BMI is a screening measure rather than a diagnosis. At 5ft 6in, 6 stone gives a BMI of about 13.5, but the result changes with height. Adult BMI does not provide a complete assessment of health, and children should be assessed using age- and sex-specific growth-chart information rather than adult BMI categories. Speak with a GP if you have personal concerns about a weight change or health symptoms.
