Ileostomy Diet: Foods to Eat & Avoid for Optimal Health

After ileostomy surgery (diversion of the ileum to an abdominal stoma), dietary adjustments help prevent dehydration, blockage, and nutrient deficiencies.

Key Principles

• Hydration: Drink 2–3 L/day (water, broth, electrolyte solutions); limit sugary/caffeinated drinks.
• Small, Frequent Meals: 5–6/day to reduce stoma output volume and gas.
• Chew Thoroughly: Aids digestion, prevents large particles causing obstruction.

Foods to Favor

• Refined grains: white rice, pasta, sourdough, oatmeal
• Cooked, peeled vegetables: carrots, squash, spinach, potatoes
• Ripe/cooked fruits: bananas, applesauce, melon
• Lean proteins: eggs, poultry, fish, tofu
• Healthy fats: avocado, olive oil, smooth nut butters

Foods to Limit or Avoid Initially

• High‑fiber/raw vegetables (corn, nuts, seeds, raw greens, skins)
• Tough meats, dried fruits, popcorn, coconut
• Spicy foods, caffeine, alcohol (may increase output)
• Dairy if lactose intolerant

Reintroduce fiber gradually over weeks. Individual tolerance varies—keep a food/symptom diary. Regular follow‑up with a dietitian and surgeon ensures nutritional adequacy and stoma health.
