Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.
