WHAT YOU NEED TO KNOW: An umbilical hernia is a bulge through the abdominal muscles in the area of the navel (belly button). The hernia may contain tissue from the abdomen, part of an organ (such as the intestine), or fluid. Umbilical hernias usually happen because of a hole or a weak area in the muscles of the abdominal wall. This can happen at any age. Umbilical hernias happen more often in women than in men.

Unlike inflammatory bowel disease, IBS does not cause inflammation or damage in the intestines. In many people with IBD, medicines can control symptoms.
