Due to this same genetic and metabolic potential, the gut microbiome has long been suspected as implicit in human extraintestinal health, including factors of metabolic regulation. Relatively largescale clinical crosssectional observational studies have demonstrated a contributory role for the gut microbiome in host metabolic health.Indeed, a robust correlation was previously identified between increased microbiota diversity, or gene richness, and host metabolic fitness. In addition to contributing to host health and disease, research indicates that the gut microbiome often alters or is altered by certain pharmacological interventions. Indeed, certain drugs are now recognised to be metabolised by gut microbiota members in reactions such as glucuronidation, reduction, oxidation and hydrolysis, can further alter drug kinetics by increasing or decreasing solubility, absorption and excretion. In line with this, the composition of one s gutmicrobiota, which displays degrees of interindividual variation, may explain a degree of the variance in the personalised response observed with certain oral pharmaceutical therapies.
