BMI, or Body Mass Index, is essentially a quantitative measurement of weight in proportion to your height. Obviously a very tall person can have a certain weight and be lean, but the same weight would not be considered healthy for a short person.
Body Mass Index is calculated the following formula:
BMI = Weight / Height(squared)
The weight is in kilograms
The Height is in meters
Dividing your weight, by a square value of your height in meters would give you your BMI.
The following cutoffs are used for BMI values:
Less than 18.5 = Underweight
18.5 to 24.9 = Normal weight
25 to 29.9 = Overweight
30 to 39.9 = Obese
40 and up = Extremely Obese.
Although BMI is used a lot in healthcare, it has some major pitfalls and is not always accurate. For example, someone who is an athlete or a weight lifter may have a BMI of 27, but be in top physical shape and be healthy. BMI does not account for body fat percentage, muscle mass, bone structure/build, etc.
Therefore BMI is not always an accurate assessment of a patient's health and weight.
should be able to assess if your weight and BMI are appropriate for you. I recommend you speak to your primary care physician
regarding your weight and BMI.
