Diabetes: How to Prepare for a Colonoscopy - Topic Overview

What is a colonoscopy?

A colonoscopy is a test that lets a doctor look inside your colon. The doctor uses a thin, lighted tube called a colonoscope to look for small growths (called polyps camera.gif), cancer, and other problems like bleeding.

During the test, the doctor can take samples of tissue that can be checked for cancer or other problems. This is called a biopsy. A colonoscopy also lets the doctor take out polyps.

Did You Know?

Under the Affordable Care Act, many health insurance plans will cover preventive care services, including checkups, vaccinations and screening tests, at no cost to you. Learn more.

Before the test, you will need to stop eating solid foods. You also will drink a liquid or take a tablet that cleans out your colon. This will help your doctor to be able to see inside your colon during the test.

Before you schedule

When you make your appointment for the colonoscopy, mention that you have diabetes. Ask for any special instructions. Request an early morning appointment so you can get back as soon as possible to your normal routine for eating and taking medicines.

The doctor doing your colonoscopy (gastroenterologist) will want to know about all the medicines you take. Be sure to also tell him or her about any vitamins, supplements, and herbal remedies you take. It's a good idea to have a list of all your medicines when you make your appointment.

If you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, your doctor will tell you if and when you should stop taking these medicines before your test.

Before the procedure

Talk with your diabetes doctor about how best to manage your blood sugar before and after the test.

Arrange to stay home on the day of the test. When you use the liquid or pills to clean out your colon, you will go to the bathroom a lot. You'll get detailed instructions from the doctor on how to use the medicines (colon prep).

Discuss with your doctor the different types of medicines. You may need a type that is safest for people with kidney problems.

Stop drinking alcohol at least 1 day before and 1 day after your procedure. Alcohol could cause a strong reaction with the anesthesia medicines used during the test.
