levels and diet and lifestyle changes to promote weight loss.
