Causes of non-menstrual bleeding with blood clots include endometrial polyps, cervical polyps, uterine fibroids, cervical fibroids, cervical cancer, etc. It is recommended to identify the causes and actively treat them to improve the prognosis. 1. Endometrial polyps: typical symptoms include intermenstrual bleeding, excessive menstruation, etc. Blood clots may appear in severe cases. In mild cases, the polyps should be observed. Patients with larger polyps and more bleeding and infertility symptoms can be treated surgically, such as hysteroscopic polyp removal or curettage. 2. Cervical polyps: They can be manifested as excessive leucorrhea, bleeding between menstruation or after intercourse, and in a few cases, the bleeding volume can be similar to menstruation, or even blood clots. It is recommended to consult a doctor in time for polyp removal, post-operative auxiliary hemostatic and analgesic medication, as well as good personal hygiene to prevent infection and recurrence; 3, uterine fibroids: bleeding is the main symptom of uterine fibroids, manifested as increased menstrual volume, prolonged periods or shortened cycles, and can be accompanied by blood clots when symptoms are severe. Oral mifepristone can be taken to reduce the volume of fibroids and oral iron to correct anemia; common surgical methods include open or laparoscopic myomectomy, etc.; 4. Cervical fibroids: mainly irregular menstruation, increased menstrual blood volume, increased leucorrhea or bladder and rectal symptoms, and a few patients may have symptoms with blood clots. If the fibroids are small in size and have no symptoms, they can be reviewed regularly and do not need special treatment; if the fibroids are large, with symptoms such as increased menstrual flow, prolonged menstrual period, or even anemia, frequent urination and constipation, they need surgical treatment, such as transvaginal cervical myomectomy, or transabdominal or laparoscopic total hysterectomy; 5.Cervical cancer: there will be symptoms such as contact bleeding, abnormal vaginal bleeding, and the bleeding volume is slightly more. The diagnosis can be confirmed by pathological examination. Early stage cervical cancer is treated by surgery, such as cervical conization and total hysterectomy, while middle and late stage tumors are often treated by a combination of radiotherapy and chemotherapy, supplemented by Chinese medicine; 6. Once the symptoms appear, you should go to the hospital promptly to identify the cause and treat the cause so as not to delay the disease.
