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.
Body mass index, or BMI, measures the relationship between height and weight. It's a way to evaluate whether a person is of normal weight, overweight or underweight. Healthy adults usually fall between 18.5 and 24.9 on the BMI chart. A BMI below 18.5 signals a problem may exist, while a BMI below 17.5 -- especially in adults -- is usually present in people suffering from anorexia nervosa.
