Like hypertension or diabetes, obesity is influenced by genetic, metabolic and environmental factors. UT Southwestern Medical Center ascribes to guidelines developed by the National Institutes of Health (NIH) and other research institutions that indicate a body mass index (BMI) greater than 30 defines obesity, while a BMI greater than 40 represents severe or morbid obesity. A BMI greater than 50 is frequently accompanied by multiple medical complications, and our specialists offer effective procedures needed to treat patients with these conditions.
According to the Centers for Disease Control and Prevention, about 30 percent of adults in the U.S. or more than 60 million people, are obese. About 65 percent of Americans are overweight or obese.
Research at UT Southwestern Medical Center and other institutions have indicated that several factors contribute to the likelihood of becoming overweight or obese, including:
- Behavioral traits
- A person’s individual environment
- Cultural attitudes
- Financial condition
- Heredity and genetics
Along with a healthy diet, exercise is an important method to control weight. Because people tend to consume more calories than are needed for everyday activities, exercise plays an important role in burning off calories and preventing excess weight gain.
For individuals who want to lose a significant amount of weight, researchers and nutritional experts recommend consulting a physician before beginning a weight-loss program. In addition to maintaining a healthy diet and regular exercise regimen, weight-loss surgery may be a valuable solution to not only reducing weight, but also reversing or eliminating obesity-related health risks.
