There are various factors leading to scanty menstruation, mainly related to the imbalance of sex hormone levels in the body and low estrogen levels, which can be detected through the examination of sex hormone six indexes. If the estrogen level is low, this situation requires the use of estrogen drugs to regulate menstruation treatment. There are also abnormal hormone indicators, like hyperandrogenemia and hyperprolactinemia, which can also affect the scanty menstrual flow, and can usually be detected through the six hormone indicators. So through the indicators of hormone six, you can basically observe some of the causes of scanty menstruation. Generally, it is considered to take a blood test on the 2nd or 3rd day of menstruation on an empty stomach, which is more accurate, and then according to the test results, then targeted treatment. If the estrogen level is low, estrogen medication is usually considered for symptomatic treatment. For example, hyperandrogenemia can develop into polycystic ovary syndrome, resulting in scanty and irregular menstruation and affecting normal pregnancy, which generally requires symptomatic treatment with Dayin-35; hyperprolactinemia can also lead to irregular menstruation, which is generally treated with drugs such as bromocriptine.
