Slide show: Vaginal tears in childbirth
Vaginal tears occur frequently during childbirth. Most tears require little or no repair and heal within a few weeks. Others require more repair with sutures. This slide show from the Mayo Clinic guides you through first, second, third, and fourth degree tears, what they look like, how they are repaired, and how to take care of them once you return home from the hospital.
