Son was diagnosed with GHD (stature below %1 for his age) and is scheduled to begin hormone therapy. The doctor says that he should remain active but will not specify that further in terms of type, amount, or intensity. WebMD lists risks to growth plate (hip) and that is concerning. With that in mind, what is a safe activity and at what intensity level? Currently, he runs and plays soccer. Would he be OK to continue in these sports? Should we look at swimming or anything else, instead? Would stretching place too much pressure on the growth plate? He is healthy, otherwise.
