microscopic colitis

A collective term for collagenous colitis and lymphocytic colitis. Once considered rare gastrointestinal disorders, these conditions are now known to be relatively common and should be considered in the differential diagnosis of persistent watery diarrhoea without blood. Most cases resolve spontaneously but treatment with budesonide and bismuth subsalicylate may be necessary.
