Limitations of BMI
Although BMI is often a practical indicator of healthy weight, it is
not suited for every person. Specific groups should carefully
consider their BMI outcomes, and in certain cases, the measurement
may not be beneficial to use.
Gender
The development and body fat composition of girls and boys vary with
age. Consequently, a child's age and gender are considered when
evaluating their BMI.
Age
In aging individuals, increased body fat and muscle loss may cause
BMI to underestimate body fat content.
Muscle
BMI may misclassify muscular individuals as overweight or obese, as
it doesn't differentiate muscle from fat.
Pregnancy
Expectant mothers experience weight gain due to their growing baby.
Maintaining a healthy pre-pregnancy BMI is advisable to minimise
health risks for both mother and child.
Race
Certain health concerns may affect individuals of some Black and
Asian origins at lower BMIs than others. To learn more, it is
advised to discuss this with your GP or practice nurse.
