Obesity is generally interrelated to massive limitations in life quality or social life. The risk of subsequent diseases such as diabetes, cardiovascular disease or high blood pressure is elevated. Surgical steps for obesity, such as sleeve gastrectomy, may be effective solution.

This minimally invasive surgery reduces the stomach in the actual sense. A major part of the stomach is removed, whereby a sleeve-like stomach remains.

Due to the reduced volume of the stomach, satiation occurs much earlier. The general functionality of the stomach and intestine is unimpaired by the sleeve gastrectomy. Everything may be eaten, just like before; only less.

The surgery is done in general anesthesia.

Questions and answers on sleeve gastrectomy

What is Sleeve Gastrectomy

The term sleeve gastrectomy arises from the final shape of the stomach after surgery. A major part of the original stomach is removed, whereby the remaining stomach gets that shape.

Is the surgery reversible?

No. Due to the fact that a major part of the stomach is removed in surgery, this operation cannot be reversed.

What are the risks?

As any surgery, this may entail complications. Much is dependent on the patient’s individual health status. Since surgery is done with general anesthesia, it must be clarified whether there are earlier diseases or allergies to certain drugs. In rare cases blood vessels or surrounding organs can be injured.

How long will the surgery take?

The surgery takes approx. 60 minutes.

When is sleeve gastrectomy offered?

If several conservative methods have been unsuccessful then a sleeve gastrectomy may be offered in case of obesity due to high volume eating.

Do I have to keep diet afterwards?
Food which is rich in nutrients and variable is generally recommended. In particular the amount of food taken requires discipline. If too much food is consumed, the stomach may be enlarged again.
Which weight loss can be expected?
Generally, this surgery achieves a weight reduction of 50% of the actual excess weight.
When can I take up sports again?
You may resume your sport activity after approx. 4 weeks.
