Along with a regular medical checkup, you may have some tests to check on your health.
Your doctor will check your blood pressure, ask about any medicines you are taking, and discuss your medical history and your family's medical history. He or she will ask how active you are, whether you drink alcohol (and how much), your history of weight gain, and how often you have tried to lose weight.
Tests are available to estimate your body fat percentage (to find out about how much of your weight is fat). This is different from your BMI. With some of these tests, you may also learn your basal metabolic rate (BMR). Knowing your BMR can help your doctor or registered dietitian plan how many calories you need each day.
Doctors use BMI to help screen for unhealthy weight. If you have a BMI of 30 or higher, your extra weight—as well as unhealthy eating patterns and too little physical activity—may be putting your health in danger. If you are Asian, your health may be at risk with a BMI of 27.5 or higher.2

If you're concerned about your child's weight
If you have concerns that your child is overweight or at risk of becoming so, ask your doctor to review your child's growth charts and medical history with you. If your child's BMI and growth pattern suggest a weight problem, your doctor will give your child an exam to look for problems that can cause weight gain. He or she may ask questions about eating and exercise habits. Regular checkups will also be important over time.
