The fact that menstruation does not stop should be called abnormal vaginal bleeding, and it is considered to be related to pregnancy-related diseases, endocrine disorders, and organic lesions. 1. Pregnancy-related diseases: when abnormal uterine bleeding occurs, it is necessary to exclude the bleeding that may be caused by pregnancy, such as preeclampsia, abortion, difficult abortion, etc. Even pregnancy-related trophoblastic diseases, such as hyperemesis gravidarum, etc., may also occur in irregular vaginal bleeding. 2. Endocrine disorder: It may be caused by over-excited emotion, excessive mental stress, sudden change of environment and other factors, resulting in endocrine disorders in the body. The combination of endocrine disorders may cause irregular ovulation, which in turn affects the stripping of the endometrium, resulting in irregular menstruation and other manifestations. 3. Organic lesions: for example, the presence of endometrial polyps, uterine fibroids, or even endometrial cancer and cervical cancer and other organic lesions, leading to abnormal vaginal bleeding. When menstruation persists, patients need to go to the hospital for further examination under the doctor’s guidance to clarify the cause of the disease, and timely treatment for the cause, so as to avoid serious disease and damage to the body.
