what are hernias and what causes them
What Causes Hernias? 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; more often, it occurs later in life.
A hernia occurs when an internal part of the body pushes through a weakness in the surrounding muscle or tissue wall. This article deals with abdominal hernias which occur when a weakness in the wall of the tummy (abdomen) results in some of the internal contents bulging through.
