How Much Will You Weigh After Surgery Calculator

Regardless of which weight loss surgery you choose, you can expect to lose a certain amount of weight from bariatric surgery. This calculator will tell you how much weight you can expect to lose from each bariatric procedure and what you can expect to weigh two years after surgery.

The calculations are based on average weight loss per procedure. To lose the average amount of weight, you’ll need to follow your surgeon’s pre-operative and post-operative guidelines.

Long term diet and exercise changes along with other habit changes can lead to weight loss that exceeds the averages used in these calculations.
