Constitutional delay of growth and puberty (CDGP) is a term describing a temporary delay in the skeletal growth and thus height of a child with no physical abnormalities causing the delay. Short stature may be the result of a growth pattern inherited from a parent (familial) or occur for no apparent reason (idiopathic). Typically at some point during childhood, growth slows down, eventually resuming at a normal rate. CDGP is the most common cause of short stature and delayed puberty.

CDGP is not associated with increased mortality because it is a variant of normal growth rather than a disease. However, in some affected individuals, it can be associated with significant psychological stress, resulting in poor self-image and social withdrawal. In recent years, researchers have also found that individuals with CDGP may be at increased risk for reduced bone mass in adulthood because of the delay in sex steroid influence on bone accrual during adolescence.
