Why Are Dietary Changes So Important After Bariatric Surgery?

One of the most effective weight loss options, gastric sleeve or bypass surgery reduces the amount of food you may consume at one time. The gastric sleeve post-op diet is designed to:

● Prevent complications or side effects of surgery
● Allow your stomach to heal completely without being stretched
● Prevent discomfort, gas, nausea, and vomiting
● Provide small amounts of food that your stomach can comfortably digest
● Help you lose weight in a fast but safe manner
● Build new eating habits to support your weight loss goals

What Foods Should You Eat Immediately After Surgery?

Beginning immediately, and as part of your ongoing weight loss surgery diet plan, avoid drinking anything 30 minutes prior to, and for 30 minutes following a meal. This allows your stomach to be fully emptied and able to digest a small meal.

For the first two weeks or so following your surgery, stick to  liquid only foods:

● Clear broth
● Skim milk, soy milk.
● Sugar-free Jell-O or popsicles
● Protein shakes.
● low fat, low sugar pudding.
● Water, or water flavored with crystal lite.

Typically, your gastric sleeve or bypass surgery meal plan will require 3-6 small meals each day. These meals consist of 4-6 tablespoons of food, which should be eaten slowly over a period of about 30 minutes. Eating slowly prevents discomfort, nausea, and  “dumping syndrome,” where food passes into the small intestine too quickly.

What’s Up Next on the Menu?

When you are tolerating liquids well, usually after 14 days or so, you can add strained or mashed foods to your diet. They should be pureed to the consistency of a thick liquid or smooth paste, without any lumps.

Some gastric sleeve diet recipes ingredients include:

● pureed Cooked vegetables
● pureed tuna salad, chicken salad, or Egg salad.
● Creamed soups, blended smooth
● Cottage cheese
● Scrambled eggs

To achieve the right consistency, add a little bit of:

● Water
● Skim milk
● Broth
