Types of Weight-Loss Surgery

No matter what technique, the stomachs of patients who have undergone weight loss surgery have become so small in volume that they feel full with very little food. They even need to chew food for a long time before swallowing in order not to vomit. Those who have undergone weight loss surgery are advised to start their meals with protein.

Because if you eat the vegetable first, there is no room for protein in your stomach. In addition to limiting yourself to only three small meals a day, it becomes impossible to digest red meat, the peel of some fruits, and many vegetables. In other words, with so little food, you may already be without food, and you may need to remove many valuable foods necessary for your health from your life. As you can see, this is not at all a healthy way of eating! Hair loss is observed in almost all patients who have undergone weight loss surgery –which is the best evidence that the body is not getting enough nutrients and gives danger signals.

 You can see different types of weight loss surgery because they are divided into subheadings, but mainly two types of weight-loss surgeries performed. There are gastric bypass and gastric sleeve surgeries. Successful results can be obtained in the treatment of obesity thanks to gastric bypass surgery and gastrectomy called a gastric sleeve. Two different stomach reduction surgeries are preferred according to different comorbidities.

Thanks to the method of taking about 80-85% of the stomach, the volume of the stomach can be significantly reduced. After this operation, the person eats less and feels full in a short time. Therefore, it is possible to lose weight quickly and healthily. In both types of surgery, they begin to eat less, and most of the food they eat does not reach the duodenum and is therefore excreted without absorption. Therefore, even if you eat high-calorie foods, you will lose fat and weight.

Another method of stomach reduction, the gastric balloon, is more of an endoscopic method than a surgical method. With this method, a gastric balloon remains in the stomach for 6 months, and as the volume of the stomach decreases, the person begins to lose weight.


  • Gastric sleeve: It is the most common method of obesity surgery. 80% of the stomach is removed by the laparoscopic (closed) method. Since the hunger hormones are in the removed area, the feeling of hunger decreases. A person feels full. Significantly lose weight. It is more preferred because of the low number of complications after surgery.
  • Gastric bypass: The purpose of the procedure is to reduce the stomach and shorten absorption. Gastric bypass is one of the most performed procedures and is performed by the laparoscopic (closed) method. In surgery, a small stomach tube with a volume of 30ml is first created at the entrance to the stomach. The remaining large part of the stomach is separated from the tube. The small gastric tube connects with the small intestine. Thus, nutrients pass through the small gastric tube into the small intestine. At the end of the procedure, the feeling of hunger decreases, while the blood sugar level remains normal. With the operation of gastric bypass, a 60-80% reduction in excess weight is observed.
  • Gastric balloon: It is a silicone balloon that, after being inserted into the stomach, is inflated with air or liquid to a volume of 400-700 cc. Diet and exercise is a temporary weight loss method that is applied endoscopically in those who cannot lose weight easily, those who do not want to have surgery, and patients who are at high risk of surgery
