What are the reasons for excessive menstrual flow after a miscarriage for the first time?

Patient's question:

No

Doctor's answer:

Hello, after a female undergoes a postpartum procedure, hormonal changes in the body and damage to the endometrium during the surgery can cause menstrual cycles to change in most women. Some may experience an increase in menstrual flow, while others may have a decrease, and some may have delayed periods, among various other conditions. After such changes occur, it usually takes about 2-3 cycles for the menstrual cycle to gradually return to normal.
