catch-up growth

Etymology: L, capere + As, uf, gruowan
an acceleration of the growth rate following a period of growth retardation caused by a secondary deficiency, such as acute malnutrition or severe illness. The phenomenon, which routinely occurs in premature infants, involves rapid increase in weight, length, and head circumference and continues until the normal individual growth pattern is resumed. The severity, duration, and developmental timing at which the deficiency occurs may result in some growth inadequacy or permanent deficit, especially in such tissue as the brain.

catch-up growth

The accelerated growth of a malnourished, premature, or small neonate during the first two years of life. This growth enables the child to attain a normal size.
