Jonathan Aranow, MD is a specialized bariatric surgeon at the Middlesex Health Surgical Alliance and Center for Surgical Weight Loss.

Dr. Aranow received his training at Harvard Medical School’s Beth Israel Deaconess Medical Center.  Dr. Aranow is board-certified by the American Board of Surgery and a fellow of the American College of Surgeons (FACS). He is a member of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and a member of the American Society for Metabolic and Bariatric Surgery (ASMBS), where he has also served as President of the Connecticut chapter.

Dr. Aranow brought his skills to Connecticut in 1999. In 2001 he founded the Middlesex Hospital Center for Bariatric Surgery (now the Middlesex Health Center for Surgical Weight Loss), after recognizing the absence of bariatric surgeons in Connecticut at that time. Since then, he has performed more than 4,000 weight loss procedures with some of the best and safest results in the country. He offers patients a minimally-invasive, robotic-assisted gastric bypass surgery with the use of the da Vinci® surgical robot.

As an outspoken advocate for the morbidly obese individual, Dr. Aranow has achieved national recognition for his leadership role in securing insurance coverage for weight loss surgery patients as well as for the superb results he has seen in his surgical patients. He notes that following weight loss procedures his patients routinely experience dramatic improvements in health and self-esteem. Because of the known benefits of these procedures, Dr. Aranow has campaigned in the state and federal legislatures for expansion of insurance coverage for these life-saving surgeries. 

Dr. Aranow is adept at all available surgical techniques including SADI, duodenal switch, gastric bypass, sleeve gastrectomy, and minimally invasive procedures. His exceptional outcomes and comprehensive multidisciplinary program, which includes dietary and behavioral counseling, have received national recognition and have earned accreditation from the American College of Surgeons.

In addition to his bariatric practice at the Middlesex Health Center For Surgical Weight Loss, Dr. Aranow continues an active practice in gastroesophageal surgery to treat reflux disease (GERD) and hiatal hernias.
