What is Bariatric Surgery?
Bariatric surgery refers to a group of surgical procedures that help people with obesity achieve significant, lasting weight loss when diet, exercise, and medication have not been sufficient. These operations work by changing the anatomy of the digestive system — reducing the size of the stomach, altering how the intestines absorb nutrients, or both — leading to reduced hunger, earlier satiety, and meaningful metabolic improvements.
More than weight loss
Bariatric surgery is one of the most effective treatments available for obesity and its related conditions. Beyond weight loss, these procedures have been shown to significantly improve or resolve type 2 diabetes, high blood pressure, sleep apnea, high cholesterol, and joint pain. For many patients, the metabolic benefits begin within days of surgery — often before significant weight loss has even occurred.
Who is a candidate?
Bariatric surgery is generally considered for adults with a BMI of 40 or higher, or a BMI of 35 or higher with at least one obesity-related health condition such as diabetes or hypertension. Adolescents with severe obesity may also be candidates. Eligibility is determined through a thorough evaluation that includes medical history, nutritional assessment, psychological readiness, and a discussion of goals and expectations.
The robotic advantage
Dr. Dimou performs all bariatric procedures using the da Vinci robotic surgical system. Compared to traditional open or laparoscopic surgery, the robotic platform offers enhanced three-dimensional visualization, greater precision in tight anatomical spaces, reduced blood loss, and faster recovery times. It is particularly advantageous for complex and revisional cases where precision is critical.
A partnership, not just a procedure
Surgery is a powerful tool, but lasting success depends on the relationship between patient and provider. Dr. Dimou's approach emphasizes education, shared decision-making, and long-term support — helping patients understand not just what will happen during surgery, but how to build a sustainable, healthy life afterward.
