Guy was appointed as an NHS consultant surgeon in 2004 at St. Richard’s Hospital, Chichester and has specialised in bariatric surgery for 18 years. In that time he has performed more than 2000 weight loss procedures, including over 1000 laparoscopic Roux en-Y gastric bypasses, 500 laparoscopic adjustable gastric bands and 250 laparoscopic sleeve gastrectomies. Much of his time is now spent concentrating on revision bariatric surgery including gastric band to bypass and sleeve to bypass.
With Shaw Somers he set up the NHS bariatric surgery service at St Richard’s Hospital and formed Streamline Surgical in 2006. He now works part time for the NHS, only performing bariatric surgery, to allow him to assist in the management of Streamline Surgical. Guy practices privately in Central London, Harrow, Guildford and Chichester.
