Excessive bleeding from endometriosis can be treated with medication (such as progesterone) and surgery to relieve symptoms. 1. Pharmacological treatment: patients can take oral progesterone, progesterone receptor antagonist such as pregnenolone and other drugs, which act directly on the endometrium and ectopic endometrium to make the endometrium shrink and reduce the menstrual flow, so as to achieve the effect of stopping the bleeding, and the main adverse effects include nausea, vomiting and other symptoms. 2. Surgery: If the patient’s bleeding symptoms and abdominal pain cannot be relieved after using the medicine, if there is a large ovarian endometriosis cyst, or if there is severe adenomyosis, laparoscopic surgery can be taken. If the patient’s endometriosis bleeding is too large, he should take medication or choose other methods of treatment under the guidance of the doctor, avoiding unauthorized use of drugs to avoid causing adverse effects.
