Occurring mostly in infants, a part of the fatty tissue projects through the umbilical opening near the navel. A small pouch is evident in the inner lining of the abdominal cavity when the contents push through it. Umbilical hernias are fairly common in premature babies. As the foetus develops, under normal conditions, the umbilical cord passes through the opening in the abdominal wall closes before the child is born. When the muscles do not seal completely, they leave a weak spot where an umbilical hernia can develop. Laughing, crying, heaving and coughing make a hernia more apparent. Umbilical hernias are painless and often do not cause any discomfort. In adults umbilical hernia is common in women after multiple child births. The abdominal wall becomes lax and the umbilicus becomes more prominent.
In children: A bulge of approximately 1 to 5 cms in diameter near the navel; no symptoms are noticed when the baby is relaxed
In adults: Painful swelling or bulge near the navel
More serious symptoms in infants:
Congenital umbilical hernia: A congenital or birth malformation of the umbilicus; common in children as well as in adults
Acquired umbilical hernia: Umbilical hernia as a result of heavy lifting, obesity, history of multiple pregnancies, chronic coughing
Paraumbilical hernia: Hernias involving the protrusion of the abdominal contents along with the mesenteric fat through a weakness near the navel
Surgical intervention is advised in adults if a hernia causes pain and discomfort. If a hernia does not show any signs of reducing by itself, surgery is always recommended to avoid potential complications. Umbilical hernia repairs are carried out with mesh placements for patients with defects > 4 cm and recurrent hernias. Surgery is under general anaesthesia. It can be done either open or through keyhole.
We look for signs of reduction in infants by about 1 to 2 years of age, after which he offers a consultation for treatment of infantile umbilical hernias. For adults, we prescribe surgical intervention to avoid possible complications, especially in women.Authored by Dr. Deepak Varma, MBBS, MS (General Surgery)
