Menstruation has passed for several days, but there is still red, what's going on?

Patient's question:

No

Doctor's answer:

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