Diet Recommendations for After Weight-Loss Surgery

A gastric bypass diet helps people who are recovering from sleeve gastrectomy and from gastric bypass surgery — also known as Roux-en-Y gastric bypass — to heal and to change their eating habits. Your doctor or a registered dietitian can talk with you about the diet you’ll need to follow after surgery, explaining what types of food and how much you can eat at each meal. Closely following your gastric bypass diet can help you lose weight safely and keep you feeling well too.

The gastric bypass diet is designed to:

  • Allow your stomach to heal without being stretched by the food you eat
  • Accustom you to eating the smaller amounts of food that your smaller stomach can comfortably and safely digest
  • Help you lose weight and avoid gaining weight
  • Avoid side effects and complications from the surgery

Diet recommendations after gastric bypass surgery vary depending on your individual situation. A gastric bypass diet typically follows a staged approach to help you ease back into eating solid foods. How quickly you move from one step to the next depends on how fast your body heals and adjusts to the change in eating patterns. At each stage of the gastric bypass diet, you must be careful to:

  • Avoid dehydration.
  • Wait about 30 minutes after a meal to drink anything and avoid drinking 30 minutes before a meal.
  • Eat and drink slowly, to avoid dumping syndrome — which occurs when foods and liquids enter your small intestine rapidly and in larger amounts than normal, causing nausea, vomiting, dizziness, sweating and diarrhea.
  • Eat lean, protein-rich foods daily.
  • Choose foods and drinks that are low in fats and sugar.
  • Avoid alcohol.
  • Limit caffeine, which can cause dehydration.
  • Take vitamin and mineral supplements daily as directed by your health provider.
  • Chew foods thoroughly to a pureed consistency before swallowing, once you progress beyond liquids only.

The gastric bypass diet can help you recover from surgery and transition to a way of eating that is healthy and supports your weight-loss goals. Remember that if you return to unhealthy eating habits after weight-loss surgery, you may not lose all your excess weight, or you may regain any weight that you do lose.
