Women with abnormal menstruation and no organic lesions in the reproductive organs are called functional uterine bleeding, or gonorrhea for short. Due to frequent bleeding, heavy bleeding and long bleeding time, patients often have anemia or symptoms such as weakness, dizziness and tinnitus, etc. For young and infertile women, it may affect the reproductive function and lead to infertility, so it should be paid great attention. Functional uterine bleeding is divided into ovulatory and anovulatory types, with the following four specific symptoms: 1. Irregular vaginal bleeding. 2. Frequent menstruation. Shortened menstrual cycle, usually less than 21 days. 3. Excessive menstrual flow. Excessive bleeding, which can be hundreds of milliliters at a time. 4.Menstrual dripping. Small amount of bleeding for several days before the menstrual flow, often dark in color, and a few days after the menstrual flow, the bleeding may continue for more than ten days before and after the menstrual flow. 5. Ovulatory bleeding. About 10 days after the menstrual period, a small amount of blood flows from the vagina, and sometimes it clears in a day or two, which is called ovulatory bleeding.
