The mechanisms of action of some common medications remain unknown but, in some cases, may involve the microorganisms within us. A new study by Wu et al. (2017) provides evidence that the type 2 diabetes drug metformin alters the gut microbiota, which in turn may mediate some of the drug's effects.
