AB The  terms  acid  peptic  diseases,  peptic  diseases,  or  acid-related  disorders  are  used  synonymously  to  describe  conditions  that  involve  gastric  acid  and  pepsin  in  their  pathogenesis;  they  refer  to  a  number  of  disorders  including  esophagitis,  gastritis,  peptic  ulcer  disease,  and  duodenitis.  Gastritis  is  a  condition  diagnosed  histologically,  not  clinically  or  radiologically.1-5  It  is  characterized  by  the  presence  of  inflammatory  cells  and  is  often  found  to  be  present  in  biopsies  taken  from  gastric  mucosa  that  appears  normal  at  endoscopy.  Some  forms  of  chronic,  severe  gastritis  may  destroy  mucosal  elements,  resulting  in  atrophic  gastritis  and  intestinal  metaplasia,  which  in  some  forms  may  be  preneoplastic.  Although  gastritis  and  ulcer  disease  may  occur  as  stand-alone  entities,  they  are  often  part  of  a  continuum  of  disease.2,3,6  A  special  case  is  that  of  Helicobacter  pylori,  an  important  cause  of  gastritis  and  peptic  ulcer  disease  discussed  separately.
