The sleeve gastrectomy is a surgical procedure that can be used for obese patients. The stomach volume is reduced in size. As a result, the feeling of fullness occurs earlier when food is consumed. As a result, the patient eats less food, which tends to result in a lower calorie intake. Due to the resulting calorie deficit, the patient will slowly but steadily lose weight and thus achieve a healthier body.

The reduction in stomach volume is achieved by removing a large part of the stomach. Usually the stomach volume is reduced by 90 percent.

After the operation, the patient has to stay in hospital for about a week.

There are alternatives to the tubular stomach, such as gastric bypass.

What are the advantages of a sleeve gastrectomy?

By reducing the size of the stomach, the absorption of food is reduced. This results in a slow but steady weight loss for pathologically overweight patients.

The main advantage of the sleeve gastrectomy method is that the stomach is not affected in its function. This has many advantages that can lead to problems with other methods, such as gastric bypass.

Vitamin B12 is mainly absorbed via the stomach. If the absorption is disturbed, it can result in permanent damage to the nervous system in the long term. This is not a problem with the sleeve gastrectomy.

Sleeve gastrectomy and gastric bypass have similar positive effects on weight loss according to various studies, but the tubular stomach seems to be the more tolerable option.

What are the disadvantages of a sleeve gastrectomy?

Here I would not like to conceal the disadvantages of sleeve gastrectomy! Basically, however, you should weigh all the disadvantages against the health problems you may or may not be able to cure if you are still obese. Diabetes, high blood pressure, joint problems, etc., which are the consequences of being overweight, also mean a not inconsiderable risk if not treated.

In principle, every medical intervention carries a risk. Even the most harmless medical interventions could cause people to die, either because of a chain of unfortunate coincidences or because the doctor makes a mistake. That is why such an operation should always be the very last option to get rid of overweight.

Do some sports, find companions for losing weight, change your diet. Only if all of this has not worked out for you you should consider an operation.

The gizzard operation is irreversible. It is not possible to return to the original state of the stomach after weight loss.

In the short term, a nutrient deficiency may occur. Patients should keep this in mind and have their doctor check for deficiencies regularly.

Regular overeating can cause the remaining stomach to expand again with renewed weight gain.
