Onvida Health is proud to share the expansion of its comprehensive weight-loss care program with the introduction of the duodenal switch procedure. This innovative surgery combines two of the most effective weight-loss approaches into a single, powerful treatment designed to help patients dealing with severe obesity achieve lasting results and improved health.
The duodenal switch is a weight-loss surgery that combines stomach reduction with intestinal rerouting. The operation is especially impactful for patients who have struggled with severe obesity or Type 2 diabetes, providing both transformative weight loss and significant health benefits.
“The duodenal switch is one of the most powerful and transformative tools we have for patients that are living with severe obesity,” said Dr. Robert King, Bariatric Surgeon at Onvida Health. “For many patients, this surgery is truly life changing. It allows them not just to lose weight but feel better, move more easily, and take back control of their health. And now, they can do that right here in Yuma.”
Led by bariatric surgeons Dr. Robert King and Dr. Gustavo Ortega, this milestone expands Onvida Health’s already comprehensive program, giving patients even more options and support on their journey to better health. Performing the operation requires a high level of special knowledge and teamwork, as it is a complex operation that requires advanced surgical skill and careful coordination.
Onvida Health’s weight-loss program has been further strengthened by the addition of Dr. Ortega, a highly trained bariatric surgeon whose fellowship focused on duodenal switch and other advanced procedures. Together, Dr. King and Dr. Ortega are strengthening Onvida Health’s Committed to Progress pillar by ensuring residents across southwestern Arizona have greater access to world-class bariatric care close to home.
“The addition of the duodenal switch reinforces the team’s commitment to providing comprehensive, individualized weight-loss care to Yuma and the surrounding communities,” said Dr. Gustavo Ortega, Bariatric Surgeon at Onvida Health. “It’s another example of our commitment to progress and to caring for the communities we have the privilege of serving.”
