Abstract
Benefits of probiotic supplementation for symptoms associated with gestational diabetes are limited. The purpose of this review was to investigate the effects of probiotic supplementation on glycemic control in women with gestational diabetes mellitus (GDM). A systematic search for randomized controlled trials (RCTs) reporting probiotic supplementation in GDM patients (2000 through 2019) yielded 65 articles. Eight RCTs met the criteria for inclusion. Probiotics decreased fasting plasma glucose and serum insulin levels. Significant effects were found on insulin resistance, insulin sensitivity, and lipid profiles. Probiotic supplementation may improve glycemic control, insulin resistance, and lipid profiles; more research is needed.
