Lactulose-based hepatic encephalopathy (HE) treatment requires bowel movements/day(BMs) titration, which is improves with Bristol stool scale (BSS) incorporation. Dieta-App evaluates AI-based BSS(AI-BSS) with stool images. Initially, controls(N=13) and cirrhosis patients on lactulose/not(n=33) were trained on the App. They entered self-reported-BSS(self-BSS) with AI-BSS communicated. Lactulose dose changes were tracked. A subset (n=12) was retested with AI communication blocked. Most subjects were comfortable with the App. Self/AI-BSS and lactulose dose/AI-BSS correlation increased with App use. AI-BSS communications improved insight into self-BSS over time. Dieta-App to gauge stool AI characteristics was acceptable and increased insight into lactulose dose and BSS in cirrhosis.
