High prevalence of functional dyspepsia in nonalcoholic fatty liver disease: a cross-sectional study.

Background: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated.

Objective: To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease.
