Could probiotics be the missing ingredient for gestational diabetes?

This study will test whether adding a probiotic supplement to standard diabetes medications (metformin or insulin) improves blood sugar control and reduces inflammation in pregnant women with gestational diabetes. Two hundred women diagnosed between 18-26 weeks of pregnancy will be split into four groups: metformin alone, insulin alone, metformin plus probiotics, or insulin plus probiotics. The goal is to see if the probiotic combination leads to better outcomes for both mother and baby.
