Weight Management & Bariatric Surgery

Live your best life.



Considering weight loss surgery?

What's the life you picture for yourself? Everyday things—like morning walks on the beach. Hikes with friends. Going to shows where you aren't restricted by seating. Or lifelong things—like getting pregnant and giving birth. Keeping up with your kids' activities. Living each day, confident about the long, healthy life ahead of you.

A life where you’ve taken control of your obesity.

More than a third of Americans struggle with obesity. While it’s often the result of poor eating and exercise habits, obesity can also be affected by your genes and other conditions, like type 2 diabetes or insulin resistance. That means for many, diet and exercise alone aren’t enough.

The Wentworth-Douglass Center for Weight Management and Bariatric Surgery wants to help you live out your life’s plans, using the medical solution that’s right for you. In some cases, that means bariatric, or weight loss, surgery.



Bariatric surgery is effective.

People turn to bariatric surgery when dieting and exercise aren’t enough. And the procedure works.

After surgery, patients gradually lose over 50 percent of their excess body weight. Obesity-related conditions like type 2 diabetes, high blood pressure, and heart disease also improve, or in a majority of cases even go away.



Bariatric surgery is safe.

Every surgery has its risks. Bariatric surgery, however, is a remarkably safe procedure. With mortality rates as low as 0.1%, the benefits far exceed the risks.

You can also be confident having surgery at the Wentworth-Douglass Center for Weight Management and Bariatric Surgery, where we’ve assembled a care team that includes expert general/bariatric surgeons, certified bariatric nurses, a psychologist, nutritionists, and physical/occupational therapists. There are also ongoing support groups available to emphasize the right eating habits and exercise routines, all to help you live your best life.



Surgical procedures.

We offer two types of bariatric surgery, in which our board-certified surgeons have many years of expertise.

  • Sleeve Gastrectomy - A surgical procedure to remove a large portion of your stomach. Your new, smaller stomach will be about the size of a banana. This limits the amount of food you can eat by making you feel full after eating small amounts of food.
  • Roux-en-Y Gastric Bypass - A surgical procedure that changes how your stomach and small intestine handle the food you eat. After the surgery, your stomach will be smaller. You will feel full with less food. The food you do eat will no longer go into every part of your stomach and small intestine that absorb food. Because of this, your body will not take in all of the calories from the food you eat.



Deciding if bariatric surgery is right for you.

If you haven’t been able to sustain a healthy body weight through dieting and exercise, surgery is an option. To enter the bariatric surgery program, you need to:

  • Be at least 18.
  • Have a BMI of at least 40, or a BMI of at least 35 with other resultant health issues (called comorbidities), such as type 2 diabetes, high blood pressure, and others.

You also need to be prepared to be an active player in your success. Bariatric surgery is big decision, and shouldn’t be taken lightly. The process will take your total commitment and focus.

But we’ll be with you every step of the way. We offer all the tools and support you need to succeed and will walk you through a program that includes: an initial comprehensive analysis to ensure you’re ready for life-changing surgery, the setting of pre-op weight loss goals, behavioral modification classes, dietary instruction, physical therapy evaluation, an exercise program, preoperative testing, surgical and medical consults (i.e., cardiology, pulmonary, endocrinology, etc.) if necessary, and post-operative support groups.
