Umbilical hernias are caused by a small hole in the muscle fascia which allows fat to herniate from inside the abdomen outside into the belly button. These hernias usually slowly increase in size over time and with exercise. And, eventually, the cosmetic appearance of your abdomen will suffer from the funny looking "outie" you have developed, even if your abdominal tone is good from exercise. If you only want the hernia repaired, I routinely fix these hernias under local anesthesia through an incision within the belly button. Some surgeons may prefer to do this under general anesthesia.If you are contemplating a tummy tuck, we routinely fix umbilical hernias at the same time as the tummy tuck.I recommend you seek a consultation with a board certified plastic surgeon or general surgeon regarding this condition.
