catch-up growth
Accelerated growth that occurs when children recover from growth-inhibiting conditions, allowing them to return to their genetic growth trajectory.
Full Definition
Catch-up growth refers to a period of accelerated linear growth that occurs when a child recovers from a condition that previously impaired their growth. This phenomenon is commonly observed after treatment of underlying conditions such as malnutrition, chronic illness, hypothyroidism, or celiac disease. During catch-up growth, children may grow at rates significantly above their previous growth velocity, sometimes reaching 150-200% of the expected growth rate for their age. The potential for catch-up growth depends on factors including the child's age, the duration and severity of the growth-inhibiting condition, and the timing of intervention. Complete catch-up may not always occur, particularly if the growth restriction was prolonged or occurred during critical growth periods. This concept is important in pediatric endocrinology for predicting outcomes and determining when intervention may be necessary.
