Pediatric growth hormone deficiency can be congenital (present from birth, sometimes with no identified cause) or can arise from a structural pituitary problem, and it is generally the primary and most established indication for GH therapy historically. Genetic conditions such as Turner syndrome and Prader-Willi syndrome represent a separate but related category affecting growth through additional mechanisms.
Adult-onset deficiency, by contrast, is typically acquired rather than lifelong — most often resulting from a pituitary tumor, pituitary surgery, radiation therapy, or traumatic brain injury affecting the gland later in life, after normal childhood growth has already completed.
In children, the clinical picture centers on growth itself: a height that falls below expected curves for age, or a growth rate that slows noticeably year over year, is usually the first thing a pediatrician or parent notices, sometimes alongside delayed puberty and delayed bone age on imaging.
In adults, because bones can no longer respond to growth hormone by lengthening, the presentation is far less specific — documented literature associates it with reduced lean muscle mass, increased visceral fat, fatigue, reduced exercise capacity, lower bone mineral density over time, and cholesterol changes, all of which overlap heavily with normal aging and other conditions.
Pediatric diagnosis and monitoring rely heavily on growth-curve tracking over an extended treatment period, tracking height percentile and growth velocity against standardized references alongside lab testing. This gives clinicians an additional, highly visible signal that adult cases simply do not have.
Adult diagnosis and monitoring instead rely on lab values — IGF-1 levels, stimulation testing results, and metabolic markers — combined with clinical assessment, since there is no equivalent growth-curve signal once skeletal maturity is reached.
Despite these differences, both pediatric and adult HGH use remain strictly prescription-only and physician-supervised in the UAE and internationally, requiring confirmed diagnosis before any treatment decision and ongoing monitoring throughout.
