Patient's question:
Here is the English translation of your text, with the return characters kept as they are:"Please tell me if I have been taking the short-term birth control pill Mifeprex for these years, my period was fine before, but recently for the past few months, I've noticed my menstrual flow has become very little. Is this related to the birth control pill? When I discovered the flow was very little, I started drinking Yi Mu Cao herbal tea, and it seems to increase a bit. But if I don't drink it next month, it will decrease again. Can I keep drinking it every time? Is this okay? Is it effective? Please reply! Thank you very much!
Detailed medical condition and consultation purpose: I want to know what to do about reduced menstrual flow.
Duration of the current condition and its persistence: This has been going on for about half a year. First question supplement: But I have been taking birth control pills for several years, just recently for the past half year."
Doctor's answer:
A normal menstrual cycle with bleeding lasting less than 2 days and a volume of less than 20 milliliters is typically considered hypomenorrhea. Hypomenorrhea, like menorrhagia, is an abnormal phenomenon. The causes of hypomenorrhea are similar to those of amenorrhea, differing only in degree. The reasons are generally as follows:（1）Physiological: Due to genetic or environmental factors.
（2）Pathological:
① Congenital uterine underdevelopment, where the uterus is small and only a small amount of endometrium is shed, resulting in a low menstrual flow.
② Ovarian hypoplasia, where certain special granules in the endometrial cells, called lysosomes, are related to menstrual blood volume and bleeding duration. If estrogen and progesterone levels are high, lysosome complexes form well, leading to more bleeding and a longer bleeding duration. Conversely, if the ovaries are underdeveloped and sex hormone production is low, lysosome complexes form poorly, resulting in less bleeding and a shorter bleeding duration.
③ Endometrial tuberculosis, where the endometrium is damaged by tuberculosis bacteria, forming scars and reducing menstrual flow.
④ Married women may experience hypomenorrhea after uterine scraping, especially after multiple artificial abortions, which cause endometrial trauma and lead to uterine adhesions. Mild cases result in hypomenorrhea, while severe cases can lead to amenorrhea.
Hypomenorrhea should be investigated for its underlying cause and treated promptly.
Chinese herbal medicines for treating hypomenorrhea include:
① Gynecological Yangrong Pills: Take 6 grams per dose, 3 times daily (suitable for those with qi and blood deficiency).
② Nübao Tablets: Take 4 tablets per dose, 3 times daily (suitable for those with blood deficiency).
③ Zi Luang Ointment: Take 50 grams per dose,
