If you are thinking about bariatric and metabolic surgery (surgical treatment for obesity and associated comorbidities such as type 2 diabetes) and are having doubts about whether it is right for you, you're not alone. Wondering if bariatric surgery is right for you is a very common concern.
Bariatric and metabolic surgery is a life-changing procedure, and making that decision requires research, a good amount of reflection and discussion with your doctor. If traditional weight loss methods have not worked, bariatric and metabolic surgery may be the right answer for you.

An essential part of your preparation is the opportunity to hear from one of our surgeons and have your questions answered. Our goal is to make your journey as successful as possible.
