While bariatric weight loss surgery isn't a one-size-fits-all solution, and eligibility can vary from person to person, there are general criteria that indicate whether someone might be a suitable candidate for this procedure and stand to benefit from it:
If their BMI (body mass index) is 30 or over
If they have tried several other means to lose weight (diets, exercise) but have had no long-term success
If they suffer from any weight-related diseases, such as Type II diabetes, arthritis, heart conditions, fatty liver etc.
If they are a teenager and have a BMI of 30 or over.
If any of this runs true for you or any of your loved ones, then we firmly suggest contacting your GP or the professional staff of a weight loss surgery clinic first, before deciding. Every surgical procedure comes with a number of health risks and a good doctor will help you value these risks and suggest the best path to take.
