What does your number mean?

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults.

BMI values are age-independent and the same for both sexes.
The health risks associated with increasing BMI are continuous and the interpretation of BMI gradings in relation to risk may differ for different populations.

As of today if your BMI is at least 35 to 39.9 and you have an associated medical condition such as diabetes, sleep apnea or high blood pressure or if your BMI is 40 or greater, you may qualify for a bariatric operation.

If you have any questions, contact Dr. Claros.
