Can functional uterine bleeding be treated with birth control pills? What kind of medication should be taken?

Patient's question:

Menstruation lasts only 15 days and has been going on for more than a year. The ultrasound results are normal.

Doctor's answer:

Functional uterine bleeding can be treated with medication to stop bleeding. There are two methods for medication-induced hemostasis: one is to promote complete shedding of the endometrium, which can be achieved by injecting progesterone; the other is to promote endometrial growth, which can be achieved by injecting estradiol benzoate. Additionally, some hemostatic drugs, such as Yunnan Baiyao, Anluoxue, vitamin K, tranexamic acid, and epsilon-aminocaproic acid, are generally effective in achieving the goal of stopping bleeding.
