Foods to avoid
Spicy food should be avoided after a colonscopy.
Although a colonoscopy procedure does not take very long, the colon needs time to recover from the procedure itself and the preparation for it.
So, for a day or so following a colonoscopy, it is advisable to avoid foods that are hard to digest, such as high fiber and spicy foods.
It is also a good idea to avoid heavy, fatty foods as they can cause nausea and vomiting after anesthesia.
If another procedure, such as the removal of a polyp, has also taken place, a doctor may recommend further food restrictions. These include foods containing small seeds, kernels, and nuts as these small, hard particles can get trapped in the healing wound and cause infection.
During a colonoscopy, gas is blown into the colon to open it up and allow better visibility during the colonoscopy. After the procedure, this excess gas may be uncomfortable, and a person may feel the need to pass gas more frequently.
Because of this, a person may choose to avoid foods that cause additional gas, such as beans or carbonated beverages.
Avoid the following after a colonoscopy:
- spicy or well-seasoned foods
- whole or chopped nuts
- fried foods, such as chicken fingers and french fries
- raw or undercooked vegetables
- brown rice
- crunchy nut butters
- whole grain bread and baked products
- tough proteins, such as steak
- fruit with skin, such as apples
