What is the Gastric sleeve in the Iran diet?

Following a pre-set diet is essential to achieving surgical goals. It can also prevent the complications of weight loss surgery including diarrhea, nausea, vomiting, constipation, and leakage.

The sleeve surgery diet, which has many benefits and leads to maximum weight loss, should have the following characteristics:

  • you should start it 3 weeks before gastric sleeve
  • After your surgery, you should convert your diet into liquids gradually. (This gradual process may take up to 4 weeks, depending on the doctor's opinion)
  • The diet should include healthy foods with limited snacks.
  • Be sure to eat 60 grams of protein a day.
  • Drink at least 2 liters of low-calorie fluids a day.
  • The diet should include vitamins and supplements.

Important points about gastric sleeve diet 

The first important point is that you should challenge your new stomach by eating solid or overeating foods under no circumstances. Keep in mind that your stomach can only hold 3 to 4 ounces of food, which means that the patient will probably feel full after eating 2 to 3 tablespoons.

About 6 to 9 months after gastric sleeve, the stomach stretches and opens more space. This will allow you to have a normal and new diet.

If you accidentally eat a lot of food after your weight loss surgery, you will most likely gain weight and your stomach will stretch a little. This may happen at first and there is no need to worry.

It may seem difficult, but in the first week, you are only limited to dilute fluids. However, this period is not very difficult because most patients have no appetite at all this week. In gastric sleeve surgery, the cause of the patient's anorexia is the lack of hunger hormone or ghrelin after surgery. because the surgeon will remove the part of the stomach that is responsible for producing this hormone.
