Dietary Habits to Adopt Post Gastric Bypass Surgery

A gastric bypass refers to a surgical procedure that aims at helping an individual lose weight by transforming the manner in which their small intestine and stomach process the food they consume. What the surgical procedure does is that it reduces the size of the stomach and re-routes the intestine. This results in giving a person the sensation of feeling full with less food as well as a reduction in the amount of food that is digested and absorbed. 

Following bariatric surgery, a gradual progression of diet is important with a focus on ensuring a lifelong change in eating habits with a focus on ensuring adequate proteins are taken daily. With the changes in intestinal rerouting, there is a need to ensure adequate vitamin and minerals supplementation. Without supplementation, there may be a deficiency in the months following the operation and follow up is imperative to ensure that any deficiencies are promptly corrected. 

Following surgery, there is a gradual progression of diet. This starts from the first day after surgery. 

A day post gastric bypass surgery, clear fluids and liquids are started including water, sugar-free popsicles and jello and once tolerated clear liquids, one can then progress on to other fluids and liquids such as protein shakes. 

Following a week-long liquid diet, one can advance to the consumption of mashed and pureed food. The recommended food consistency is smooth and thick, without any lumps or solid pieces. For example, thin cream of wheat, thin oatmeal, pureed cottage cheese, etc., all mixed, diluted, and pureed with water or low-fat milk. A gradual shift to soft foods is continued and this includes fish, eggs and chicken, and ground lean meat. Simple carbohydrates must be avoided. 

People recovering from gastric bypass surgery must be sure to avoid dehydration and drink adequate amounts of water in order to remain hydrated. Also, it is recommended to avoid drinking fluids half an hour before and after a meal. It is also important to chew food slowly. Patients are encouraged to drink at least 64oz of fluid daily. 


Foods to Avoid

Certain kinds of drinks and foods must be avoided following a gastric bypass as these may reduce successful weight loss. These drinks and foods include:

  • Carbonated and sugar-sweetened liquids, such as soda

  • Dry and hard foods, which might be difficult to swallow following the surgery

  • Foods with a high glycemic index, such as rice, potatoes, and bread, which can cause a rapid advance in the blood sugar levels

  • Calorie dense foods and beverages, such as cakes, ice-cream, milkshakes, and chocolate

  • Alcohol for 12 months after surgery
