Diverticular Disease


  • Diverticula: pouches in bowel wall (a defect in the bowel wall continuity), usually from 0.5 – 1cm
  • Diverticulosis: the presence of diverticula without symptoms
  • Diverticulitis: inflammation of diverticula
  • Often described to patients as “wear and tear of the bowel”



  • Very common as people age
  • Low fibre diets and obesity are risk factors
  • Often diagnosed incidentally on colonoscopy or CT scan
  • No treatment necessary, but advice regarding high fibre diet and weight loss is appropriate
