What to expect from colonoscopy for Lynch syndrome

Lynch syndrome is an inherited condition that raises the chance of certain cancers, including cancer in the large bowel. Colonoscopy allows a specialist to inspect the entire colon for polyps, irritated areas, or other changes. A flexible scope enters through the rectum while you lie on your side. Polyps can sometimes be removed and sent to a laboratory. The report may describe their location, size, and appearance; laboratory results then help determine the next step in your personal monitoring plan.

Use the bowel-preparation instructions supplied by your clinic, including the timing of clear fluids and the cleansing medicine. Give the team a complete list of prescriptions, supplements, allergies, and previous reactions to sedation. Confirm whether a medicine such as an anticoagulant needs special instructions. Sedation can affect alertness, so organise transport and follow the discharge advice. Before leaving, check how and when you will receive results and who will coordinate future surveillance.

Seek medical advice urgently if you develop severe or increasing abdominal pain, persistent vomiting, fever, fainting, breathing difficulty, or heavy rectal bleeding. If a biopsy or polyp removal was performed, ask the unit what bleeding pattern is expected and which number to call outside normal hours.

Ask how often your team recommends colonoscopy, whether sedation is appropriate for you, what happens if a polyp is found, when pathology will be reported, and whether relatives should receive genetic counselling.
