AB Gastroesophageal  reflux  (GER),  defined  as  the  passage  of  gastric  contents  into  the  esophagus,  occurs  on  a  daily  basis  as  a  normal  process  in  infants,  children,  and  adults.  Most  episodes  of  physiologic  reflux  are  transient,  asymptomatic,  and  reach  only  the  distal  esophagus.  Gastroesophageal  reflux  disease  (GERD)  is  distinguished  by  reflux  into  the  esophagus  resulting  in  well-defined  symptoms  or  medical  problems  (see  Chapter  12).  When  children  present  with  atypical  complaints  or  extraesophageal  symptoms,  testing  may  be  necessary  to  document  the  presence  or  absence  of  pathologic  reflux,  or  the  association  between  reflux  events  and  specific  symptoms.1
