Some women with heavy menstrual periods will need to be treated with a dilation and curettage or D and C.

D and C is a surgical procedure where the inner lining of the uterus is removed. Before this can be done, the cervix needs to be opened, or dilated. This allows surgical instruments to enter the uterus. One of the surgical instruments, called a curette, is used to gently scrape away the lining.
After a D and C, most women resume normal activities within a few days.

Risks of dilation and curettage include:

• Persistent vaginal bleeding
• Endometritis
• Injury to the uterus
