Irregular periods haven't been clean, vaginal wall ultrasound is fine, why is that?

Patient's question:

7---Now

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, overexertion, or spleen deficiency, which leads to qi deficiency. When qi is deficient, it cannot properly regulate the flow of blood, causing it to ooze outside the vessels. Alternatively, chronic blood loss may deplete qi, resulting in qi deficiency that cannot hold the blood in place.
It is recommended to take a large dose of Astragalus root decoction to replenish qi and stop bleeding. The occurrence of menstrual irregularities not only affects the patient's physical health but can also lead to gynecological disorders. Therefore, it is best to visit a gynecology department in the hospital for a check-up 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.
