Obesity is a medical condition that causes an individual to gain excessive body weight, particularly in terms of fat. The situation becomes severe with time, up to the extent where it starts to cause significant physical discomfort, mental trauma and attract several other medical conditions. Often it cannot be cured by any of the conventional means and weight loss surgery in India remains the only plausible solution for the same.
Every medical condition needs a particular measure in some aspect order to qualify it for the same. In case of obesity, it is done in terms of Body Mass Index or more commonly known as BMI. BMI was first introduced by the Belgian anthropometrist Adolphe Quetelet in the 19th century.
BMI is calculated by dividing an individual’s weight by the square of his height. In metric terms, it can be obtained by dividing the body weight in kilograms by the square of height in meters. The result of this formula gives the weight status of an individual and easily be tabulated as follows.
BMI combined with an individual’s age and gender, can estimate the body fat percentage. It is a very important tool to find the weight status of an individual along with whether or not he needs weight loss surgery in India.
The Asian population experiences adverse health consequences at a comparatively lower BMI as compared to Caucasians. Thus, several Asian countries have their own cut off for obesity. For instance, Japan considers a BMI greater than 25 as obese, the count changes to 28 in the case of China.
Even though it does not account for the entire fat distribution in the body or muscle mass, in today’s world, BMI is considered as one of the widely used tools for determining the healthy body weight and any deviation from normal.
It holds true for most of the adult individuals globally. Some of the exceptions would be body builders, strenuous sportsmen and pregnant women, who gain reasonable extra weight for obvious reasons without qualifying for being fat or clinically obese.
