Body Mass Index (BMI) is the calculation of a body's height and weight in a numerical that tells if a person's weight is appropriate or not. BMI uses equations to measure a body's fat that determines if a person has a healthy or unhealthy weight. High BMI indicates too much fat on a body, whereas a low BMI signifies little body fat on a body. People with higher BMI have more chances of developing some serious disorders such as heart problems, diabetes, and high blood pressure. Whereas, very low BMI leads to health issues like reduced immunity, bone loss, anemia, etc.
Though BMI is beneficial in displaying the weight problems in kids and adults, it does have some limitations.

At times, it also underestimates and miscalculates the body fat in older adults or people with less muscle mass. Even if you have health insurance, it is really important to keep your BMI in check for your well-being in the longer run.
Physicians use Body Mass Index to track the weight status to address health risks and issues in individuals.
