      2. Paraumbilical
      3. Epigastric
      4. Incisional
      5. Femoral
      6. Inguinal
         
    2. Less common

Inguinal hernias

  1. Contributory factors
    1. Congenital weakness
    2. Chronic straining factors - chronic constipation, bladder problems, occupational weight lifting, pregnancy.
       
  2. Types
    1. Indirect - containing structures from within the abdomen
      e.g. bowel, bladder
    2. Direct - mechanical weakness in the inner rear wall of the groin.
    3. Contents - can be fat, small bowel, large bowel, appendix
       
  3. Complications (can be potentially life-threatening)
    1. Irreducibility (‘reducible’ implies the protruding contents can be
      pushed back in).
    2. Obstruction - when bowel is locked inside the hernia
    3. Strangulation - when bowel dies within the hernia
