The sleeve gastrectomy is the most commonly performed bariatric operation worldwide - for good reason.

A proven procedure that reduces the stomach. At the same time, the hunger hormone ghrelin is reduced and the release of the satiety hormone GLP-1 is increased. Less hunger, faster satiety - lasting success.

The Procedure

Sleeve Gastrectomy

During the sleeve gastrectomy, the stomach is reduced along the greater curvature to approximately 15% of its original size and shaped into a tube. By removing the gastric fundus, the hunger hormone ghrelin is significantly reduced, leading to a markedly decreased feeling of hunger.

Why This Procedure

Benefits of the Sleeve Gastrectomy

01
Most commonly performed bariatric operation worldwide
The sleeve gastrectomy is the most frequently performed bariatric operation worldwide - proven, safe, and with excellent results.
02
Shorter procedure time compared to bypass
The procedure takes only 30-45 minutes and is performed entirely laparoscopically. Short hospital stay and fast recovery.
03
Natural digestion preserved
No intestinal rerouting, no anastomoses, no malabsorption - and still lasting results.
04
Can serve as a first step before a bypass
The sleeve gastrectomy can be extended to a gastric bypass or SADI-S later if needed.
05
Significant reduction of the hunger hormone ghrelin
By removing the gastric fundus, the hunger hormone ghrelin is significantly reduced - less hunger, faster satiety.
06
Increase of the satiety hormone GLP-1
The altered stomach anatomy promotes the release of the satiety hormone GLP-1 - for a more sustained feeling of fullness.

Frequently Asked Questions

Well Informed for Your Consultation

How does the sleeve gastrectomy work?

The stomach is reduced along the greater curvature to approximately 15% of its original size and shaped into a tube. By removing the gastric fundus, the hunger hormone ghrelin is significantly reduced and the satiety hormone GLP-1 is increased.

How much weight can you lose?

Patients lose an average of 50-65% of their excess weight within the first two years. The sleeve gastrectomy is particularly well suited as a standalone procedure for a BMI between 35 and 50.

Is the procedure reversible?

The sleeve gastrectomy is not reversible, as part of the stomach is removed. However, the procedure can be extended to a gastric bypass or SADI-S if needed, should the result be insufficient.
