Question: 1 / 650

What percentage of weight loss can typically be expected after laparoscopic gastric banding?

30-40%

40-55%

Following laparoscopic gastric banding, patients can typically expect a weight loss of 40-55% of their excess body weight. This range is supported by clinical studies and long-term data that show the effectiveness of the procedure in helping individuals achieve significant weight loss over time. The gastric band works by creating a smaller stomach pouch, which restricts food intake and enhances satiety, ultimately contributing to sustainable weight loss.

While some patients may experience more significant weight loss, the 40-55% range reflects an average outcome that incorporates variability due to factors such as adherence to dietary recommendations, levels of physical activity, and individual metabolic differences. Other surgical options or interventions, such as gastric bypass or sleeve gastrectomy, may lead to higher percentages of weight loss, but gastric banding is designed to provide a more gradual and less invasive option for patients seeking surgical assistance with obesity.
