Air pollution has become a major concern of our time. With the increasing number of industries and automobiles, the air quality has worsened, leading to numerous health complications for people.
One such health implication is diabetes, which is a chronic metabolic disorder affecting millions of people worldwide. According to studies, air pollution can lead to type 2 diabetes mellitus and also exacerbate the condition in patients who are already suffering from diabetes.
What is diabetes?
Diabetes mellitus is a disorder in which blood sugar levels increase beyond the normal range. The disease is caused due to the inability of the body to produce insulin or the inability of the body cells to utilize insulin effectively.
There are two primary types of diabetes: type 1 and type 2. Type 1 diabetes occurs when the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas.
Type 2 diabetes, on the other hand, occurs when the body’s cells become resistant to insulin or the pancreas produces less insulin.
How air pollution affects diabetes?
Air pollution contains various harmful substances such as particulate matter, nitrogen oxides, and sulfur dioxide.
These pollutants trigger oxidative stress and inflammation in the body, affecting the insulin-producing beta cells and the glucose metabolism. Studies have shown that long-term exposure to these pollutants can lead to development of insulin resistance, metabolic syndrome and type 2 diabetes mellitus.
In addition, people with existing diabetes may experience exacerbation of symptoms due to air pollution.
Particulate matter and diabetes
Particulate matter (PM) refers to tiny airborne particles that can penetrate deep into the lungs and enter the bloodstream. PM2.5, which is a type of fine PM with a diameter of 2.5 micrometers or smaller, is particularly harmful.
PM2.5 can cause lung inflammation, oxidative stress, insulin resistance, and systemic inflammation. Exposure to PM2.5 has been linked to increased risk of diabetes, cardiovascular disease and premature death.
Nitrogen oxides and diabetes
Nitrogen oxides (NOx) are also common air pollutants, mainly emitted by burning fossil fuels. NOx can affect the immune system, cause inflammation, and lead to cardiovascular complications.
Studies have shown that exposure to NOx could lead to insulin resistance and various metabolic disorders. In addition, NOx exposure may result in high blood pressure, which is a risk factor for diabetes.
Sulfur dioxide and diabetes
Sulfur dioxide (SO2) is produced mainly by burning sulfur-containing fossil fuels such as coal and oil. SO2 can cause lung irritation and exacerbate asthma and COPD.
Studies have found that long-term exposure to SO2 can increase the risk of type 2 diabetes mellitus. SO2 can affect glucose metabolism, reduce insulin sensitivity and lead to oxidative stress and inflammation in the body.
Other air pollutants and diabetes
Besides PM, NOx, and SO2, there are various other air pollutants that can pose a threat to people with diabetes. These include ozone, carbon monoxide, volatile organic compounds and heavy metals.
Exposure to these pollutants can lead to increased insulin resistance, inflammation and oxidative stress, which can worsen diabetes symptoms and increase the risk of developing various complications.
Prevention and management of diabetes in polluted areas
The following are some measures that people with diabetes can take to prevent and manage the complications caused by air pollution:.
- Avoid outdoor activities in high pollution areas whenever possible.
- Use air purifiers and wear masks when going out in pollution-prone areas.
- Monitor blood glucose levels regularly and consult a healthcare professional for adjustments in insulin dosages and medication if needed.
- Maintain a healthy lifestyle with regular exercise and balanced diet to improve insulin sensitivity and reduce the risk of complications.
Conclusion
Air pollution is a serious health issue affecting people worldwide. It has been found to be a potential risk factor for diabetes and can worsen the condition in patients who are already suffering from it.
To prevent and manage diabetes in polluted areas, people should take necessary precautions and follow a healthy lifestyle. By being aware of the risks and taking appropriate measures, we can protect ourselves from the harmful effects of air pollution and lead a healthy life.
