Body mass index (BMI) can help you see if your weight is raising your risk for health problems. It uses a formula to compare how much you weigh with how tall you are.
If your BMI is in the normal range, it means that you have a lower risk for weight-related health problems. If your BMI is in the overweight or obese range, you may be at increased risk for weight-related health problems, such as high blood pressure, heart disease, stroke, arthritis or joint pain, and diabetes. If your BMI is in the underweight range, you may be at increased risk for health problems such as fatigue, lower protection (immunity) against illness, muscle loss, bone loss, hair loss, and hormone problems.
BMI is just one measure of your risk for weight-related health problems. You may be at higher risk for health problems if you are not active, you eat an unhealthy diet, or you drink too much alcohol or use tobacco products.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
