Long term

Although restrictive operations lead to weight loss in almost all patients, they are less successful than malabsorptive operations in achieving substantial, long-term weight loss. About 30 percent of those who undergo VBG achieve normal weight, and about 80 percent achieve some degree of weight loss. Most studies have suggested that 10 years after surgery, only 10% of patients maintain a minimum weight loss of at least 50% of their total excess weight at the time of their initial surgery.

Some patients regain weight. Others are unable to adjust their eating habits and fail to lose the desired weight. Successful results depend on the patient’s willingness to adopt a long-term plan of healthy eating and regular physical activity.
