My doctor explained that i have an umbilical hernia. what does this mean?

Abd Wall Weak Point: An umbilical hernia is a weak point in the tough connective tissue of the abdominal wall that allows the abdominal contents to protrude during activities that lead to increased intra-abdominal pressure such as straining. This can be corrected with a surgical procedure usually involving a synthetic mesh patch sutured over the defect.

Weak Point in Navel: A hernia occurs when tissue bulges out through an opening caused by a weakness in the muscles of your abdominal wall. Most commonly the contents that bulge out through this opening are your intestines or intra-abdominal fat. When this weakening and opening occurs in the belly button, it is called an umbilical hernia. Surgery is the only way to fix a hernia.

Weak point in navel: You have a defect at the navel where your umbilical cord was attached. This defect normally closes by the age of 2. However, in some patients this defect can enlarge over time. Usually the defect is manifested by a bulge at the navel. Sometimes, the abdominal contents in the hernia can become trapped at the muscle (incarcerated hernia) and cause pain that will require repair.

Abd Wall Weak Point: An umbilical hernia is an opening in the abdominal wall where the belly button is located. It is possible for contents inside the abominal cavity (such as intestines) to protrude through that opening. These hernias usually require surgical repair to prevent incarceration or strangulation, where the intestines protrude and get stuck.
