Diet after gastric sleeve. Longitudinal gastrectomy, or popularly known as stomach reduction surgery, is a laparoscopic operation. However, the steps after the operation are very important, and in this article, we will explain all the details related to gastric sleeve and what lifestyle should be adopted after the operation. It should be understood from the outset that losing weight and maintaining it is achieved with a lot of willpower, because although the stomach is smaller in size, its functions remain unchanged.

It should be specified at the outset that the physiological circuit of food is not changed, and you will not need to take nutritional supplements or vitamins for the rest of your life. There are some small restrictions, especially in the first part of the recovery period and immediately after the operation, says Dr Bogdan Amza. It is important for patients to be aware that this surgery also comes with a change in lifestyle and food intake.

Dietary recommendations after gastric sleeve surgery vary depending on your situation. On the first day after surgery you will be allowed to consume only liquids to allow time to adjust to the new condition.

Simple. To let the stomach heal itself, without demanding it with food.

Then depending on your progress, you can consume (in the first days):

  • Soup;
  • Unadulterated juice;
  • Tea.

Only after a week, you can start integrating mashed foods into the menu. They should have a paste-like consistency, without solid pieces. Eat little and often up to 6-7 meals a day. Each meal will consist of 4-6 tablespoons of food. It is recommended to eat slowly, without rushing at each meal. Take small bites with a break in between.

For hydration, drink 2-3 tablespoons of water or unsweetened tea every 10-15 minutes.

If a feeling of weakness occurs, a vitamin drink (flat) may be taken, but only on the doctor’s advice, and should not exceed 500 ml per day. But this only from the second or third day after the operation.
