Abstract:
Bile acid diarrhea (BAD) is a socially debilitating disease. Typical symptoms include loose stools, urgency, and high stool frequency. Recently, we reported the superior efficacy of the glucagon like-peptide 1 receptor agonist (GLP-1RA) liraglutide (administered subcutaneously once daily) in reducing daily bowel movements compared with the traditionally used bile acid sequestrant colesevelam (considered the standard of care). This has generated proposals of testing longer acting and more potent GLP-1RAs for treating BAD. Here, we present a patient with severe BAD who experienced minimal effect of the once-weekly administered GLP-1RA semaglutide, but total remission of BAD symptoms during treatment with liraglutide.

Glucagon-like Receptor Agonists
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...
