How to Prepare

Most people should get screened for colon cancer no later than age 50. Before the procedure, it is essential to clear your colon of solid waste before your colonoscopy adequately. Use the prescribed laxatives to bring on bowel movement. If your colon is not entirely cleared, your doctor may not get a clear view. In such cases, the procedure may be rescheduled or stopped. It will cause a delay in diagnosis and treatment.

Your physician may advise you to take or avoid certain medications before your procedure, depending on your situation.

What to Expect

Colonoscopy takes about 10-20 min and is usually performed as a day surgery procedure. Before it starts, you will be given mild sedation to relieve any potential discomfort. You will lie on the side, and your knees tucked into your body. During the procedure, the doctor will insert the endoscope into your colon through your anus. Additional procedures, such as biopsies and polyp removal, may be performed if necessary.

After the procedure end, we will move you to the ward for observation until the sedation wears off. You will serve you light refreshments, and the specialist will visit you to explain the results at the bedside. If the screening is normal, you will be discharged.

We have introduced artificial intelligence (AI) assisted colorectal screening to help improve detection, classification, screening, and surveillance for colorectal polyps and cancer. Learn more.
