How quickly will I lose weight after my Gastric Bypass?

The rate of weight loss after a gastric bypass varies from person to person based on many different factors. However, generally we estimate that you can expect to lose up to 60% of your excess weight in the first 2 years after having a gastric bypass. A lot of weight loss is often seen in the first 6 months after surgery but some people find that their weight plateaus after this. As with anyone trying to lose weight, it depends on how much you eat and what exercise you do.
