If the menstrual flow is particularly low, it is recommended to take Yimoucao capsules for adjustment first. If the menstrual flow does not improve after 1 month of continuous use, it is recommended to do an examination to exclude the following diseases, such as polycystic ovary syndrome. If the androgen is high, you can take oral da-ing-35, which can improve the low menstrual flow after the androgen is lowered to normal. If hypermenorrhea is caused by hyperprolactinemia, you can take oral bromocriptine to treat both hyperprolactinemia and improve hypermenorrhea. If the low menstrual flow is caused by low estrogen, you can take oral supplement Glaxo, which will significantly improve the menstrual flow. If the low menstrual flow is caused by incomplete adhesion of the uterine cavity due to multiple abortions, hysteroscopy can be performed and supplemented with Glivec.
