FORMER IFSO WORLD PRESIDENT · MEDUNI VIENNA · AKH VIENNA
Univ.-Prof. Dr.
Gerhard Prager
Professor for Bariatric & Endocrine Surgery
For over 25 years, I have been guiding people on their journey to a healthier life – with time, empathy, and the most advanced methods in the world.
Obesity is a chronic disease – not a matter of willpower.
The first step toward change begins with understanding that you deserve support. Medically sound. Without judgment.
With a BMI of 40 or above – or 35 with comorbidities – health insurance typically covers the cost of a bariatric procedure.
The details will be clarified during the initial consultation.

THE PROFESSOR
International expertise – applied directly to your care
As the former World President of IFSO, the international society for bariatric and metabolic surgery, I helped shape the global standards that define the gold standard today. In this role, I succeeded a professor from Harvard Medical School.
“80% of type 2 diabetics no longer need medication after a bariatric procedure.”
Every patient receives my full attention. From the initial consultation through the surgery to long-term follow-up care – I am personally there for you.
