The causes of abnormal uterine bleeding are divided into two categories and nine diseases, so the treatment principle is to find the cause and treat the cause. The treatment of uterine structural abnormalities that cause abnormal uterine bleeding is as follows: 1. endometrial polyps: after diagnosis, hysteroscopy is generally recommended, which can both diagnose and treat endometrial polyps. Depending on whether the patient has fertility requirements, after scraping or electrodesiccation of endometrial polyps, the patient needs to be given some follow-up treatment to reduce the recurrence of polyps; 2. Adenomyosis: it needs to be treated according to the patient’s needs. If the patient also has dysmenorrhea and infertility and has the desire to have children, it may be necessary to judge whether to take conservative or surgical treatment according to the severity of the patient’s disease. If the patient has fertility requirements, conservative treatment can be started. If there is a limited hyperplasia forming adenomyoma, the lesion can also be removed and surgical treatment can be performed before pregnancy. For patients who do not have fertility requirements, have severe symptoms, are relatively old, and for whom drug treatment is ineffective, total hysterectomy can also be considered, or whether the ovaries need to be preserved according to the patient’s needs and wishes; 3. Uterine fibroids: surgical treatment is often required, and they can usually be removed through hysteroscopy, and some larger interstitial myomas can also be removed through laparoscopy, and the specific treatment plan must be based on The specific treatment plan must be based on the patient’s age, the severity of symptoms, the size, number and location of fibroids, and whether the patient has fertility requirements; 4. Endometrial atypical hyperplasia and cancer: once diagnosed, different treatment plans should be chosen according to the severity of endometrial lesions, the patient’s age and whether the patient has fertility requirements. The treatment of five conditions that cause abnormal uterine bleeding without abnormal uterine structure is as follows: 1. systemic diseases with disorders of coagulation mechanism: first of all, the primary disease should be treated. If patients with abnormal coagulation mechanism have poor results after the above-mentioned conservative treatment, surgical treatment should be performed when the patient is in a position to do surgery under the control of internal diseases; 2. ovulation disorders: the treatment principle is to stop bleeding during the bleeding period After the bleeding is stopped, the cycle should be adjusted to prevent endometrial hyperplasia and abnormal uterine bleeding, and patients with fertility requirements should undergo ovulation treatment to get pregnant as soon as possible; 3. Local abnormalities of the endometrium: first of all, medication, oral short-acting contraceptives or progestin endometrial atrophy method, etc., can treat local abnormalities of the endometrium. Scraping is only used for emergency or pathological needs, and conservative surgery can be considered for patients without fertility requirements; 4. medical factors: treat the cause; 5. unclassified abnormal uterine bleeding: make appropriate treatment according to different causes after diagnosis.
