An umbilical hernia develops at or nearby the umbilicus (belly button or navel).
This type of hernia occurs when part of the intestine protrudes through a weak spot in the abdominal muscles. It appears as a soft swelling in the area of the navel (umbilicus). Its cause is unknown.
In adults, it most frequently occurs after gaining weight. It may also occur in pregnant women or women who have had children in the past. Surgery is the best treatment for umbilical hernias in adults. This is especially so if the hernia enlarges and causes pain. Hernias rarely go away without treatment.
Occasionally, the protruding abdominal tissue becomes trapped (incarcerated) and can no longer be pushed back into the abdominal cavity. This reduces the blood supply to the section of trapped intestine and can lead to tissue death. Emergency surgery may be required. You may also need emergency surgery if you develop signs and symptoms of bowel obstruction. These include abdominal cramps, bloating and vomiting.
