BMI stands for Body Mass Index. This is a numerical value of your weight in relation to your height. A BMI between 18.5 and 25 kg/mÂ² indicates a normal weight. A BMI of less than 18.5 kg/mÂ² is considered underweight. A BMI between 25 kg/mÂ² and 29.9 kg/mÂ² is considered overweight. A BMI of 30 kg/mÂ² or higher is considered obese. Excess weight increases the heart's work. It also raises blood pressure and blood cholesterol and triglyceride levels and lowers HDL (good) cholesterol levels.
If your BMI is less than 18.5, you are in the underweight category. Talk to your doctor to find out if your weight is a symptom of a medical problem. A registered dietitian can help you learn about healthy eating. If your BMI is between 18.5 and 24.9, you are in the recommended weight range for your height. But your health may still be at risk if you are not getting regular physical activity and practicing healthy eating. If your BMI is 25 to 29.9, you are in the overweight category.
