What Is A Colonoscopy?

What Is A Colonoscopy?

A colonoscopy is a medical procedure used to examine the inside of the large intestine (colon) and rectum. It involves using a long, flexible tube with a camera and light attached to it, called a colonoscope, to view the lining of the colon. The procedure is typically done to screen for colorectal cancer or diagnose intestinal issues such as polyps, ulcers, or inflammation. It is also a way for doctors to monitor and treat certain conditions, such as inflammatory bowel disease (IBD).

Immediately After Procedure (First Day)

In the first 24 hours following your colonoscopy, the three key rules are: start slow, avoid certain foods, and stay hydrated.

Starting slow

When you first begin eating again, go easy on your digestive system by starting with clear liquids:

  • Water
  • Clear broths (chicken, vegetable, beef)
  • Clear juices (apple, white grape, lemonade)
  • Popsicles
  • Gelatin

After tolerating clear liquids without issues, slowly introduce blander, more easily digestible foods:

  • Crackers
  • Applesauce
  • White bread or toast
  • Soup

Avoiding specific foods

Right after your colonoscopy, you’ll want to avoid foods that may cause gas or digestive discomfort, including:

  • Dairy products
  • Very sugary foods and drinks
  • Spicy foods
  • Fatty or fried foods
  • Tough meats or meats with a casing (like sausage or hot dogs)
  • Raw fruits and vegetables

Stick to low-fiber foods at first to give your colon time to heal. High-fiber foods like whole grains, beans, nuts, seeds, and many raw veggies can be reintroduced after a couple days.

Staying hydrated

Be sure to drink plenty of fluids like water, diluted juices, or electrolyte-rich sports drinks. Staying hydrated is key to recovering quickly and avoiding constipation.

Moving Forward (1-2 Days Later)

After the first 24 hours, you can slowly transition to a low-residue diet as your colon continues healing. Follow your doctor’s instructions on how long to maintain this type of diet.

Low-residue diet recommendations

A low-residue diet limits foods that could irritate or overwork your healing colon. Recommended foods include:

  • White bread or toast
  • Pasta, white rice
  • Cooked vegetables without skins or seeds
  • Canned fruits like peaches, pears, fruit cocktail
  • Tender meats like chicken or fish
  • Mashed potatoes
  • Creamy peanut butter
  • Eggs
  • Yogurt


  • Whole grains and bran
  • Raw fruits and vegetables
  • Dried beans, corn, peas
  • Nuts, seeds
  • Popcorn
  • Carbonated beverages

Additional restrictions after polyp removal

If your doctor removed any polyps during your colonoscopy, they may recommend avoiding foods with small seeds (like tomatoes, cucumbers, strawberries, raspberries) for up to 3-5 days post-procedure. This allows polyp sites extra time to heal.

Long-Term Colon Health

While short-term dietary changes promote recovery after your colonoscopy, certain lifestyle factors impact your colon health over the long run.

Regular colon cancer screening

  • Colonoscopies every 10 years from age 45-75 help detect colon polyps or cancer early when treatment is most effective.
  • African Americans should start screening at age 45 due to higher risk.
  • Those with a family history may need earlier or more frequent screening.

Diet and nutrition

A diet rich in fiber, lean protein, fruits, and vegetables may reduce colon cancer risk, while limiting red meat, processed foods, sugary drinks, and excessive saturated fat.

Recommended foods:

  • Fruits: berries, citrus fruits, melons
  • Vegetables: leafy greens, cruciferous veggies like broccoli and cauliflower
  • Whole grains: oats, brown rice, quinoa
  • Nuts and seeds
  • Legumes: beans, lentils, peas
  • Lean protein: fish, skinless poultry, eggs, tofu
  • Low-fat dairy: milk, yogurt, cheese
  • Healthy fats: olive oil, avocados


  • Red and processed meat
  • Refined grains
  • Fried foods
  • High-fat dairy
  • Sweets and sugary drinks

Physical activity

Regular exercise reduces colon cancer risk. Aim for 150 minutes per week of moderate activity like brisk walking.


Smoking is a major risk factor for many cancers including colon cancer. Quitting smoking and avoiding secondhand smoke is key for colon health. Talk to your doctor about cessation aids.
