Doctor's Note - Written by Dr Muhammad Usman, MBBS
120 pounds at 54.43 kg sits in a weight range where I see two very different groups of patients. The first are shorter adults - women of 5ft 0in to 5ft 4in - for whom this is a healthy, appropriate weight in the middle of their BMI range. The second are taller adults who have set 120 lbs as a target. For a woman of 5ft 7in, 120 lbs gives a BMI of approximately 18.8 - healthy but at the lower edge. For anyone of 5ft 8in or above, 120 lbs is underweight. Understanding which situation applies is the first thing I establish before making any assessment of this weight.
