What is a Colonoscopy for?
A colonoscopy is an endoscopic examination of the colon and rectum that helps detect and treat:
- Polyps and colorectal cancer
- Bleeding, anemia, abdominal pain, bowel movement disorders
- Monitoring of inflammatory bowel disease (IBD)
- Follow-up after polyp removal or with family history
- Duration: 30 to 45 minutes
- Light sedation possible (if needed)
- An endoscope is inserted through the rectum to visualize the mucosa; biopsies and polyp removal can be done during the same session
- Short recovery period in the recovery room
Preparation (essential)
- Low-residue diet 24–48 hours before the exam
- Bowel cleansing (prep laxative) the day before — often with a “split dose” regimen
- Fasting according to instructions provided
- Medications: adjustment of anticoagulants/antiplatelets under medical advice; bring a full list of your medications
- Transport: if sedation is given, arrange for an escort and do not drive the same day
After the exam
- Bloating and gas may last a few hours
- Gradual return to diet according to instructions
- Light bleeding may occur after biopsy/polyp removal
- If you experience significant pain, fever, or heavy bleeding: seek medical attention immediately
Results and Follow-up
- Preliminary report provided the same day
- Pathology (biopsy) results sent as soon as available, with follow-up plan
- Screening interval: depends on risk profile and results (often every 5–10 years if normal)
Risks (rare)
- Bleeding (especially after polyp removal)
- Perforation
- Reaction to sedation
➡️ The physician will assess the benefit/risk according to your case
Alternatives
- Virtual colonoscopy (CT colonography): useful if colonoscopy is incomplete or contraindicated, but does not allow biopsies or polyp removal
Costs and Insurance
- Fees vary depending on the procedure (exam alone, biopsies, polyp removal)
- Receipt provided for reimbursement
