Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit to the host. Specific probiotics or probiotic foods can be used to reduce the risk of diseases associated with aberrant gut microbiota composition. The incidence of gestational diabetes mellitus (GDM) has increased annually with the proportion of overweight and obese people. Overweight or obese pregnant women are at high risk of GDM and have obvious changes in gut microbiota compared with normal-weight pregnant women. Specific probiotics or probiotic foods may alter gut microbiota in overweight or obese pregnant women and inhibit the expression of inflammatory factors, consequently resulting in weight loss and reduced insulin resistance. This review discusses the mechanism of probiotics on GDM, as well as the dose, method and duration of probiotics use, and summarizes current evidence on probiotics in improving glucose metabolism and other maternal and infant outcomes in overweight/obese pregnant women.
Core Tip: The occurrence and progression of gestational diabetes mellitus (GDM) are associated with intestinal microbiota disorder. Probiotics modulate the gut microbiota, which can decrease lipopolysaccharide-containing microbiota in the gut and plasma lipopolysaccharides, and inhibit expression of inflammatory factors, thereby reducing insulin resistance, modulating glucose metabolism, and preventing GDM, especially in high-risk groups such as overweight/obese pregnant women. This review provides up-to-date evidence on the effects of probiotics in preventing GDM and improving glucose metabolism and other maternal and infant outcomes in overweight/obese pregnant women, and discusses the mechanism of probiotics on GDM, and the dose, method, and duration of probiotics use.
