Medical Director Melissa Bagloo, M.D., FACS
Board certified in general surgery and fellowship trained in minimally invasive and bariatric surgery, Melissa Bagloo, M.D., has been a member of the Valley Hospital medical staff since 2010. She also is a member of Valley Medical Group (VMG).
Dr. Bagloo specializes in all types of minimally invasive metabolic and weight-loss procedures, including sleeve gastrectomy, gastric bypass, adjustable gastric band placement, duodenal switch, and revisional bariatric surgery. She also practices general surgery, specializing in minimally invasive approaches to gallbladder surgery, hernia surgery, paraesophageal hernia repair and surgery for gastroesophageal reflux disease. She has a special interest in the surgical treatment of Type 2 diabetes mellitus and metabolic surgery.
"Our patients are the driving force behind our dedication in helping them to achieve successful weight loss and improve their quality of life," Dr. Bagloo says. "We assist patients in determining the best type of surgery for them, based on our personalized approach to caring for the whole person."
According to Dr. Bagloo, minimally invasive bariatric surgery significantly reduces incision size and recovery time. "We use a laparoscopic technique, inserting a fiber optic instrument through a small incision – barely the size of a thumbnail. This technique reduces blood loss, the chance of wound complications, and overall discomfort. The technique also reduces the amount of time patients stay in the hospital.”
Dr. Bagloo received her medical degree from the University of Florida College of Medicine in 2004. She completed her residency at New York University School of Medicine in 2009 and her fellowship at Weill Medical College of Cornell University and Columbia College of Physicians and Surgeons in 2010. She remained on the faculty for Columbia as an Associate Professor of Clinical Surgery until assuming her current role as the Medical Director for The Center for Metabolic and Weight-Loss Surgery at The Valley Hospital.
