How Much Weight Will I Lose After a Gastric Bypass?

Weight loss amount with gastric bypass
Most patients after gastric bypass surgery will lose 70 - 80% of their excess weight in in the first 12 months. Unfortunately some patients will regain 10 - 20% of the excess weight over the following 3 - 5 years resulting in long term 60% excess weight loss. Close follow-up and having a surgeon with a comprehensive multidisciplinary team can give you better results.
Expected weight loss after gastric bypass surgery
The average excess weight loss for gastric bypass surgery at one year is approximately 75 to 85%. So if your excess weight is 300 pounds you will probably lose 225-255lbs in the first year. However, if you exercise and eat properly more weight loss can be achieved. At five years, the average excess weight loss is approximately 65%.
