Why Do I Need to Know My BMI?

A BMI of 25 or above is a risk factor for overweight and obesity related diseases such as cardiovascular disease, osteoarthritis, some types of cancer and type II diabetes. A low BMI — under 18 — increases your risk for osteoporosis or may be a sign of a health problem. If you have a BMI of above 27 or below 18, you should see your doctor to have any additional risk factors assessed and for guidance on how to lose (or gain) weight.
