Rising air pollution in several cities, including Delhi-NCR, is becoming a threat not only to the lungs and heart but also to kidney health. According to doctors, prolonged exposure to polluted air can affect the kidneys’ ability to clean the blood. Extremely fine particles such as PM 2.5, in particular, can increase inflammation and oxidative stress in the body and damage the kidneys’ fine filters.
According to Dr. Rajendra Prasad Mathur, a nephrology specialist at the Institute of Liver and Biliary Sciences in Delhi, fine pollution particles can affect the body’s blood vessels and kidney function after reaching the lungs. Long-term exposure to them can reduce kidney function and increase the risk of acute kidney injury.
Research also points to the risk
A meta-analysis published in the Environmental Research journal analysed data from more than 30 lakh people. It found a link between every 10 microgram per cubic metre increase in PM 2.5 levels and a decline in the kidneys’ filtering capacity. However, an AQI of 400 cannot be considered a definite threshold for kidney failure. The risk depends on pollution levels, duration of exposure and a person’s health.
What to do for protection
Experts advise avoiding unnecessary outdoor movement when pollution rises. If going outside is necessary, wear a well-fitting N95 mask. If pollution is high inside the home, keep windows closed and, if possible, use an air purifier with a HEPA filter. Stay away from smoking and things that generate smoke indoors.
People already suffering from kidney disease, high blood pressure or diabetes should take special precautions. If symptoms such as swelling in the legs or face, changes in urination and persistent fatigue appear, consult a doctor for an examination.
