Obstetric fistula is a little-known social affliction which is extremely stigmatised within society. It is a hole in the birth canal that causes women to become incontinent, most commonly a result of an obstructed labour. It is a condition that has largely disappeared in the western world, but remains a problem in many developing countries. More than 2 million women worldwide suffer from fistula, mostly in Africa. As International Women's Day approaches MSF draws attention to the fact that this injury continues to exist and destroy the lives of women in many countries around the world. It can however be prevented and treated and MSF projects impact significantly on the lives of affected women. MSF tackles this in two ways: preventing fistula by obstetrical healthcare available to women, as well as organising fistula sessions to treat women.
