What is a gastric tube operation?
During this operation, a certain part of the stomach is surgically removed, a tubular stomach remains, which is why this method is also known as gastric sleeve surgery. Since you can only eat a limited amount of food at once after the operation, patients feel full more quickly and this feeling of fullness then leads to a loss of appetite over time.
Another advantage that should not be neglected is the support of weight loss by removing the stomach tissue (fundus), in which the hormone "ghrelin", which is responsible for the feeling of hunger, is formed. Ghrelin has an appetite stimulating effect by stimulating receptors in the brain's appetite zone.
During the gastric sleeve surgery, the fundus area of the stomach in which the ghrelin hormone is formed is removed, which automatically leads to a loss of appetite. It's a very simple method and the complication rates are very low. Weight loss of 60-70% is expected within a few years of surgery. Another surgical method, the so-called "sleeve gastrectomy", is only suitable for patients with a very high BMI value; this is only performed to avoid undesirable complications in gastric bypass operations. Since this operation only restricts the amount of food, these people do not need to take any additional vitamins or minerals.
Who is the gastric tube operation suitable for?
The gastric sleeve surgery method is used in patients between 18 and 65 years of age who have tried frequently to lose weight with diet and exercise and were unsuccessful, with a corresponding body mass index of 40 kg / m2.
Sleeve gastric surgery can also be used for patients with a BMI between 35 and 40 kg / m2 with additional diseases such as diabetes, high blood pressure and sleep apnea.
It is also possible to use this method on patients with a BMI below 35 kg / m2 who suffer from severe secondary diseases.
What are the advantages of gastric sleeve surgery?
Patients with healthy living habits experience weight loss quickly and effectively and can easily maintain their shape.
As weight loss increases, there is a serious improvement in secondary health problems.
After gastric sleeve surgery, patients who consume small amounts of food have a significantly faster feeling of satiety.
As the area of the stomach where ghrelin is formed is removed from the body, the patient's appetite decreases sharply after the operation.
Pyloric valves, which control the passage of nutrients into the intestine, are retained during gastric sleeve surgery.
