A hernia is when some organ or tissue of the body leaves its normal site and enters another site through a weak point or defect that is formed congenitally or acquired. Hernias are commonly found in umbilical hernia, inguinal hernia, hiatal hernia, incisional hernia, hernia after surgical recurrence, white line hernia and femoral hernia. A hernia in the abdominal wall is equivalent to a sudden increase in intra-abdominal pressure caused by an increase in abdominal pressure, such as when coughing, sneezing, overexertion or straining to defecate, or even when pregnancy or a small child cries, when the abdominal wall is weaker in the elderly, forcing the free organs in the abdominal cavity to protrude through the weak area to the surface of the body and into another part, which is called a hernia. Hernia can only be treated surgically, similar to a hole in a garment, a patch is made to the weak area, so that the area that could protrude before cannot protrude.
