Hormones and postnatal adaptation to enteral nutrition
1983
Aynsley-Green, A.
There is increasing evidence that normal feeding of neonates stimulates surges in their circulating gut, pancreatic, and pituitary hormones. Furthermore, those hormones may, in turn, induce the adaptive events that equip the newborn infant for the profound change in his mode of feeding that occurs postnatally (i.e., changing from umbilical cord nutrition, directly from the mother, to oral feeding and gastrointestinal absorption). Recent data are presented and reviewed on: postnatal surges in plasma levels of gut hormones in preterm and term infants at birth; and the effect of breast milk and cow's milk formula on plasma hormone levels, especially in preterm infants. A number of questions are posed, the answers to which may have significant practical importance in defining the optimum form of nutrition for various groups of neonates. (wz)
