A 46-year-old woman who has been menstruating for more than 20 days may have luteal atrophy, uterine fibroids, endometrial polyps and pregnancy.
1. Luteal atrophy: abnormalities in the luteinizing mechanism of the hypothalamic-pituitary-ovarian axis cause luteal atrophy, and the endometrium continues to be affected by progesterone, so that it cannot be shed as scheduled, resulting in prolonged menstrual periods.
2. Endometrial polyp: excessive proliferation of the endometrium leads to the formation of polyps and prolonged menstrual periods, which need to be diagnosed by ultrasound in the hospital.
3. Submucosal fibroids: fibroids grow under the mucous membrane, resulting in an increase in the size of the uterine cavity and prolonged menstrual periods.
4. Pregnancy: If a 46-year-old woman is sexually active, she may become pregnant. Menstrual dribbling for more than 20 days may be associated with pregnancy-related diseases, such as preeclampsia and induced abortion.
A 46-year-old woman with dribbling menstruation needs medical attention.
