There are more reasons for 46-year-old women to have dribbling menstruation all the time, which may be caused by endometritis, endometrial polyp, uterine diverticulum, endometrial cancer and other factors. 1. Endometritis: Inflammation of endometrium will lead to localized edema and congestion, which may lead to increased menstrual flow and prolonged menstrual period during menstruation, and thus the symptom of irregular menstruation will occur. 2. Endometrial polyps: Endometrial polyps are often characterized by bleeding between periods, heavy menstrual flow, prolonged menstrual period or menstrual dribbling, etc. If the polyp is large or protrudes into the menstrual period, it will cause the menstrual flow to increase. If the polyp is large or protrudes into the menstrual duct, it will easily cause infection, necrosis and bloody discharge. 3. Diverticulum of the uterus: after a cesarean section, a surgical incision is formed on the uterus, and when it is not repaired well, menstrual blood will accumulate in the diverticulum when it is discharged. After the endometrial shedding is completed during menstruation, the menstrual blood stored in the diverticulum will be discharged slowly, which is manifested as irregular menstruation. 4. Endometrial cancer: If you suffer from endometrial cancer, you may have irregular vaginal bleeding and abnormal discharge of fluid. There may be other reasons for 46-year-old women to have irregular menstruation, so it is recommended to go to regular hospitals for examination and cooperate with doctors for targeted treatment.
