Gestational Diabetes Mellitus (GDM) happens to some pregnant women during the second and third trimester of their pregnancy, increasing the risk of developing Type 2 Diabetes Mellitus by 10-fold later in life. Aberrant changes to the gut microbial composition in pregnant gestational diabetic women are found to have a negative effect on the metabolism that may carry on to the postpartum period. On the other hand, probiotics may have a host metabolism modifying effect by reducing inflammation and gut dysbiosis in asymptomatic post-GDM women. This 12-week randomised, double-blinded, controlled, parallel-group clinical trial looked at the effect of probiotic supplementation on inflammatory and metabolic outcomes in asymptomatic post-GDM women. The one hundred and thirty-two participants were randomised to receive either a probiotic formulation containing Lactobacillus and Bifidobacterium stains or a placebo. Participants in the probiotic group showed a significant improvement in fasting blood glucose, HbA1c, total cholesterol, triglycerides and high-sensitivity C-reactive protein compared to the placebo group. In addition, the probiotic supplementation led to an increase in Bifidobacterium adolescentis. Healthcare professionals can use the results of this study to understand the beneficial effects of probiotic supplements in post-GDM women. However, further robust studies are required to evaluate the functions of probiotic supplements in post-GDM women from different backgrounds.
Probiotics are widely used as an adjuvant therapy in various diseases. Nonetheless, it is uncertain how they affect the gut microbiota composition and metabolic and inflammatory outcomes in women who have recently experienced gestational diabetes mellitus (post-GDM). A randomized, double-blind, placebo-controlled clinical trial involving 132 asymptomatic post-GDM women was conducted to close this gap (Clinical Trial Registration: NCT05273073). The intervention (probiotics) group received a cocktail of six probiotic strains from Bifidobacterium and Lactobacillus for 12 weeks, while the placebo group received an identical sachet devoid of living microorganisms. Anthropometric measurements, biochemical analyses, and 16S rRNA gene sequencing results were evaluated pre- and post-intervention. After the 12-week intervention, the probiotics group’s fasting blood glucose level significantly decreased (mean difference −0.20 mmol/L; p = 0.0021). The HbA1c, total cholesterol, triglycerides, and high-sensitivity C-reactive protein levels were significantly different between the two groups (p < 0.05). Sequencing data also demonstrated a large rise in the Bifidobacterium adolescentis following probiotic supplementation. Our findings suggest that multi-strain probiotics are beneficial for improved metabolic and inflammatory outcomes in post-GDM women by modulating gut dysbiosis. This study emphasizes the necessity for a comprehensive strategy for postpartum treatment that includes probiotics to protect post-GDM women from developing glucose intolerance.
