What To Eat After A Colonoscopy? Eat This, Not That!

What To Eat After A Colonoscopy

A colonoscopy, a medical procedure that allows doctors to inspect the large intestine for signs of colorectal cancer and other conditions, can be a life-saving diagnostic tool. While this procedure is essential for many, understanding its impact on your digestive system and how your diet should adapt in the aftermath is equally important. This article will delve into what to eat after a colonoscopy, shedding light on the importance of specific dietary choices and how they can promote a healthy colon and support recovery.


How A Colonoscopy Procedure Affects Your Digestive System


A colonoscopy can temporarily disrupt the normal functioning of your digestive system. To enable a clear view of the colon and rectal areas, patients are usually placed on a clear liquid diet before the procedure. This diet, coupled with laxatives, effectively empties the colon but can leave the digestive system somewhat ‘unsettled’. It is, therefore, essential to gradually reintroduce foods following a colonoscopy to allow your digestive tract to regain its normal function.


Recommended Foods To Eat After A Colonoscopy

After the procedure, the goal is to eat soft foods on the digestive system. Nutritionists often recommend starting with a low-residue diet. This diet includes foods that are easy to digest and less likely to cause discomfort. Examples of these include:

  1. Soup: Broth-based soups are gentle on the stomach and can help with rehydration.
  2. Yoghurt: This is a soft food that is easy on the digestive system and contains probiotics that can aid in restoring gut health.
  3. White Bread and Mashed Potatoes: These are examples of easily digestible, low-fibre foods. While whole-grain bread and other high-fibre foods are usually recommended for a healthy diet, they may be too rough on the digestive system immediately after a colonoscopy.
  4. Scrambled Eggs: Eggs are an excellent protein source that can be gently reintroduced into the diet.
  5. Water: Hydration is crucial after a colonoscopy. Drinking plenty of water aids in rehydration and helps the digestive system return to normal functioning.
  6. Drinks with Electrolytes: Sports drinks containing electrolytes can assist in replenishing those lost during the procedure, making them a suitable choice after a colonoscopy.
  7. Vegetable or Fruit Juice: These can be a good source of hydration and nutrients, but it’s advisable to opt for low-fibre choices.
  8. Herbal Tea: Often containing ingredients that can soothe the digestive tract, herbal tea can gently rehydrate after a colonoscopy.
  9. Popsicles: These contain both sugar and liquid, which can help increase energy levels post-procedure.
  10. Crackers: Easy-to-digest options like Saltines and graham crackers can be consumed following a colonoscopy.
  11. Smooth Nut Butter: Nut butters are generally easy to digest. Choose smooth varieties over chunky ones to avoid irritating the digestive system.
  12. Applesauce: This is an excellent choice as it contains easily digestible fibre and can help restore energy levels.
  13. Gelatin or Pudding: These options are recommended after a colonoscopy due to their soft texture and easy digestibility.
  14. Canned or Jarred Fruit: Soft, peeled fruits like peaches or pineapples are a good choice. Avoid fruit with the skin.
  15. White Toast: Like white bread, white toast is a bland food that can be safely consumed for a few days following a colonoscopy.
  16. Cooked Vegetables: Well-steamed, baked, or sautéed vegetables cooked until tender are a suitable choice following a colonoscopy. However, fibrous vegetables should be avoided.
  17. Chicken: Lean proteins like chicken can be reintroduced into the diet following a colonoscopy.
  18. Rice: Cooked white rice is gentle on the stomach and can be a part of the diet following a colonoscopy.
  19. Pasta: Like rice, pasta is easy to digest and can be consumed after the procedure.
  20. Fish: Fish, especially white fish, is typically soft and digestible, making it an appropriate choice after a colonoscopy. It’s advisable to avoid bony or fatty fish.


Consulting With Your Doctor Or Dietitian

While this guide provides general advice about dietary choices post-colonoscopy, discussing your dietary plan with your doctor or dietician is essential, especially if you’re on a restricted diet or have certain health conditions like Crohn’s disease. Everyone is unique, and the most suitable dietary choices often depend on your health history and any specific dietary needs or restrictions.


Conclusion On What To Eat After A Colonoscopy

Your digestive system requires time to recover following a colonoscopy screening. Careful dietary choices are paramount, focusing on foods that are easy on the stomach whilst avoiding those that could lead to discomfort or complicate recovery. Remember, whilst this guide offers general advice, it’s always wise to consult with your doctor or dietician, particularly if you have specific health concerns or dietary restrictions.


Frequently Asked Questions On Foods To Eat After A Colonoscopy

Can I Eat Greasy Foods Post-Colonoscopy?

It’s best to avoid greasy and fried foods immediately after a colonoscopy as they can be harder to digest and cause discomfort. Once your digestive system is back to normal, you can gradually reintroduce such foods as tolerated.

What Helps Stomach Pain After Colonoscopy?

Drinking plenty of water, eating soft and easily digestible foods, and avoiding high-fibre, spicy, and fatty foods can help alleviate stomach pain after a colonoscopy. If the pain is excruciating or persists, consult a colorectal surgeon.

Can Certain Foods Cause Colorectal Cancer?

While no single food can cause colorectal cancer, a long-term diet high in processed meats and low in fruits, leafy greens, and whole grains can increase the risk. A balanced diet is vital for colon health.

Is Eating Rice Okay After A Colonoscopy?

Yes, eating rice, mainly white rice, is okay after a colonoscopy. It’s gentle on the digestive system and can be part of your post-procedure diet.

How Many Days Of Rest Should I Get After A Colonoscopy?

You need one day of rest after your colonoscopy, but some may need more time. However, your doctor will advise that it’s generally fine to resume your usual activities the following day. Always follow your doctor’s instructions.

Are Raw Fruits And Vegetables Okay After A Colonoscopy?

Directly following a colonoscopy, your doctor may recommend avoiding raw fruits and vegetables as they are high in fibre and can be difficult to digest.

What Should I Eat After A Colonoscopy With Polyps Removal?

If you’ve had polyps removed during your colonoscopy, it’s advisable to follow a gentle diet similar to a standard post-colonoscopy diet. This includes easy-to-digest foods like broth-based soups, white bread, scrambled eggs, and mashed potatoes. As your digestive system recovers, you can progressively include more diverse foods, but always follow the guidance of your healthcare professional.
