In addition to the three features used to diagnose polycystic ovary syndrome (PCOS) (absence of ovulation, high levels of androgens, and ovarian growths), PCOS has many signs and symptoms, some of which may not seem to be related:1,2
- Menstrual irregularities:
- No menstrual periods—called amenorrhea (pronounced ey-men-uh-REE-uh)
- Frequently missed periods—called oligomenorrhea (pronounced ol-i-goh-men-uh-REE-uh)
- Very heavy periods
- Bleeding but no ovulation—called anovulatory periods
- Excess hair growth on the face, chest, belly, or upper thighs—a condition called hirsutism (pronounced HUR-soo-tiz-uhm)
- Severe, late-onset, or persistent acne that does not respond well to usual treatments
- Obesity, weight gain, or trouble losing weight, especially around the waist
- Oily skin
- Patches of thickened, dark, velvety skin—a condition called acanthosis nigricans (pronounced ay-kan-THOE-sis NY-grih-kanz)
Because many women don't consider problems such as oily skin, extra hair growth, or acne to be symptoms of a serious health condition, they may not mention these things to their health care providers. As a result, many women aren't diagnosed with PCOS until they have trouble getting pregnant or if they have abnormal periods or missed periods.
Although PCOS is a leading cause of infertility, many women with PCOS can and do get pregnant. Pregnant women who have PCOS, however, are at higher risk for certain problems, such as miscarriage. Learn more about PCOS-related pregnancy problems.
