Hernia (C0019270)

Definition (MSH) Protrusion of tissue, structure, or part of an organ through the bone, muscular tissue, or the membrane by which it is normally contained. Hernia may involve tissues such as the ABDOMINAL WALL or the respiratory DIAPHRAGM. Hernias may be internal, external, congenital, or acquired.
Definition (MEDLINEPLUS)

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.

There are several types of hernias, including

  • Inguinal, in the groin. This is the the most common type.
  • Umbilical, around the belly button
  • Incisional, through a scar
  • Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
  • Congenital diaphragmatic, a birth defect that needs surgery

Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.

Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.

Definition (NCI) The protrusion of part of an organ or fibroadipose tissue through an abnormal opening.
Definition (NCI_NCI-GLOSS) The bulging of an internal organ through a weak area or tear in the muscle or other tissue that holds it in place. Most hernias occur in the abdomen.
Definition (CSP) protrusion of a loop or knuckle of an organ or tissue through an abnormal opening.

Definition (NCI) The protrusion of abdominal contents through a congenital or acquired defect in the abdominal wall.
Definition (MSH) A protrusion of abdominal structures through the retaining ABDOMINAL WALL.
