There is only so much that can be done to manage or prevent bowel obstructions, especially in patients who have undergone extensive abdominal surgeries such as CRS/HIPEC. However, some lifestyle and dietary strategies may help reduce risk and support overall digestive health:

• Hydration: Staying well-hydrated helps maintain a healthy water balance in your bowels, allowing stool to remain soft and move more easily through the intestinal tract.

• Smaller, more frequent meals: Eating smaller portions throughout the day reduces the workload on the digestive system and can help prevent blockages.

• Chew food thoroughly: Proper chewing breaks down food into small pieces, making digestion easier.

• Monitor intake of high-fiber foods: While fiber is generally healthy, it can bulk up stool and may increase the risk of blockage in patients with narrowed or sensitive bowel areas. Avoid foods with skins, seeds, husks, or fibrous textures.  

• Consistent physical activity: Gentle, regular movement can help stimulate digestion and promote healthy bowel function.

 

For some patients who face recurrent bowel obstructions, a care provider may recommend an ostomy to relieve symptoms, reduce risk of bowel damage as a result of obstructions, and improve quality of life. 

 

Dietary Considerations

Foods to Avoid:

These foods are more difficult to digest and may increase the risk of bowel obstruction:

• Raw vegetables, especially stringy ones like celery or cabbage

• Corn, popcorn, nuts, and seeds

• Dried fruits

• Skins of fruits and vegetables (e.g., apple peel, grape skin)

• Legumes (beans, lentils) due to their tough skins and high fiber

• Tough or gristly meats

 

Foods to Eat:

These are generally easier to digest and less likely to cause blockages:

• Well-cooked vegetables in limited quantities (peeled and pureed if needed)

• Canned fruits or peeled, soft fresh fruits in limited quantities (e.g., bananas, melon)

• White bread, refined cereals, and pasta

• Tender meats, fish, poultry (without skin or bones)

• Eggs, dairy products, smooth nut butters (if tolerated)

• White rice, plain potatoes (without skin)

 

In Case of Partial Obstruction Symptoms

(Symptoms may include cramping, bloating, nausea, or changes in bowel habits)

If symptoms of a partial bowel obstruction occur, temporarily switch to a liquid or low-residue diet, limiting intake of high-fiber foods and dairy-based foods. This helps reduce the amount of material moving through the bowel, easing pressure on the intestines and giving the body a chance to recover. Recommended options include:

• Clear broth

• Heavily pureed foods

• Juice without pulp

• Gelatin

• Tea

• Electrolyte drinks

Avoid high-fiber and most dairy products during this time, as they can increase stool bulk and worsen symptoms.
