Excessive delivery of bile salts to certain parts of the bowel (usually the colon) can trigger a secretory diarrhea.
(1) secretory diarrhea
(2) exclusion of other causes of diarrhea
(3) presence of a condition associated with bile salt diarrhea (see below)
(4) correction by use of bile sequestration resin or by correction of cause of excessive bile salt delivery
Conditions associated with a defect in the terminal ileum and managed by bile sequestration:
(1) Crohn's disease
(2) ileal resection
(3) radiation enteritis
Conditions associated with an intact terminal ileum and maneged by bile sequestration:
(2) hereditary defect in ileal absorption of bile salts associated with SLC10A2 mutation
Conditions associated with intact terminal ileum and managed by correction of cause:
(1) drug-induced with chenodeoxycholic acid or ursodeoxycholic acid: treat by reducing the dose
(2) cholecystocolic fistula: treat by taking down the fistula
(3) possibly bacterial overgrowth: treat with broad spectrum oral antibiotics and/or bile salt sequestration
