Our Weight Loss Services

If you’ve struggled with obesity, you know it’s more than just a weight problem. It’s a lifestyle problem. It’s a self-esteem problem. Above all, it’s a major health problem. In fact, clinically severe obesity — at least 100 pounds over ideal body weight — is classified as a serious disease.

Weight reduction surgery improves your quality of life and lessens or eliminates associated diseases like diabetes, hypertension, obstructive sleep apnea and high cholesterol. It also positively impacts other areas, like gastroesophageal reflux disease, stress incontinence, cardiac function, infertility and osteoarthritis. Weight loss surgery might even help you reduce the need for certain medications. Most importantly, it can put you back in control of your life.

University Bariatric Center provides a comprehensive approach to the bariatric surgery process. Learn about our weight-loss services, including bariatric surgery and metabolic weight loss programs.
