Marcus Reddy is Consultant Surgeon at St George's Hospital. He is the lead Upper GI Surgeon at St George's and developed the South Thames Bariatric Service which is preferred provider for NHS bariatric surgery in the region.

Mr Reddy trained in London and Australia where he trained in upper GI surgery, liver transplant, hepatobiliary surgery and laparoscopic surgery. His NHS and private practice spans a range of laparoscopic and open general surgery. He has a particular interest in laparoscopic gastric banding, sleeve gastrectomy, Roux en Y gastric bypass, laparoscopic cholecystectomy, laparoscopic and open hernia repairs. He performs anti-reflux surgery such as laparoscopic Nissen fundoplication, the LINX System and Stretta procedure as well as surgery for achalasia for local and regional patients.

Mr Reddy has published on management of biliary injuries following cholecystectomy, unusual hernias such as interparietal hernias and also follow-up of hernia repairs performed with pre-peritoneal techniques. He performs cholecystectomy and hernia repairs as day-case when appropriate and uses non-diathermy techniques such as Ultracision Harmonic Scalpel to avoid electrical conduction complications in laparoscopic surgery.
