According to a recent Swedish study in the journal Nature, people living with type 2 diabetes also harbor a population of altered gut microbia. These findings may be a critical piece in identifying those at risk for type 2 diabetes.
Interestingly, women without type 2 diabetes hold greater numbers of bacteria in their gut that produce a fatty acid called butyrate, which has known health benefits.
According to Zeenews, "our bodies thus contain a vast number of bacterial genes in addition to the genes in our own cells, and are collectively known as the metagenome." By analyzing the metagenome, researchers are able to distinguish between subjects with and without type 2 diabetes.
What does this mean? That doctors will have an accurate tool for predicting type 2 diabetes — while they can take action to prevent it. Metagenome analysis apparently functions with a higher predictive disease correlation than the heavily relied upon body mass index (BMI) or waist-hip ratio.
The next step is discovering if gut microtia creates an environment in which type 2 diabetes thrives. Clearer connections are emerging between microbes and the human condition — namely diabetes, obesity, cardiovascular disease and metabolic syndrome.
