What are the reasons for a small amount of bleeding in the middle of the menstrual cycle?

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 weak, it cannot regulate the flow 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, leading to qi deficiency that cannot hold the blood. It is recommended to use a large dose of Astragalus root decoction to replenish qi and stop bleeding.
