A hernia is the extension of an organ or fatty tissue through a weak spot in the muscle or connective tissue that surrounds it. It can occur in the groin (inguinal or femoral hernia), belly button (umbilical hernia), and upper stomach (hiatal hernia) or at the region of a previous incision (incisional hernia).
All hernias do not require treatment but may be monitored for possible complications. Surgery is recommended when your hernia causes pain and enlarges. It is considered a medical emergency when the organ becomes trapped and strangulated cutting off the blood supply to the tissues.
