Institute of Minimal Access & Metabolic Surgery, Sir Ganga Ram Hospital is one of the pioneers in starting  the Bariatric Programme in the country. Today the center conducts a high volume of bariatric surgeries and we have follow up of over a decade. I have personally keen interest in Laparoscopic Sleeve Gastrectomy, which seems to be fast evolving as the ideal procedure for the Asian population.
