What is the main cause of hernia?
Ultimately, all hernias are caused by a combination of pressure and an opening or weakness of muscle or fascia. The pressure pushes an organ or tissue through the opening or weak spot. Sometimes the muscle weakness is present at birth.
A hernia usually happens in your abdomen or groin, when one of your organs pushes through the muscle or tissue that contains it. It may look like an odd bulge that comes and goes during different activities or in different positions. It may or may not cause symptoms, such as discomfort or pain. Most hernias eventually will need surgical repair.
