The presence of brown discharge from the uterus is considered to be due to a number of factors: 1. physiological problems, because when ovulation occurs, the increase and decrease in hormone levels will produce a breakdown of the endometrium, so there will be brown discharge, which will end within 7 days. 2. pathological problems, because endometrial hyperplasia, echogenicity, fibroids, including ovarian cysts, can all cause brown discharge during non-menstrual periods. The brown discharge can occur during non-menstrual periods due to endometrial hyperplasia, uneven echogenicity, uterine fibroids, including ovarian cysts, so ultrasound examination is needed to determine if there are any of these diseases, and if necessary, they can be treated by means of surgery. It is also important to have TCT and HPV cancer screening without bleeding. When there is a viral infection of the cervix, it can also cause abnormal bleeding, so it is important to have a health screening.
