How much weight is lost in an obesity operation?

How to measure it:

Estimate your excess weight (simply by comparing yourself to the people around you at the same height).

Calculate the ratio (if you have 50kg left over, you would lose 25-30 kg with the BG, 30-35 with the TG, 35-40 with the Bypass).

Type of operation and percentages of lost weight

Adjustable Gastric Banding: 45-50%.

Gastric tube / Sleeve: 60-70%.

Gastric Bypass: 65-75%.

Success in weight loss depends on the patient making a real change in their dietary habits, even in operations with malabsorption (Gastric Bypass), the patient can regain the lost weight if it is proposed.
