Doctor's Note - Written by Dr Muhammad Usman, MBBS

In clinical practice, 126 pounds at 5ft 6in gives a BMI of 20.2 - comfortably healthy and not a weight I would comment on clinically. At 5ft 10in the same weight gives a BMI of 18.0, which is at the underweight boundary. For taller adults I would want to understand whether this is their stable natural weight or whether there has been a change. The number 126 carries no fixed clinical meaning on its own. Height gives it meaning.
