Hernia is a defect in the sheath or muscle of the abdominal wall, due to this defect abdominal contents protrude into the superficial space of the abdomen. It occurs either through the natural openings like Inguinal Canal or Femoral canal or it occurs due to the weakness of the sheath or the abdominal musculature. Eg. Ventral Hernia.
Hernia may either be present in a person from the time of his birth or a person may acquire it during his lifetime due to certain living or working conditions.
