Why might a colonoscopy be recommended?
Colonoscopy examines the large bowel using a flexible camera. It may investigate bleeding, anaemia, bowel symptoms or inflammation, or be used for screening or surveillance when appropriate. Tissue samples and suitable polyps may be removed during the procedure.
Good preparation matters
Follow the specific food, fluid and bowel-cleansing instructions given to you. Poor preparation can hide abnormalities or lead to a repeat procedure. Tell the team if you cannot complete the preparation, become unwell or have concerns about fluids, kidney disease, diabetes or your medicines.
Consent and medicine planning
Discuss sedation, the possibility of polyp treatment, alternatives and risks such as bleeding, perforation and medicine reactions. Do not stop anticoagulants or adjust diabetes treatment on your own. Arrange a companion when required and follow the driving restrictions given after sedation.
After the test
Ask whether the examination was complete, whether the preparation was adequate, and whether biopsies or polyps were taken. Follow-up depends on the full report and laboratory findings, not simply the fact that a polyp was found. Significant bleeding, severe or increasing pain, fever or fainting needs urgent assessment.
Questions for your visit
Bring previous colonoscopy and pathology reports. Ask how you will receive your results, who will discuss them and when a further review is due. Tell the clinician about bowel cancer or polyps in your family. Screening and surveillance plans should be based on individual risk rather than copied from another patient.
