Bariatric or metabolic surgery actually refers to the same type of surgery. While the term bariatric surgery is more targeted at surgery performed with the intention for patient to lose weight, metabolic surgery is more targeted at surgery to be performed to improve the metabolic parameters of the patient including reducing cardiac risk parameters, improving diabetes and possibly resolving it in some cases, improvement in hypertension profile.

He will also discuss the different options available according to your individual Body Mass Index and related co-morbidities, and then make the relevant recommendations.
