A study shows that the composition of gut microbiota in early pregnancy can predict the later development of gestational diabetes mellitus (GDM). Analyzed fecal samples from 61 pregnant women in Zhangzhou, China, revealed distinct microbiota profiles weeks before clinical GDM onset. Increased levels of harmful bacteria, such as Escherichia-Shigella, correlated with GDM, while beneficial genera were diminished. The findings suggest that early microbial screening may allow for earlier GDM diagnosis and timely interventions, although limitations exist in sample size and geographic scope.
