An inguinal hernia is an abnormal bulge of a section of intestine and fluids in the groin region. In children, an inguinal hernia is present from the time of birth. It is caused by a weakened spot in the abdominal wall when an opening in the wall does not normally close before birth.
A femoral hernia is a bulge that forms when a part of the peritoneal sac (abdominal wall), consisting of fatty tissue, intestine or other structures, protrudes and is visible just below your lower abdomen and upper thigh, near your groin crease or labia (skin folds around the vagina).
A hernia is an abnormal opening in the wall of a tissue, muscle or membrane that holds an organ in place. The stomach lies below the diaphragm. Hiatal hernia is a condition in which part of the stomach slides through the hiatus, an opening in the diaphragm, and protrudes into the chest.
