Our Staff

Dr. Lloyd Stegemann is a board certified general surgeon who focuses his practice exclusively on medical and surgical weight loss. He has personally performed over 2,000 bariatric operations including gastric bypass, adjustable gastric banding, sleeve gastrectomy, and revisional surgery. Dr. Stegemann currently serves at the Medical Director of the Metabolic and Bariatric Surgery program at Bay Area Hospital and South Texas Surgical Hospital.

Dr. Stegemann received his medical degree from the University of Texas Health Science Center in Houston and then completed his surgical residency in San Antonio, Texas. During his surgical residency, he saw firsthand the devastating emotional and health effects of obesity on patients and their families. He also got to witness the enormous impact that bariatric surgery had on patients, not only dramatically improving their health but improving their quality of life. He decided early on in his training to devote his career to battling obesity and the devastating health consequences of this disease.

Dr. Stegemann was instrumental in organizing the practice of bariatric surgery in the state of Texas. He helped organize the first meeting of bariatric surgeons in the state which eventually led to the creation of the Texas Association for Bariatric Surgery (TABS) where he served as the group’s first President. Dr. Stegemann is also very involved with the American Society of Metabolic and Bariatric Surgeons and has been an active member on numerous committees. Dr. Stegemann currently serves on the Board of Directors of the Obesity Action Coalition (OAC), the only national non-profit organization that serves to educate the public on matters of weight, increase patient access to obesity treatments, and to end obesity discrimination. He remains active in trying to increase access to obesity treatments and fighting obesity discrimination.

Dr. Stegemann remains passionate about taking care of patients long after their operation. “Operating is certainly fun and I know we do it really well, but I think what really sets The Better Weigh Center apart from other practices is our commitment to education before and after surgery. Surgery allows us to get the body to reset to a healthier weight but to keep the weight off long-term patients need to commit to leading a healthier lifestyle and we believe strongly this needs to be taught and then reinforced over time. There’s still nothing that makes me happier than seeing a patient back 3, 4 or 5 years after their operation and they are mainting a healthy weight.”

When he isn’t working Dr. Stegemann enjoys traveling and spending time with friends and family.
