'belly button bulge'

An umbilical hernia is a tissue bulge on or near your belly button. Umbilical hernias in children usually disappear by age 4 or 5. In adults, untreated umbilical hernias can lead to complications. If your provider has concerns about an umbilical hernia, they may recommend surgery to put the tissue back into place.

An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The resulting bulge can be painful, especially when you cough, bend over or lift a heavy object. However, many hernias do not cause pain.

Appendectomy is surgery to remove an inflamed or infected appendix (appendicitis). Your appendix is a small, tube-like organ that extends from your colon on the lower-right side of your belly. Because an inflamed appendix has the potential to rupture (burst), appendicitis is a medical emergency. On the other hand, a healthy appendix doesn’t appear to have any essential function. If you must have your appendix removed, you won’t miss it.
