A colonoscopy lets your doctor examine the large intestines (colon) to find out the cause of bowel-related issues.
Colonoscopes have several hollow channels for suction, air & water delivery and biopsy taking and the examination uses a flexible fibreoptic camera inserted through the anal canal into the large intestine.
- Lower gastrointestinal tract bleeding, blood in stool
- Acute and chronic diarrhoea
- Screening and surveillance of colorectal polyps and cancers
Colonoscopy is a safe procedure.
There is a minimal risk of bleeding or perforation (tear in the bowel). Fewer than 0.001% of people experience bleeding or perforation.
A low fiber diet is prescribed before the exam. Fasting is required for at least 8 hours before the exam.
Laxative is given to cleanse the bowel.
Inform your doctor if you are on any anti-coagulants, anti-platelets or blood thinners.
What you can expect
It takes about an hour to recover from the sedation. You will need someone to take you home because it can take up to a day for the full effects of the sedative to wean off. Do not drive, make important decisions or go back to work for the rest of the day
Bloating and passing wind are common occurrences after the procedure. Walking may help to relieve any discomfort.
If a biopsy or polypectomy was performed, you may notice a small amount of blood in the first bowel movement after the exam. Usually this isn’t a cause for alarm.
- You are encouraged to start your diet by sipping water or cool liquids and having soft food. You can resume your normal diet once you feel better.
- In some instances, you may not have fully recovered from the sedation. You are NOT encouraged to drive, operate heavy machinery, drink alcohol, conduct business or sign legal documents.
- You are advised to go home and REST.
- If you have problems, go straight to the hospital for further assessment.
