At 5ft 8in the BMI is 18.1, just below the underweight threshold. For adults of 5ft 7in or taller, 120 pounds begins to fall into the underweight range.

120 pounds is a weight I treat carefully in clinical practice. For a woman of 5ft 4in it gives a BMI of 20.6, which is perfectly healthy. For a woman of 5ft 7in the BMI is 18.7, just within healthy, and I would monitor. For anyone taller than 5ft 8in, this weight is underweight by NHS/WHO standards and warrants discussion. The key question I ask is whether the patient has always been this weight or has recently lost weight, as the latter requires investigation.
