Diabetes risk linked to gut microbiome and lifestyle factors

New research highlights the complex interplay between genetics, lifestyle, and biological development in the risk of developing diabetes.

A study published in Nature Metabolism involving 887 children from the TEDDY study suggests that gut microbiome development patterns can help identify those at high genetic risk for type 1 diabetes. Researchers identified three distinct maturation patterns: ‘Early Matured’, ‘Late Matured’, and ‘Early Plateaued’. The ‘Early Plateaued’ pattern, characterized by low microbial diversity and limited divergence from baseline during the first 800 days, was associated with an approximately threefold higher risk of the disease.

Separately, a long-term study of over 332,000 adults in the United Kingdom found that lifestyle choices can significantly outweigh genetic predisposition for type 2 diabetes. While high genetic risk increased the likelihood of developing the condition by approximately 2.6-fold, individuals with the least healthy lifestyles were nearly seven times more likely to develop type 2 diabetes than those with healthy habits. Researchers estimated that over 55% of new type 2 diabetes cases could potentially be prevented through the improvement of modifiable risk factors.
