Bowel Movement Frequency Is Not Linked With Cognitive Function in Cirrhosis

Abstract

The spectrum of hepatic encephalopathy (HE) ranges from overt HE (OHE) to cognitive impairment (ie, covert) HE (CHE).1 The first-line therapy is lactulose, which is titrated to achieve ~2-3 soft/loose daily bowel movements (BM). This metric is considered dogma for practitioners despite erratic results, GI adverse events, and poor tolerance in Western countries.1 There are logistic barriers for the widespread uptake of rifaximin, the second-line therapy. Moreover, although BM frequency-directed dose titration of lactulose is the usual practice, its impact on objective cognitive performance is unclear. Our aim is to determine the impact of BM frequency on cognition in patients with/without prior OHE.
