Umbilical hernia occurs when the abdominal content protrudes beneath the skin through the umbilical hole.
The umbilical hole, or the umbilicus is the healed scar situated in the lower abdominal area. Through it the umbilical cord enters the body while the child is still inside his mother, and through the cord vital substances are passed to the fetus.
After birth the umbilical cord is cut off and the small opening that remains should quickly close in. But, in some cases it does not close as it should, so a small 'crack' remains open. In these cases a part of the abdominal content, the intestines usually, pokes through this opening. The bulge that is created is more visible when the child coughs, sneezes, or cries.
Umbilical hernia is not surgically repaired in the small children's case because usually until the child reaches the age of 3 the hernia shrinks and heals by itself. Some mothers try to increase the speed of the healing by tapping a coin to the bulge and forcing it to stay there and push it back, but this method is not medically tested or recommended.
However, in some special cases umbilical hernia does require surgical intervention. This happens if it did not heal by itself after the child turned 3 or 4 years old, or if the hernia strangulates the tissue that pushes out, cutting its blood supply. If this happens surgical intervention should be done as quick as possible.
Umbilical hernia surgery succeeds in 99.99% cases, especially if the doctor's indications about the short recovery period that comes after the surgery are carefully followed .
Overall this illness is not dangerous at all in most cases so there aren't any reasons to worry because it will most likely push back on its own. But if you suspect any complications visit a doctor as soon as you can.

A hernia occurs when the contents of a body cavity bulge out of the area where they are normally contained. These contents, usually portions of intestine or abdominal fatty tissue, are enclosed in the thin membrane that naturally lines the inside of the cavity. Although the term hernia can be used for bulges in other areas, it most often is used to describe hernias of the lower torso (abdominal wall hernias).
In medical terminology, many terms are used such as bulging disc, pinched nerve, slipped disc or ruptured disc to describe herniated disc. Spine damage caused by disease, injury or normal wear and tear can lead to herniated disc. Herniated disc condition is the result of inflammation of the disc material caused by aging and compression on the nerve system.
Thousands of patients experience ventral (incisional) hernias every year, and most of these hernias require hernial repair surgery. Many patients have questions about this complex medical procedure, and the different treatment options available to them. This article exists in an attempt to answer many of those queries.
