Conversion of Sleeve to MGB
in Frankfurt / Main
Optimization of weight loss through follow-up surgeries
Converting a sleeve gastrectomy into a Mini Gastric Bypass (MGB) is a proven option for patients who have not achieved sufficient weight loss despite previous Sleeve Gastrectomy Surgery or who suffer from complications such as reflux. By readjusting the digestive tract, calorie intake is further reduced, and the metabolism is positively influenced.
This procedure combines the advantages of the Mini Gastric Bypass: a reduced stomach capacity and bypassing part of the small intestine. This not only leads to increased weight loss but can also improve concomitant diseases such as diabetes or high blood pressure. Our experienced and empathetic team would like to be at your side.
