What is the reason for menstruation lasting more than ten days without stopping?

Patient's question:

No

Doctor's answer:

In your case, the bleeding may be caused by qi deficiency failing to control blood, often resulting from prolonged illness, exhaustion, or spleen deficiency leading to qi deficiency. When qi is deficient, it cannot regulate the circulation of blood, causing it to overflow outside the vessels. Alternatively, it may be due to chronic blood loss, where qi is consumed along with the blood, turning into qi deficiency that fails to hold the blood. It is recommended to use a large dose of Astragalus root decoction to invigorate qi and stop bleeding.
