Feed thickening is widely employed to reducing vomiting and regurgitations in symptomatic term infants; with regard to the preterm population, however, little data is currently available. We have previously investigated the efficacy of thickened fortified human milk on preterm infants suffering from GER symptoms (frequent regurgitations, desaturations, bradycardia), observing no benefits. Furthermore, standard human milk fortification itself has been shown to increase GER frequency in preterm infants.
