What do gastric bypass patients eat?

When gastric bypass patients eat the wrong foods they will experience dumping syndrome. Some of the foods recommended for the patients are lean meat, eggs, low-fat dairy products, cooked cereals, dried beans and peas, fruits, vegetables, protein-rich fish, and poultry.

Foods rich in sugar and in fats are not exactly the friends of a gastric bypass patient, as among the adverse reactions caused, one is especially scary. Dumping syndrome occurs when the stomach contents pass too rapidly from the stomach to the intestines. In order to avoid dumping syndrome and to secure sustained weight loss, the diet of gastric bypass patients must be designed in accordance with several guidelines. Do not hesitate to contact us in case you have other questions not answered below.

While some patients tolerate fibrous vegetables or stringy meat if chewed thoroughly, others might have to avoid them completely.

  • foods with added sugar, dried fruits
  • stringy meat
  • doughy bread
  • fibrous vegetables
  • carbonated beverages
  • alcohol
  • coffee
  • fried and fatty foods

Foods with high sugar content pass too quickly through the stomach into the intestines and cause dumping syndrome. Patients may experience stomach cramps, nausea, diarrhea, dizziness.

Due to alteration done to the digestive tract during gastric bypass alcohol has a bigger impact on the body than prior to surgery. Even small amounts of alcohol can produce inebriation.

Caffeine contained in coffee, may irritate the stomach, especially if consumed in large amounts. The stomach of gastric bypass patients is more sensitive to ulcers and caffeine irritation may lead to ulcers. Caffeine also interferes with calcium absorption. Ask the advice of your nutritionist on the calcium supplements to take. Other unpleasant effects of caffeine include jitteriness, hypertension, rapid heartbeat, dehydration. Dehydration may further cause headaches.

Dehydration is among the complication that can occur after gastric bypass surgery. To avoid it, make sure to drink sufficient clear water each day, but never drink together with your meals. Drink half an hour before eating, or at least an hour after eating.
