Gut bacteria linked to recurrent pregnancy loss

For couples struggling with unexplained recurrent pregnancy loss, the gut may hold clues. A new review of the research finds that their gut microbiome is often in a state of dysbiosis, or imbalance. This means key helpful bacteria are lower, while potentially harmful ones are higher. The review points to a pattern of reduced levels of Bacteroidetes, Lactobacillus, and Bifidobacterium, and an increase in Proteobacteria and Escherichia-Shigella. It also notes a decrease in the overall diversity of the gut community. The review suggests a possible two-way street between gut health and pregnancy loss, but it is based on existing studies that have inconsistent findings. The research does not prove cause and effect, and it does not report on any treatments or safety outcomes. This points to a potential future focus on gut health for couples dealing with this heartbreaking challenge.
