Body Mass Index(BMI) and BMI Calculator

Nowadays, if you visit your physician, you may hear this term “BMI” and one more thing is that you need to lower your BMI.


What is BMI?

Body Mass Index is actually a measurement of body size. It determines a person’s body fat based on his or her weight and height. It does not measure a person’s total body fat(percentage), but it is one kind of indicator.

With BMI, you get to know whether you are underweight, healthy weight or overweight. If your BMI is outside of the healthy range, then health risks may increase significantly. If a person is overweight then he is at risk of high blood pressure, type-2 diabetes etc.

If a person is underweight, then it can lead to anemia, malnutrition etc.


How to calculate BMI?


BMI is calculated on the mathematical formula.


BMI= Weight in KG /  (Height in meter)2




Above formula gives the result as per below chart.

BMI Result
Below 18.5 Underweight
18.5 – 24.9 Normal
25.0 – 29.9 Overweight
30.0 plus Obese

This chart can be used to categorize a person with overweight, normal or obese.



Clinical importance of BMI

Those with high BMI are at risk of:

hypertension, or high blood pressure
dyslipidemia, which involves high LDL cholesterol, low HDL cholesterol, or high levels of triglycerides
type 2 diabetes
coronary heart disease
gallbladder disease
sleep apnea and respiratory problems
some cancers, including endometrial, breast and colon cancer
Carrying extra weight as a child or teenager can also pose significant health risks, both during childhood and into adulthood.


BMI does not account for bone and muscle mass as height and weight are the only factors. Somebody with more muscle mass and healthy body fat could have an overweight BMI score.

BMI together with other measures like waist-height-ratio, waist-hip ration, body fat, and lean body mass can help to assess more accurately the health risks associated with an individual weight.
