Gastric Bypass Diet

Diet after Gastric Bypass Surgery

Proper nutrition is essential to healing after gastric bypass surgery. You will be restricted to an all-liquid diet immediately following the procedure, and you will need to sip fluids slowly and avoid growing too full – this will allow your newly-formed pouch sufficient time to heal. After the pouch has healed, you will still need to limit portions to sizes that your stomach pouch can handle in order to maintain weight loss. Patients of gastric bypass surgery typically follow these diet phases after surgery:

  1. Clear Liquids Only: Immediately following surgery, your diet will be restricted only to sipping clear liquids. This may include diluted apple juice, artificially sweetened non-carbonated drinks, sugar-free gelatin, and beef or chicken broth.

  2. Full Liquids: Within one week of surgery, you will begin to add full liquids to your diet. These may include yogurt or sugar-free pudding, milk and protein shakes, and low-fat creamed soups.

  3. Blended or Pureed Foods: By the third week, you will begin to puree your foods. You will still need to keep your meals small and focus on high-protein foods.

  4. Textured, Non-Pureed Foods: By the fifth or sixth week after surgery, you will begin eating soft, non-pureed foods. Be sure to chew your food thoroughly and refrain from eating fibrous vegetables, breads, and meat that is too tough. Your diet should consist of vegetables, fruits, low-fat proteins, heart-healthy fats, and healthy carbohydrates.

After bariatric surgery, it is essential that you supplement your diet with protein, vitamins and minerals. Because each patient has different needs, the Temple dietitian will determine which supplements you should take and provide you with a list of product options to choose from. You will need to have your blood checked several times during the first year after surgery, and once each year after that, to ensure that your body is absorbing nutrients properly.
