Preparing for a Scheduled Colonoscopy

June 13, 2008
Readers:

In the days before a scheduled colonoscopy, prepare for the exam by avoiding red, orange and purple foods and beverages, which can look like blood during the screening.

Ask ahead about taking regular medications. For instance, if you take insulin, ask about special instructions to help prevent hypoglycemia. If you regularly take aspirin, ask your colonoscopy doctor if discontinuing aspirin before your test may be worthwhile and, if so, for how long. Talk with your primary care provider if you take an anticoagulation drug such as warfarin (Coumadin) or clopidogrel (Plavix), as frequently these must be discontinued or monitored before a colonoscopy. Stop taking oral iron supplements at least five days before the procedure.

To help gear up your digestive tract for cleansing:

• Lighten your diet — Avoid high-fiber food for two to three days before your preparation day. Reduce portions.
• Stock up on clear liquids — A clear diet is recommended for 24 hours before a colonoscopy. Good choices include water, clear broth, fruit juices without pulp, and clear, colorless sodas.
• Serve it cold — You may find the colon prep solution more drinkable if it's cold. Prepare and refrigerate it according to package directions.
