To get a heavy menstrual flow, you can apply estrogen, add or subtract progestin, or apply small doses of aspirin, etc., as appropriate for each case. In this case, it is important to find the cause of the decreased menstrual flow before applying the medication. If a woman has had an abortion or other intrauterine operation, a hysteroscopy should be performed after a complete examination to find out whether there are any adhesions in the uterine cavity, and if there are adhesions in the uterine cavity, the corresponding adhesions should be separated before considering the appropriate treatment for increased menstrual flow. If there are other endocrine factors causing decreased menstrual flow, it is also necessary to complete the sex hormone test before deciding whether to apply the above mentioned medications.
