AB Gastrointestinal  (GI)  bleeding  is  an  important  cause  of  mortality  for  emergency  department  (ED)  and  critically  ill  patients.  Upper  gastrointestinal  bleeding  (UGIB)  is  defined  as  a  gastrointestinal  bleeding  source  proximal  to  the  ligament  of  Treitz,  whereas  lower  gastrointestinal  bleeding  (LGIB)  is  defined  as  bleeding  distal  to  the  ligament  of  Treitz  (Figure  23-1).  This  chapter  discusses  the  epidemiology,  clinical  presentation,  and  etiology  of  UGIB  and  LGIB,  followed  by  a  discussion  of  the  management  of  patients  with  GI  bleeding.
