Patient's question:
Pre-pregnancy check-up, the doctor said I have polycystic ovary syndrome (PCOS), but I haven't noticed it myself. Could you please tell me what are the common symptoms of polycystic ovary syndrome?Doctor's answer:
PCOS leads to anovulation or oligoovulation in patients. Approximately 70% of cases are accompanied by menstrual disorders. The main clinical manifestations include amenorrhea, oligomenorrhea, and dysfunctional uterine bleeding (DUB), accounting for 70% to 80% of women with menstrual abnormalities, 30% of secondary amenorrhea, and 85% of anovulatory DUB. Due to the ovulatory dysfunction in PCOS patients, the lack of cyclic progesterone secretion leads to prolonged exposure of the endometrium to unopposed estrogen stimulation. This persistent endometrial hyperplasia increases the risk of simple endometrial hyperplasia, atypical hyperplasia, and even endometrial cancer.
