What are the reasons for having two or three menstrual periods in a month?

Patient's question:

13 years old, been here for a year, still not normal

Doctor's answer:

In your case, the bleeding may be caused by qi deficiency failing to control blood. This is often due to prolonged illness, exhaustion, or spleen deficiency leading to qi deficiency. When qi is deficient, it cannot properly regulate blood circulation, causing blood to overflow from blood vessels. Alternatively, chronic blood loss may deplete qi, turning it into qi deficiency that cannot hold blood.
It is recommended to take a large dose of astragalus decoction to replenish qi and stop bleeding. The occurrence of menstrual irregularities not only affects a woman's physical health but can also lead to gynecological diseases. Therefore, it is best to undergo a routine examination in the gynecology department of a hospital to identify the underlying cause and receive targeted treatment. In daily life, pay attention to dietary adjustments, consuming light and easily digestible foods, while avoiding spicy, irritating, and cold foods.
