Bile acid malabsorption, known also as Bile acid diarrhea, is a cause of several gut-related problems, the main one being chronic diarrhea. It has also been called Bile acid-induced diarrhea, Cholerheic or Choleretic enteropathy and Bile salt malabsorption. It can result from malabsorption secondary to gastrointestinal disease, or be a primary disorder, associated with excessive bile acid production. Treatment with bile acid sequestrants is often effective. ==Classification== Bile acid malabsorption was first recognized in patients with ileal disease. When other causes were recognized, and an idiopathic, primary form described, a classification into three types was proposed: * Type 1: Bile acid malabsorption, secondary to ileal resection, or ileal inflammation (e.g. in Crohn's disease) * Type 2: Idiopathic bile acid malabsorption, Primary bile acid diarrhea * Type 3: Secondary to various gastrointestinal diseases including cholecystectomy, vagotomy, small intestinal bacterial overgrowth, radiation enteropathy, celiac disease, chronic pancreatitis, etc. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bile acid malabsorption」の詳細全文を読む スポンサード リンク
