Patient's question:
Here is the English translation of the provided text, with the exception of the carriage returns which are left unchanged as per your instructions:"After her period in July, she experienced brown discharge accompanying the period. Her menstrual cycle usually lasts about 5 days (previously there were also small amounts of brown discharge, but it ended with the period). Now, the brown discharge has lasted for half a month or even longer. Last month, when she checked at the hospital, it was said that her menstrual cycle was irregular."
Doctor's answer:
Hello, there are many factors that can affect menstruation, such as mental stress, emotional changes, environmental changes, fatigue, malnutrition, life pressure, and hormonal imbalances in the body. The menstrual cycle is generally between 21 and 35 days, with an average of 28 days. The duration of each period is typically 2-8 days, with an average of 3-5 days. The amount of blood flow is usually 30-50 milliliters, and anything over 80 milliliters is considered excessive, which can be harmful to the body in the long term. For your situation, it is recommended to undergo a checkup for the six major hormones to identify the cause.
