How to calculate BMI?

Assalamualaikum.

So today I want to share some info about BMI. What is it? Body mass index. This index is a standard guide to classify who are in what range between underweight, normal or ideal, overweight and obese.

Because I attached to Diabetic Clinic just now under supervision of Sister Zaidah and Nurse Ros.
So much things i learnt today from screening diabetic retinopathy, fundoscamera, staging etc.

But i just want to share how to calculate ideal weight range for individu in normal range calculated BMI

Weight range - ?
Height - 1.57m
BMI normal range - 18-23

Lower limit weight range
= 1.57x1.57x18
= 46

Upper limit weight range
= 1.57x1.57x23
= 59

therefore ideal normal weight range of this patient is = 46-59kg
