AB  - Belching  (eructation)  is  the  involuntary  or  voluntary  release  of  gas  from  the  stomach  or  esophagus.  It  occurs  most  frequently  after  meals,  when  gastric  distention  results  in  transient  lower  esophageal  sphincter  (LES)  relaxation.  Belching  is  a  normal  reflex  and  does  not  itself  denote  gastrointestinal  dysfunction.  Virtually  all  stomach  gas  comes  from  swallowed  air.  With  each  swallow,  2–5  mL  of  air  is  ingested,  and  excessive  amounts  may  result  in  distention,  flatulence,  and  abdominal  pain.  This  may  occur  with  rapid  eating,  gum  chewing,  smoking,  and  the  ingestion  of  carbonated  beverages.  Evaluation  should  be  restricted  to  patients  with  other  complaints  such  as  dysphagia,  heartburn,  early  satiety,  or  vomiting.
