Are You A Candidate?

Is bariatric surgery right for you?

Bariatric surgery has been deemed a safe and effective method for achieving long-lasting weight loss, but it’s not right for everyone. The decision to have bariatric surgery should be made only after understanding the results and consequences of this life-changing surgery.

Those who should consider weight loss surgery typically have 30 to 50 kg of excess weight. Good candidates have also tried other methods of weight loss, including diets and exercise, without achieving long-term success.
