Weight-Loss Surgery Program

Weight-loss Success

Clinical studies show that following weight-loss surgery, most patients lose weight rapidly and continue to do so until 18 to 24 months after the procedure. Patients may lose 30 to 50 percent of their excess weight in the first six months and 77 percent of excess weight as early as 12 months after surgery.

Another study showed that patients can maintain a 50 to 60 percent loss of excess weight 10 to 14 years after weight-loss surgery. Patients with higher initial body mass index (BMI) numbers tend to lose more total weight. Patients with lower initial BMIs will lose a greater percentage of their excess weight and will more likely come closer to their ideal body weight. Patients with type 2 diabetes tend to show less overall excess weight loss than patients without type 2 diabetes.

The surgery has been found to be effective in improving and controlling many obesity-related health conditions. A 2000 study of 500 patients showed that 96 percent of certain associated health conditions studied (such as back pain, sleep apnea, high blood pressure, diabetes and depression) were improved or resolved. For example, many patients with type 2 diabetes, while showing less overall excess weight loss, have demonstrated excellent resolution of their diabetic condition—to the point of having little or no need to continue medication.
