Why your doctor may suggest a colonoscopy

A colonoscopy may be suggested by your doctor if you have: 

  • Abnormal barium x-ray or abnormal CT Colonography
  •  Bleeding from the bowel 
  •  Abdominal pain 
  • Family history of bowel cancer 
  • Alteration in bowel habit e.g. diarrhoea, constipation
  •  Occult (unseen) blood in the stool 
  • Anaemia
  •  Previous treatment for polyps, bowel cancer or colitis


Your colon must be completely empty of faecal material for the procedure to be thorough and safe. If it is not entirely clean certain areas may be obscured and the test may have to be repeated. Following the preparation, the return from your bowel should resemble urine (pale yellow). This will involve modifications to your diet. You will be given more specific instructions about this including a liquid diet for one to two days and the bowel preparation (laxative). Prior to your procedure it is important for your doctor to know your medical history and in particular any previous endoscopies. Bring a list of your current medication with you, together with any relevant x-rays or barium studies. Fully disclose any health problems you may have had as these may interfere with your colonoscopy, sedation or recovery. 

You should mention: 

  • An allergy or bad reaction to medicines or anaesthetics
  •  Taking medication to thin your blood including Warfarin, Dabigatran, Rivaroxaban, Aspirin or antiplatelet medication: e.g. Clopidogrel or Ticagrelor. Your doctor may ask you to stop taking these medications prior to your procedure or you may be given an alternative dose. 
  • Artificial hip or knee joints. 
  • Prolonged bleeding/clotting disorders or excessive bruising
  •  Diabetes – You must discuss this with your doctor or nurse before undertaking any period of fasting.
  •  Heart and lung problems including artificial heart valves and pacemakers.
  • Cardiac stents in the last 6 months. 
  • If you are pregnant or breast-feeding.
