How much weight can I expect to lose after bariatric surgery?
A. Most gastric bypass patients experience fairly rapid weight loss in the first three to six months after surgery. Weight loss slows, but generally continues up to 12 to 18 months after surgery, averaging 65 to 75 percent of excess body weight. After 18 months, it is critical to adhere to the low-fat, low-sugar diet and exercise recommendations you will receive in order to maintain your weight loss. With the LAP-BAND® weight loss is generally slower and more gradual compared to the gastric bypass. Weight loss may continue for up to two years.
