Doctor’s Note
Dr Muhammad Usman, MBBS
13.5 stone is a weight where clinical context matters significantly. For a 5ft 6in adult, the BMI of 30.4 technically meets the obesity definition, but only just. In clinical practice, what I focus on at this weight is metabolic health rather than the category label. A patient at 13.5 stone with normal blood pressure, blood sugar, and cholesterol is in a different risk category to one with elevated markers across the board. The number is a starting point for a conversation, not the end of one.
