Bariatric Procedures Opting for weight-loss surgery is not an easy choice. New treatments and safer techniques are making surgical intervention an option for more people. While the goal of any bariatric procedure is ultimately to improve health through medically supervised weight loss, results will vary depending on the procedure and the individual. Greenwich Hospital offers three types of weight-loss surgery. Each uses a whole-person approach that includes a team of medical professionals to assess the physical, emotional and psychological health of the patient prior to surgery. All procedures are done by Greenwich Hospital’s internationally recognized bariatric surgeons who use minimally invasive techniques, resulting in less scarring and quicker recovery. Choosing the most appropriate type of surgery is determined on an individual basis depending on a patient’s health and circumstances.
