What is BMI Index?

Body Mass Index (BMI) is a measurement of a person’s weight with relevancy to his or her height. It's more of an indicator than an instantaneous measurement of a person’s total body fat.

BMI, more often than not, connects with total body fat.. This implies that because the BMI score increases, so does a person’s total body fat. It's widely used as a general indicator of whether someone incorporates a healthy weight for his or her height. Specifically, the worth obtained from the calculation of BMI is employed to categorize whether an individual is underweight, normal weight, overweight, or obese betting on what range the worth falls between. These ranges of BMI vary supported factors like region and age, and are sometimes further divided into subcategories like severely underweight or very severely obese. Being overweight or underweight can have significant health effects, so while BMI is an imperfect measure of healthy weight, it's a useful indicator of whether any additional testing or action is required.

Formula for calculating BMI Index

BMI in a person is calculated by the employment of a mathematical formula. It may be estimated using tables within which one can match height in inches to weight in pounds to estimate BMI. There are convenient calculators available on websites that help calculate BMI similarly.

BMI = (Weight in Kgs) divided by (Height in m²)

A normal BMI score is one that comes between 18.5 and 24.9. This means that someone is within the traditional weight range for his or her height. A BMI chart is employed to categorize someone as underweight, normal, overweight or obese.

Risks of having High BMI index or being overweight

BMI is employed by healthcare professionals to screen for overweight and obese individuals. The BMI is employed to assess a person’s health risks related to obesity and overweight. For example people with a high BMI are at risk of :-

• Higher levels of LDL cholesterol, which is broadly acknowledged "bad cholesterol," lower levels of HDL cholesterol, admitted to be good cholesterol in moderation, and high levels of triglycerides
• Type II diabetes
• Stroke
• Osteoarthritis which is a type of joint disease caused by breakdown of joint cartilage
• Sleep Apnoea & breathing problems
• Certain cancers diseases like endometrial, breast, colon, kidney, gallbladder, liver.
• Mental illnesses like clinical depression, anxiety, and others
• High blood pressure
• Body pains & difficulty with particular physical functions
• Generally, an increased risk of mortality accordance to those with a healthy BMI
• Coronary heart disease
• Gallbladder disease
• Low quality of life

BMI, however, is one amongst the tools that are accustomed to calculate healthy risk. Other factors like blood pressure, cholesterol level, glucose level, case history of heart condition, age, gender, waist circumference, level of physical activity, menopause status, smoking status etc. also are taken into consideration while assessing health risk.

Risks of having Low BMI index or being underweight

Being underweight has its own related risks, mentioned below:

• Malnutrition, vitamin deficiencies, anaemia (lowered ability to carry blood vessels)
• Osteoporosis is a name of a disease that causes bone weakness, increasing the risk of breaking a bone
• A decrease in immune function
• Growth and development issues, commonly in children and teenagers
• Possible reproductive problems for women due to hormonal imbalances that can disturb the menstrual cycle. Underweight women also have a higher risk of miscarriage in the first trimester
• Generally, an increased risk of mortality as to those with a healthy BMI
• Potential complexities as a result of surgery

In some cases, being underweight is an indication of some underlying condition or disease like anorexia nervosa, which has its own risks. Consult your doctor if you're thinking that you or someone you recognize is underweight, particularly if the explanation for being underweight doesn't seem obvious.

Ponderal Index

The Ponderal Index (PI) is comparable to BMI therein it measures the leanness or corpulence of an individual supported their height and weight. The most difference between the PI and BMI is that the cubing instead of squaring of the HEIGHT within the formula (provided below). While BMI are often a useful gizmo when considering large populations, it's not reliable for determining leanness or corpulence in individuals. Although the PI suffers from similar considerations, the PI is more reliable to be used with very tall or short individuals, while BMI tends to record uncharacteristically high or low body fat levels for those on the acute ends of the peak and weight spectrum.

PI = (Weight in kilograms) divided by (Height in metres cubed)
