Defining Obesity
For adults, the measure most commonly used to determine which individuals are most likely to have weight-related illnesses is the Body Mass Index (BMI).
BMI is used because, for most adults, it correlates with the amount of body fat. It is important to remember that although BMI correlates with amount of body fat, it does not directly measure body fat. It also does not take into account how your body fat is distributed (for example, people who collect fat around the abdomen and waist are at higher risk of health problems).
Even though BMI is not a perfect measure of ‘fatness’, it remains one of the best clinical indicators available to help doctors screen for weight categories which are likely to lead to health problems.

If you are obese, your weight poses significant health risks. We recommend that you consult your doctor and if the service is available, enroll in a medically supervised weight loss program.
If you have struggled with severe obesity and obesity-related physical problems, bariatric surgery may be right for you. However, not everyone qualifies for bariatric surgery.
