catch-up growth
Accelerated growth following a period of growth restriction, allowing return to normal growth trajectory.
Full Definition
Catch-up growth refers to a period of accelerated linear growth that occurs when conditions limiting normal growth are corrected, allowing a child to return to their genetic growth potential. This phenomenon is commonly observed in premature infants after NICU discharge, in children recovering from malnutrition, or following treatment of chronic diseases that impaired growth. The growth velocity during catch-up periods typically exceeds normal rates for age, and the extent of catch-up depends on factors such as the duration and severity of the growth restriction, the age at which it occurred, and the effectiveness of corrective interventions.
Usage
Usage note: Document growth velocity and specify corrected age when applicable for premature infants.
