In children, an excessive natural weakness can lead to a hernia. In adults, a natural weakness or straining from heavy lifting, substantial weight gain, persistent coughing or difficulty with bowel movements or urination can cause the abdominal wall to tear. When a hernia in the groin occurs because of a natural weakness, it is called an indirect inguinal hernia. If it is caused by excessive strain, it is called a direct inguinal hernia. Hernias may also be found below the groin, through the navel, and along a previous incision.
Surgical repair is the only way to repair a hernia.
With traditional hernia repair a 3-5 inch incision is made in the groin. The hernia sac is removed and the opening is closed by sewing the edges together or by attaching a mesh patch to the outside of the abdominal wall. With an innovative new technique called laparoscopic surgery, hernia repair is now possible in a minimally invasive manner. With laparoscopic surgery the mesh is attached inside the abdominal wall. This method works with the natural outward pressure of the abdomen to secure the repair.
