Bariatrics is a field of medicine specializing in the prevention, diagnosis and treatment of conditions related to obesity. Obesity is a medical condition in which an individual has excess body fat and a body mass index (BMI) over 30. There are three classes of obesity
- Class 1: BMI 30-34.9
- Class 2: BMI 35-39.9
- Class 3: BMI 40+
Because obesity is a leading cause of preventable chronic diseases, including heart disease, bariatrics focuses on improving health primarily through diet and exercise.
In some cases, bariatric treatment involves bariatric surgery, which is the surgical removal of excess fat.
