[The role of bile acids in the pathogenesis of chronic diarrhea].

Chronic diarrhea syndrome results from excess colonic bile acids. Fibroblast growth factor 19 (FGF19), produced in the ileum is response to bile acid absorption, regulates hepatic bile acids synthesis. Bile acid malabsorption can be found in various gastrointestinal conditions: the greatest losses bile acids with excrements were marked at patients with surgical resection of terminal ileum. The maintenance in daily colonic excess bile at patients with postholecystectomy exceed more than in three times the indicators noted at control subjects, but at the patients with irritable bowel sindrom did not exceed the norm. Effective remedies in treatment chologenic diarrhea were bile acid sequestran.
