(Web Desk) — Recent research indicates that gut bacteria and viruses could play a significant role in elevating the risk of type 2 diabetes among individuals worldwide.

According to findings from the Microbiome and Cardiometabolic Disease Consortium (MicroCardio), analyzed data from over 8,000 diverse participants globally highlights the potential influence of the gut microbiome on this chronic condition.

Dr. Daniel (Dong) Wang, co-corresponding author of the study and Assistant Professor of Medicine at Brigham, emphasizes that while previous research hinted at this connection, the new study provides robust evidence linking specific microbial species and their functions within the gut to type 2 diabetes. Particularly noteworthy is the identification of Prevotella copri, a gut microbe known for its production of branched-chain amino acids (BCAAs), found in higher quantities in individuals with type 2 diabetes.

Additionally, the study suggests that bacteriophages, viruses targeting bacterial cells, may also contribute to altering gut microbiota composition, thereby potentially increasing diabetes risk. This research underscores the complexity of the microbiome’s role in metabolic health and highlights avenues for further investigation into preventive strategies and treatments for type 2 diabetes.
