Surgeons in the Massachusetts General Hospital Bariatric and Metabolic Surgery Program are members of the Mass General Weight Center, a multidisciplinary team of obesity experts that provide individualized consultation and innovative obesity treatment, including state-of-the-art medical and surgical programs.
Mass General surgeons perform a high volume of weight loss surgeries and achieve excellent outcomes. Each is a board-certified, Harvard Medical School-affiliated surgeon who specializes in treating patients with complex medical disorders related to obesity as well as weight disorders and metabolic disease. According to the Commonwealth of Massachusetts, 11% of our patients undergoing weight loss surgery had an illness before their surgery categorized as major or extreme, compared with a statewide figure of 2%. This specialization requires advanced training and a highly focused clinical practice.
Mass General is an accredited member of the American College of Bariatric Surgery Center Network. We offer the following surgical options for appropriate patients seeking weight loss:
In addition, the Mass General Body Contouring Program performs body-contouring procedures to remove excess skin and reshape the body to its desired proportions following weight loss surgery.
To become a candidate for surgery, you will need to be referred to the Weight Center by your primary care physician. Once referred, you will attend a Weight Center orientation and then receive a multidisciplinary consultation. If surgery is recommended, you will meet with one of our surgeons to discuss our surgical treatment programs in greater detail.In addition to our surgeons, your multidisciplinary team may include:
Accepting New Patients
Before and after your surgery, we work with your entire treatment team to design an individualized treatment plan that promotes long-term weight loss. Experts are available for counseling on nutrition, exercise and behavior modification along with medical management of related diseases.We also offer pediatric evaluation and treatments for obesity in conjunction with MassGeneral Hospital for Children.
Evaluation Your surgical evaluation begins with a Weight Center orientation. This is an one-hour lecture led by one of our obesity experts who will explain obesity, the weight center, and both medical and surgical treatments that are available. You will then receive a call to schedule an initial evaluation by a multidisciplinary team including a psychologist, dietician and in some cases, an internist specializing in obesity medicine.
Pre-surgery Nutrition Program
Your insurance company and/or your Weight Center team may require you to attend a three to six month pre-surgery program consisting of nutrition and, in some cases, psychology visits. The Weight Center has developed a pre-surgery program that helps you prepare for surgery both physically and psychologically. Nutrition education is centered on achieving pre-surgery weight loss to reduce surgical risks, understanding a healthy lifestyle and teaching healthy eating habits. The psychological component of this program is focused on providing you the tools and techniques for achieving pre-weight loss surgery goals. This program fulfills the pre-operative requirements of several insurance companies and may be recommended by our team or required before enrolling in our surgical management program.
Pre-surgery “Shrink the Liver” Diet
Studies show that rapid weight loss before bariatric surgery results in significant decrease in the size of the liver. This size decrease makes the surgery technically less difficult and faster, reducing postoperative complications. All patients who are scheduled for weight loss surgery are encouraged to lose some weight prior to surgery, and our dietitians have developed a meal replacement diet specifically designed to induce weight loss. You will meet with a dietitian to individualize this weight loss plan.
The Surgical Management Program
Preparing for weight loss surgery is important, and our program is designed to provide you with the information you will need to succeed in losing weight and in avoiding postoperative complications. You will be required to meet again with your entire team before surgery, as well as attend two group nutrition education classes. During these classes, you will be provided with instructions on your postoperative diet, and how to prepare for surgery.
The Surgical Management Program is designed to prepare you for gastric weight loss surgery and to monitor, guide and support you post-operatively. The six-month post-operative program is divided into two, three-month phases.
The first phase is Postoperative Adjustment. During this time, the Weight Center dietitian educates you about the early postoperative changes, including the diet transition from liquids to solid food. The program includes group classes for nutrition education, as well as individual psychology and nutrition visits. Your Weight Center psychologist provides support for necessary behavioral changes.
The second phase is Lifestyle Modification, which follows immediately after the Postoperative Adjustment phase. During Lifestyle Modification, the group nutrition sessions focus on the changes in nutrition and exercise that are necessary for long-term weight loss success. These sessions and individual appointments are designed to help you support your commitment to behavior change.
To keep the cost of the Surgical Management Program to a minimum, all medical and surgical visits are billed to the patient’s insurance company. Some components of the program may not be covered by insurance. Learn more about these costs

During the procedure, an endoscope with a thin, deflated balloon is inserted through the patient’s mouth and placed into the stomach. The balloon is then filled with sterile saline until it is about the size of a grapefruit, and stays in the stomach for six months. No incisions are made during this nonivasive procedure.
After six months, a nonsurgical procedure, similar to the balloon insertion, is performed to remove the gastric balloon. The balloon is deflated first and then removed.
