Bariatric Surgery Program

Take the next step in transforming your health

Millions of Americans struggle with their weight, but the battle to overcome obesity can be especially difficult. There may be many contributing factors including genetics, environment, metabolism and even certain medications. Weight-loss surgery or "bariatric surgery" may be the most effective treatment for severe obesity and the best way to get you back on track for a healthier lifestyle.

When considering bariatric surgery, it's important to find a highly qualified, integrated team, like the experts at Dartmouth Hitchcock Medical Center and Dartmouth Hitchcock Clinics. Our providers work on multi-disciplinary teams to ensure comprehensive care for all your weight management needs—from the first steps, through surgery and beyond.

Our Bariatric Surgery Program offers several different procedures, which we will discuss in the introductory session. Your surgeon will help determine which is right for you.

Requirements for surgery

In order to consider bariatric surgery, you must first meet minimal criteria as proposed by the National Institutes of Health (NIH). These criteria include:

  • A Body Mass Index (BMI) over 40.
  • A BMI between 35 and 40 and at high risk for serious obesity-related conditions that could cause death, such as sleep apnea, heart problems or severe diabetes.
  • Failed attempts at traditional weight loss methods.
  • Physical problems caused by obesity that interfere with lifestyle or body size that causes severe problems with work, family roles, even walking.

Learn more about bariatric surgery from The American Society for Metabolic and Bariatric Surgery (ASMBS).

Bariatric surgery can help

Obesity is a disease and is connected to many medical problems. After bariatric surgery, patients usually lose about 50-66% of their excess body weight, which equals about 33% of their overall weight. If you lose weight and keep it off, your medical conditions are most likely going to improve. Bariatric surgery may:

  • Eliminate sleep apnea in more than 90 percent of patients.
  • Improve shortness of breath and asthma.
  • Reduce heartburn and other reflux symptoms.
  • Improve outlook and self-esteem.
  • Improve blood pressure and cholesterol levels.
  • Reduce diabetes medication, like insulin and oral medications.
  • Reduce the risk of heart disease.
  • Reduce degenerative joint disease, arthritis and back pain symptoms.

When you join our Bariatric Surgery Program, we are with you throughout your entire journey on a path to a healthier life. Our after-surgery plan includes support and education from our nutritionists, nurses and providers.
