Traditional Approach:   Secretory -- poisoned mucosal villi -- "the sieve" Cytotoxic -- destroyed mucosal villi -- "the shred" Osmotic -- malabsorption -- "the pull" Inflammatory -- edema, motility -- "the push" Lots of overlap, difficult to apply to clinical signs and symptoms.   Bedside Approach: Fever/No Fever, Bloody/No Blood   Non-bloody, febrile -- most likely viral Non-bloody, afebrile -- may be viral Bloody, febrile -- likely bacterial Non-bloody, afebrile -- full stop.  Eval for Hemolytic Uremic Syndrome   Workup   Ask yourself -- again -- why is this not... appendicitis-torsion-intussusception-etc. Admit sick children, but most go home, so...   Non-bloody, febrile -- no workup necessary; precautionary advice  Non-bloody, afebrile -- be more skeptical, but generally same as above Bloody, febrile -- stool culture, follow up; do not treat empirically unless septic and admitted.  Culture will dictate treat/no treat/how. Bloody, afebrile -- evaluate for hemolytic uremic syndrome, especially if under 5 years old: CBC, chemistries, UA, stool culture   Evaluate Hydration Status                 Selected References Khan WA et al.
