Reflujo gastroesofágico en bebés - Overview

Nombres alternativos

Reflujo en los bebés

Definición:

Es una afección en la cual los contenidos estomacales se devuelven desde el estómago hasta el esófago (el conducto que va desde la boca hasta el estómago) después de comer. Este artículo aborda el reflujo en bebés.

Causas:

Cuando una persona come, el alimento pasa desde la garganta al estómago a través del esófago. El esófago se conoce como tubo de paso de los alimentos o de la deglución.

Una vez que el alimento está en el estómago, un anillo de fibras musculares impide que éste regrese al esófago. Estas fibras musculares se denominan esfínter esofágico inferior o EEI.

Si este músculo no se cierra bien, el alimento se puede devolver al esófago y esto se denomina reflujo gastroesofágico (ERGE).

En los bebés, es normal que se presente una pequeña cantidad de reflujo gastroesofágico. De hecho, más de la mitad de los bebés tendrá reflujo durante los primeros tres meses.

El reflujo persistente con vómito frecuente lleva a la irritación del esófago y melindres en el bebé. El reflujo asociado con pérdida de peso o el reflujo que ocasiona dificultad respiratoria se considera anormal.
