OBJECTIVE: Functional constipation (FC) is a common condition in which the gut microbiota composition plays a fundamental role. The increasing knowledge on the role of gut microbes in the regulation of gut motility and stool consistency has allowed reconsidering, with a new scientific-based approach, the possibility to target the composition of intestinal bacterial populations for FC treatment. In this review, we evaluate recent attempts that used prebiotics, natural fibers or probiotics to treat FC, with a deep microbiome-based focus.

MATERIALS AND METHODS: This is a literature review of articles published in Medline, Web of Science, and the Cochrane Library. Studies on FC in adults and children were identified using the following terms: constipation AND probiotics OR prebiotics OR synbiotics PR fibers OR microbiome OR microbiota. Selected animal studies were also considered if showing mechanistic observations.

RESULTS: FC is associated with alteration in microbiome composition. Motility and fecal consistency are affected with different efficacy by the type of fiber, prebiotic or probiotic strain used in patients.

CONCLUSIONS: Selected bacterial strains, mainly belonging to the Bifidobacterium genus, and some poorly or non-fermented natural fibers, such as Psyllium, may significantly improve FC and may represent the basis for an effective supplementation.
