During Colonoscopy

Even though a colonoscopy is relatively painless, you’ll receive an intravenous sedative prior to the exam that will make you feel drowsy and help you relax. Throughout the exam, your heart rate and blood pressure will be carefully monitored. You’ll be asked to lie on your left side when the colonoscope (a flexible camera) is inserted into your rectum and advanced through your entire colon. At this point, the colonoscope is gently withdrawn and a detailed examination begins. If Dr. Singh has difficulty seeing some parts of your colon, he may inflate your colon with air or wash the lining with water to improve the quality of images of your colon’s lining. Should Dr. Singh detect a polyp or an abnormal growth during the examination, he may remove it or take a biopsy for laboratory testing. The usual duration of a colonscopy is 15-30 minutes.

After Colonoscopy

Even though the sedative will wear off quickly, you will need a ride home. You cannot drive after the colonoscopy. Due to the placement of the IV, the sedation, and the need to monitor you after the procedure, you will be at the surgery center for approximately 3 hours. A friend or relative can stay with you or come back to pick you up. You shouldn’t make any important decisions for the rest of the day either. It’s best to just go home and rest.

You may experience some temporary bloating, which can be relieved by walking and should resolve as you pass gas over several hours. This is normal and not a cause for alarm. You may also notice a small amount of blood in your stool following your colonoscopy. It is normal. Should you, however, continue to bleed or develop persistent pain or fever, contact Dr. Singh immediately.
