How much weight will I lose after bariatric surgery?

After weight loss surgery, most people lose almost one-third of their excess weight as early as 3 months after surgery.1 In general, the most weight is lost in the first 6 months and stabilises after 12-18 months.2 2 years after bariatric surgery, patients have reported to have achieved upto 59% excess weight loss i.e. more than half excess body weight.3

Weight loss management after surgery will depend on the type of procedure and your commitment to a healthier lifestyle. Effective weight loss solutions include exercising regularly and making smarter food choices. If you do not stick to it then you will not lose enough weight or may even put it back on again.2
