Many patients ask: which operation is right for me? There is no single answer for everyone, but there are key factors the surgeon considers.

Sleeve gastrectomy

The stomach is made smaller; it is one of the most common operations. In the triple-protected sleeve, omentopexy is added to reduce gastric twisting and heartburn.

Gastric bypass

Combines a smaller stomach with a re-routing of the intestine. It may be preferred in situations such as severe reflux or diabetes.

What decides the choice?

  • Body-mass index
  • Reflux or diabetes
  • Previous operations
  • Lifestyle and expectations
