A hernia occurs when there is a weakness or tear in your abdominal wall as a result of aging, injury, a previous surgical incision, or a condition present at birth. Hernias generally grow larger due to pressure on them, such as a loop of your intestine or fatty tissue pushing into the weak abdominal tissue or tear.
