What is the reason for sudden and large amounts of vaginal bleeding?

Patient's question:

No

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 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 the blood, turning into qi deficiency that cannot grasp the blood. It is recommended to use a large dose of astragalus root decoction to replenish qi and stop bleeding.
