Inadequate menstrual flow should be treated according to the cause. It may be caused by uterine fibroids, luteal insufficiency, endometrial thickening, etc., and requires medication or surgery. 1. Uterine fibroids: If women have uterine fibroids, adenomyosis and other lesions caused by various gynecological organic diseases, they can be treated with medications such as progesterone tablets, injectable leuprolide and mifepristone tablets under the guidance of doctors, and surgical treatments can be carried out if necessary. 2. Luteal Insufficiency: When women experience impure menstruation caused by luteal insufficiency, progesterone tablets, progesterone soft capsules, and other progestational hormone drugs can be used for treatment under the guidance of a doctor. 3. Thickening of the uterine lining: If a woman’s menstruation is not clean due to thickening of the uterine lining, she can undergo curettage, which can not only stop the bleeding, but also do pathological examination. It is recommended to consult a doctor in time for treatment if menstruation is not cleared.
