When you have your period, eating the following foods will increase your menstrual flow: 1. drink brown sugar water while it is still hot; 2. eat eggs with red dates and drink red date water will also increase your menstrual flow; 3. eat black chicken stewed with cinnamon and add red dates will also increase your menstrual flow. If your menstrual flow does not increase after the above dietary regimen, it is recommended to have a blood test for sex hormone six on the second or third day of menstruation to rule out low menstrual flow due to endocrine disorders, as well as reduced menstrual flow due to polycystic ovary syndrome. According to the test results, the clinical treatment will be given accordingly, so that the treatment of the original disease will improve the menstrual flow. In addition, if the menstrual flow is low due to abortion or endometrial damage caused by uterine operation, hysteroscopy is needed to separate the adherent endometrium so that the menstrual flow can be normalized.
