In this context, placental hormones mediate the crosstalk among the placenta, pancreas, and adipose tissue, stimulating endocrine pancreas adaptation and adipose tissue expansion. However, insufficient maternal physiological adaptations, such as dysregulated adipocytokines, adipokines, and oxidative stress in the pancreas, can create an environment conducive to the onset of GDM. Furthermore, gut dysbiosis implies potential mechanisms of gut–host interaction associated with the occurrence of GDM, with short-chain fatty acids possibly serving as crucial targets. Nutritional therapy is recognized as the first-line approach for managing GDM, encompassing dietary guidance and supplementation with micro- and macronutrients as well as bioactive components. Importantly, combined interventions involving multiple nutrients, such as probiotics and prebiotics with vitamins or minerals, may exert stronger beneficial effects on the prevention and treatment of GDM and its complications.
