Link Between Pollution And Diabetes

Web Desk(July 09, 2018): A new study, designed to estimate the harmful effects of poor air quality, revealed a significant correlation between diabetes and pollution levels. The conclusion, the author’s hope, will help to shape future guidelines.

Air pollution and diabetes are responsible for millions of death globally.

According to the World Health Organization (WHO), air pollution can lead to lung cancer, respiratory infection, stroke, and even heart disease. Air pollution is a global issue, but low-income cities are the most affected.

The air quality database — which was updated in 2018 — shows that more than 80 percent of people who live in urban areas breathe air that does not meet the WHO guidelines. Diabetes is a chronic disease that occurs when the body’s ability to produce the hormone insulin is reduced, leading to high blood sugar levels. Diabetes can be treated, but complications can lead to kidney failure, heart disease, and stroke.

Data from the WHO show that in 2014, 8.5 percent of adults developed diabetes and that in 2015, this health condition resulted in 1.6 million deaths.

How does pollution lead to diabetes?

The exact mechanism behind the relationship between air pollution and diabetes has not yet been proven. However, scientists know that some pollutants — once they have been breathed in — can enter the bloodstream and interact with tissues and organs. These interactions ultimately disrupt the body, and, among other things, may alter insulin sensitivity and production.

It is important to note that the risk of pollution-related diabetes is higher in lower-income countries that lack clean air policies, such as India, China, and Indonesia, while more wealthy countries, such as Canada, Australia, and New Zealand, have a lower risk. The study findings suggest that the risk of diabetes rises dramatically between the lowest possible exposure levels and the EPA guidelines for air quality standards.

In other words, even at levels that are officially deemed “safe,” the risk is still significant. In October 2017, the Lancet Commission on pollution and health published a report highlighting the harmful effects of pollution.

This new study, which aimed to find new evidence, uncovered proof that pollution can have an even greater impact on health, possibly leading to the development of diabetes.
