What is brown secretion before and after menstruation?

Brown secretions before and after menstruation are often caused by insufficient estrogen and progesterone. For example, brown secretions before menstruation are often caused by premature luteal atrophy, progesterone deficiency, and endometrial exfoliation, resulting in a small amount of brown secretions. Brown secretions after menstruation are often due to estrogen deficiency, and there is no way to completely repair the endometrium as soon as possible. Therefore, brown secretions are also shown. It is recommended to take a blood test for sex hormones on the second or third day of menstruation and give treatment according to the results. In addition, if there is endometrial inflammation, pelvic tumor or endometriosis, it may also show this phenomenon. It is recommended to combine clinical history, combined with gynecological examination, comprehensive analysis, and timely treatment after diagnosis.
