Alex is a 10 year old boy who presents to your office for a sports physical accompanied by his mother. He saw you 2 months ago for immunizations, which are up to date. At that time, his history and physical exam were unremarkable.
As Alex's height and weight are being measured, his mother comments that he seems to have gained quite a bit of weight in the past year or so. She asks if this could be a problem. What is the most appropriate response?
A. "It's probably baby fat, he should outgrow this." B. "Being overweight can be a problem. Let's see how his height and weight compare to other boys his age."
