Can I eat 24 hours before a colonoscopy?
24 hours before. No matter your diet in the days before your colonoscopy, you must switch to a liquid-only diet 24 hours before your exam. You can eat and drink any clear liquids you want, but a good rule of thumb to follow is eight ounces per hour that you're awake.
Here are some examples of foods that you can eat on the days leading up to your colonoscopy:
- Milk, cheese, yogurt, sour cream.
- White rice, white bread, refined pasta, refined crackers, breakfast cereals.
- Applesauce, canned vegetables, fruits without seeds or skin.
- Chicken, pork, seafood.
- Generally, if you take: Metformin, your doctor may have you stop taking it 48 hours before and after your colonoscopy. Diabetes medicine other than insulin, your doctor may have you stop taking your medicine on the morning of the test.
- One day before the colonoscopy: begin the colon prep as detailed below. 2) At 1PM take 3 tablets of dulcolax laxative pill with water by mouth. 3) At 3 PM drink half the Gatorade / Miralax / Mylicon solution. Drink one 8 ounce glass every 15 minutes.
- Tea and black coffee without any milk, cream, or lightener. Flavored water without red or purple dye. Clear, light colored juices such as apple, white grape, lemonade without pulp, and white cranberry. Clear broth including chicken, beef, or vegetable. Soda.
Do not eat nuts, seeds, popcorn or corn. On the day before the procedure: Have only clear liquids (broth, clear soups or beverages, transparent juices, Jello and popsicles) until 4 hours before the procedure the next day. HAVE NOTHING TO EAT OR DRINK AFTER THAT.
- DAY BEFORE YOUR COLONOSCOPY: The day before your colonoscopy, you may only drink clear liquids. This includes clear soda, sports drinks, broth and juice without pulp. This means no gum, no mints, no hard candy, no cigarettes and no additional liquids.
- Food And Drink Not Allowed. What is not allowed prior to a colonoscopy is milk, soy milk, creamer, or any other dairy product. These should not be taken in coffee or tea before a colonoscopy. Depending on the time of the test, even clear liquids must be discontinued a few hours prior to the colonoscopy.
- Patients without health insurance typically pay $2,100 to $3,764, according to CostHelper.com. The average colonoscopy cost is $3,081. Patients with health insurance pay deductibles based on their plan. Deductibles range from zero to more than $1,000.
Clear liquids include anything that you can see through including; beef, chicken, vegetable broth or bouillon, apple juice, white grape juice, white cranberry juice, sodas (colas or clear, diet or regular), Jell-O or popsicles (green or yellow only), and coffee or tea.
- Plain gelatin is a clear, unflavored gelatin suitable for use in your diet. You may use it to replace flavored gelatins, to thicken sauces or to make food molds such as aspic. It is available in your local grocery store in the same section as flavored gelatin powdered mixes.
- Clear soup is sometimes part of a hospital diet, or it is used to help squelch your appetite when dieting. Understanding what a clear soup actually is helps you properly adhere to a clear liquid diet and avoid complications. Clear soups are often a base for more complex soups, stews and sauces.
