The causes of non-menstrual lower body bleeding may be ectopic pregnancy, early miscarriage, endometrial polyps, cervical cancer, endometrial cancer and so on. If you have non-menstrual lower body bleeding, you should consult a doctor in time to clarify the cause and treat the cause. 1. ectopic pregnancy: If you have sex without strict contraception and have non-menstrual lower body bleeding, you should consult a doctor in time to check urine, blood HCG and vaginal ultrasound to diagnose whether it is ectopic pregnancy. In severe cases, surgical treatment, such as laparoscopic or open salpingo-oophorectomy, is required; in mild cases, medication can be chosen under close monitoring; 2. Early abortion: if the lower body keeps bleeding during non-menstrual period with small abdominal pain, it may be caused by early abortion, and should be treated by visiting the hospital and taking oral medication or performing abortion surgery; 3. Endometrial polyp: typical symptoms include bleeding between menstruation and excessive menstruation. If the polyp is less than 1 cm in diameter, it can be observed and not treated; for patients with larger polyp and symptoms, surgical treatment, such as hysteroscopic endometrial polypectomy, is recommended; 4.Cervical cancer: there will be symptoms such as contact bleeding, abnormal vaginal bleeding and slightly more bleeding. The diagnosis can be confirmed by pathological examination. Early stage cervical cancer chooses surgical treatment, such as cervical conization, total hysterectomy, etc. Middle and late stage tumors often choose the treatment of radiotherapy and chemotherapy combined with auxiliary Chinese medicine treatment to help recover as soon as possible; 5. Endometrial cancer: mainly manifests as abnormal vaginal bleeding, and advanced patients can also palpate the enlarged uterus in the abdomen. Treatment is mainly surgical, such as radical hysterectomy plus bilateral tubal and ovarian resection, and post-operative auxiliary radiotherapy to improve patients’ survival quality; 6. Other diseases: endometritis, cervical submucosal fibroids, cervical polyps, cervical erosion, abnormal luteal function and other diseases can also cause the symptom of non-menstrual lower body bleeding all the time, which should be promptly sought for medical treatment to clarify the cause and treat the cause to avoid delaying the condition.
