Gastric Sleeve Post-Operative Diet

After gastric sleeve surgery is performed, a patient’s stomach can only consume 3 to 4 ounces of food, down from the average of 60 ounces a stomach typically can hold. In order to have a successful overall experience, the patient must follow a strict diet plan immediately after surgery.

In conjunction with the proper diet, a patient should take several vitamins – a multivitamin with iron, Calcium (1,500 to 2,000 mg), Vitamin D and maybe even B complex. Always consult a doctor before taking a new supplement.

Clear Liquid Diet

During the first week after surgery, a patient should aim to consume 64 ounces of fluids daily. Avoid sugary drinks, caffeine or carbonated beverages. A patient should never use a straw and take small sips. Approved drinks include: water, chicken or beef broth, skim milk, sugar-free Jell-O or Popsicles, sugar free Crystal light, green tea, low-sugar fruit juices (no orange), fruit ices and ice chips.

Full Liquid Diet

After about a week of clear liquids, a patient will transition to all liquids for two more weeks. The patient must focus on consuming as much protein as possible. The required 64 ounces daily still comes into play, but 60-70 grams of proteins should also be consumed. For those who are lactose intolerant, they may have rice or soy milk. Some approved liquids include: skin milk, soy milk, no pulp fruit juice, sugar free gelatin, soups, fruit smoothies (fully blended), Carnation, sugar-free popsicles, V-8, applesauce and protein shakes.

Soft Foods Diet

After liquids, the body will transition to soft foods for a week. Patients should continue to consume 60 to 70 grams of protein while staying away from sugar, fat and carbohydrates. Some approved soft foods include: scrambled eggs, tuna fish with low-fat mayo, low-fat cottage cheese, mashed fruit, low-fat cheese, mashed vegetables, bananas, mashed potatoes and yogurt.

Because the patient is still acclimating to their new stomach size, several small meals should be consumed daily. Consume only 3 to 4 ounces at a time. A patient should aim to consume 600 to 800 calories a day.

Solid Foods Diet

After these four weeks of liquids and soft foods, the body should now be ready for solid foods. This transition will include all the foods you will now be eating for your lifetime. Some food to always avoid to keep the weight off include (and are not limited to): bacon, sausage, peanut butter, processed meats, fried foods, rice, pasta, desserts, salty snacks, alcohol, sauces and fruit juice.

Ultimately, following these diets strictly will only ensure that patients will lose the most amount of weight in the safest way possible.
