Abdominal hernias are very common, particularly among men, an abdominal hernia is an opening or area of weakness in the abdominal wall through which abdominal contents can protrude.
An abdominal wall hernia causes a noticeable bulging but little discomfort.
The abdominal wall is thick and tough in most places, so hernias usually occur in an area of weakness where a previous opening has closed. Heavy lifting or straining may make a hernia more obvious but does not cause a hernia to form.
Treatment involves surgery to repair the hernia.
