Weight Loss: Treatments & Surgical Options

Obesity is defined as having a body mass index (BMI) of 30 or greater. Obesity is a serious medical condition that can have a negative effect on your health.

Obesity rates have more than doubled since 1980, and nearly 500 million adults worldwide are considered obese.1 In the United States alone, obesity affects nearly 65 percent of adults and is the second leading cause of preventable death.2

Obesity often leads to other serious health problems such as heart disease, stroke, cancer, arthritis, high blood pressure, sleep apnea and diabetes—conditions that can cause early death or disabilities.2

The good news is even modest weight loss can reduce your risk for these diseases or outcomes.2

BMI Classification Health Risk
Under 18.5 Underweight Minimal
18.5-24.9 Normal Weight Minimal
25-29.9 Overweight Increased
30-34.9 Obese High
35-39.9 Obese (Class II) Very High
40 and over Morbidly Obese (Class III) Extremely High

Obesity Solutions
Obesity treatments often focus on weight loss as well as minimizing or eradicating some of the related health problems. Your doctor can help you decide which treatment or surgical option is best, based on your weight and overall health. Some of the options for weight loss may include dietary changes, exercise, lifestyle changes, medication or surgery.

Surgical Options
Surgery for weight loss is known as bariatric surgery. Bariatric surgery focuses on reducing the size of the stomach in order to reduce the body's ability to absorb and store calories. The most common bariatric procedures are Roux-en-Y gastric bypass (RYGB), gastric sleeve surgery and gastric banding. 














If you are considering having bariatric surgery, you may be a candidate for minimally invasive da Vinci Surgery.

Why da Vinci Surgery? 
Instead of the large abdominal incision used in open surgery, da Vinci surgeons make just a few small incisions—similar to traditional laparoscopy. The da Vinci System features a magnified 3D high-definition vision system and special, wristed instruments that bend and rotate far greater than the human wrist and fingers can. These features enable your surgeon to operate with enhanced vision, precision, dexterity and control.

As a result of da Vinci technology, da Vinci Surgery offers the following potential benefits:

  • Low rate of complications3, 4, 5, 6
  • Low rate of wound infection3, 4, 5
  • Short hospital stay3, 4, 5, 6
