What Is Colonoscopy?
A colonoscopy allows your gastroenterologist to directly examine the entire colon and rectum using a thin, flexible, high-definition camera. It's the only screening test that can detect and remove precancerous polyps in the same visit.
Why Is It Done? (Indications)
- Routine colon cancer screening starting at age 45
- Evaluating rectal bleeding or changes in bowel habits
- Investigating chronic abdominal pain
- Surveillance after prior polyps or IBD diagnosis
How to Prepare
Step 1
A prescribed bowel prep solution the day before
Step 2
A clear-liquid diet for 24 hours prior
Step 3
Arranging a ride home, since sedation is used
Step 4
Reviewing current medications with our team beforehand
How It's Performed
You'll receive sedation to keep you comfortable, then the gastroenterologist guides the colonoscope through the colon, examining the lining and removing any polyps found. The exam itself typically takes 20 to 45 minutes.
What Happens After (Recovery)
Brief rest as sedation wears off
Resume normal diet and activity
Results reviewed with your doctor
Most patients recover in our facility for 30 to 60 minutes as sedation wears off, then go home with a companion. Mild bloating or cramping is common, and normal diet usually resumes the same or next day.
Risks
- Mild bloating or cramping
- Rare bleeding, particularly after polyp removal
- Very rare risk of perforation
- Reactions to sedation, which are closely monitored
