A colonoscopy is a diagnostic procedure that allows doctors to examine the digestive tract for potential issues like polyps, inflammation, or even cancer.
After the procedure, some people may experience bloating, stomach cramps, and changes in their digestive system that can last up to 1-2 days. Eating the right foods can help ease these symptoms and restore the digestive system while providing necessary nutrients.
Foods to Eat After a Colonoscopy
A colonoscopy involves inspecting the inside of the intestines, including the large intestine, rectum, and anus, with the help of an endoscope. This flexible tube with a camera is inserted through the anus, and it transmits images of the digestive system to a screen. The results will be evaluated.
Before the procedure, the intestines are cleaned, disrupting the natural balance of bacteria in the digestive system.
After the colonoscopy, the effects of anesthesia can lead to sensations of fullness and nausea. Some people experience bloating, stomach cramps, and changes in bowel movements. While these symptoms usually subside, they can make it difficult to eat or drink, increasing the risk of dehydration and making it harder to meet nutritional needs.
To help ease the transition back to normal eating and relieve discomfort, start with easily digestible foods in small portions. Some suitable options include:
-
Mashed potatoes
-
Bananas
-
Scrambled eggs without milk
-
Yogurt
-
White bread
-
Chicken soup
-
Pudding
-
White rice
-
Low-fat proteins like chicken, turkey, soft tofu, or fish
These foods are gentle on the digestive system and can help restore balance after a colonoscopy.
In addition to food, staying hydrated is crucial. Increasing fluid intake and eating foods with high water content can help prevent dehydration.
Some good fluid options include:
-
Water
-
Coconut water
-
Clear broths
-
Herbal tea
-
Electrolyte drinks
-
Apple juice
If your urine is dark yellow or brown, this could indicate dehydration. Increase your fluid intake by drinking water or eating soupy foods to help rehydrate.
Foods to Avoid After a Colonoscopy
There are no strict dietary restrictions after a colonoscopy, and you can enjoy a variety of foods. However, experts suggest avoiding foods that could trigger nausea, bloating, or stomach discomfort.
Triggers for bloating and nausea vary from person to person, but some foods to consider avoiding include:
-
High-fiber foods such as whole grains, raw vegetables, nuts, and seeds
-
Greasy, fatty, or fried foods like fried chicken, French fries, and burgers
-
Spicy or heavily seasoned foods
-
Raw vegetables or gas-producing foods like broccoli, cabbage, onions, or garlic
-
Red meats like steak
-
Dried fruits
Additionally, drinks that can cause bloating, such as carbonated beverages and caffeinated drinks, should also be avoided.
Since a colonoscopy can temporarily alter your digestive function, leading to bloating or cramping, a doctor or nutritionist will be able to provide a suitable diet plan. If you have questions about health and nutrition, you can use the consultation feature on the Ai Care app, available for download from the App Store or Play Store.
