Post-Gastrectomy Diet

This diet is designed for patients to follow after a gastrectomy (stomach surgery).

Important points to keep in mind

  • Your body needs added calories and protein to help heal itself. Start slowly and
    gradually eat more as you are able.
  • Eat small, frequent meals at least six times per day. See sample menu on a following
    page.
  • Everyone tolerates foods differently. Avoid those foods known to cause you problems.
  • Keep high-calorie snacks handy, such as cheese, peanut butter crackers, and yogurt.
  • Pack extra protein into foods by adding shredded cheese, dry milk powder, or peanut butter.
  • Drink only nutritious beverages. Try milk, eggnog (without alcohol), or unsweetened juice instead of coffee, tea, diet soda, or water.
  • Report any weight loss to your doctor.

About dumping syndrome

When food or fluids move too quickly through your digestive system, it’s called “dumping syndrome.” Symptoms of dumping syndrome are:

  • nausea
  • dizziness or light-headedness
  • weakness and fatigue
  • rapid pulse
  • abdominal cramping
  • diarrhea

It’s very important to tell your doctor if you have any of these symptoms.

Here are some tips to help avoid dumping syndrome:

  • Don’t drink liquids with your meals. Wait one-half to one full hour after eating solid food to drink something.
  • Limit sweets. Use sugar-free foods and drinks in place of regular sweet foods or drinks.
  • Lactose (milk sugar) may also cause diarrhea and cramping. Drink lactose-free or lactosereduced milk, or take lactase enzyme tablets (like Dairy Ease) when you eat dairy products.
  • Adding extra fats (like butter, margarine, cheese, gravy, cream, or sour cream) to foods may help slow down the movement of food through your system.
  • Avoid extremely hot or cold foods.
  • Avoid carbonated drinks and alcohol.
  • Eat slowly and chew your food carefully.
