What is BMI and why is it so important to your health? BMI stands for body mass index, and for most people, it's a pretty reliable gauge of body fat. It's also a helpful tool for a doctor to assess your risk for weight-related health problems, including heart disease. As your BMI increases, so does the risk for heart attack and stroke. Extra body fat can also contribute to higher blood pressure. It can also interfere with the body's ability to process insulin, which may result in type 2 diabetes.
