It has long been known that sugar, obesity, and physical inactivity can lead to diabetes. In a new study, researchers have now found another cause that has gone unnoticed: the bad air.
6.7 million – about as many people suffer from diabetes in Germany. An unhealthy lifestyle is the cause of the disease – at least for type II diabetes. But even a bad air is a trigger for metabolic disease, researchers at the Washington School of Medicine in St. Louis US now in a new study.
Diabetes – These Types Exist
There are two main types of diabetes that differ fundamentally in their triggers. Type I diabetes usually occurs in children or adolescents. The cause is usually hereditary damage to the pancreas, which disrupts the production of insulin.
Type II diabetes, much more common, is due to poor nutrition associated with poor physical exercise and metabolic disease caused by obesity. A homemade problem. The disease usually develops in adulthood.
This type of diabetes was studied by the research team in the new study published in the journal "The Lancet Planetary Health".
Particulate pollution increases the risk of diabetes
Researchers collected data from 1.7 million American veterans for the study. At the beginning of the study, none of the participants in the study had diabetes, so scientists were able to observe the number of new cases over the next eight years.
Outcome: People living in high particle regions were more likely to develop type II diabetes. Even when the amount of particles remains below the World Health Organization (WHO) limit values, diabetes is increasing.
The results are based on measurements of PM2.5 concentrations (microparticles with a diameter of 2.5 microns) in the respiratory air. Each increase in particle concentration of 10 micrometers per cubic meter of air was associated with a 15 percent increase in the risk of diabetes, according to the study.
Disturbance of insulin production by exhaust gases?
Apparently, the cause of type II diabetes can also come from the escape of cars. The smaller particles enter our bloodstream via the airways – causing the most diverse damage in the body.
"It can be assumed that pollution reduces the production of insulin and causes inflammation that prevents the conversion of glucose into energy. According to the authors of the study
The impact of the disruption of insulin production caused by this is frightening, according to the researchers: "The pollution in 2016 contributed to 3.2 million new cases of diabetes around the world about 14% of new cases match. "
