Taking control of your health amidst rising pollution levels is not just a choice—it’s a necessity
Preventive health checks are vital for identifying early signs of stress on your kidneys
As air pollution continues to reach alarming levels in Delhi, its health implications are becoming increasingly apparent. While the focus often falls on respiratory and cardiovascular health, experts are now highlighting the serious risks air pollution poses to kidney health. Here’s what the specialists have to say and how you can mitigate the impact.
The Link Between Air Quality and Kidney Health
Increased Risk of Kidney Disease
Dr. Saurabh Pokriyal, Chief Medical Director, VitusCare, warns that prolonged exposure to pollutants like nitrogen dioxide (NOâ‚‚) and sulfur dioxide (SOâ‚‚) can lead to inflammation and oxidative stress. These conditions harm multiple organs, including the kidneys, and can accelerate the decline of kidney function. Individuals with pre-existing conditions such as hypertension, diabetes, or obesity are particularly vulnerable, as these are common risk factors for kidney disease.
Aggravating Pre-Existing Conditions
“For those already suffering from chronic kidney disease (CKD), high AQI levels can exacerbate their condition,” Dr. Pokriyal explains. Pollutants can elevate blood pressure and trigger inflammatory responses, worsening renal impairment.
Blood Pressure and Cardio-Renal Risks
“Hypertension is a critical risk factor for kidney disease,” Dr. Pokriyal adds. Poor air quality is linked to increased blood pressure and cardiovascular risks, which indirectly impact kidney health.
Oxidative Stress and Heavy Metal Deposition
Dr. Geetanjali Gupta, Director of Technical Operations and Quality Assurance, Redcliffe Labs, notes that air pollution can lead to oxidative stress, causing kidney inflammation and even contributing to the formation of kidney stones. Furthermore, pollutants such as lead and arsenic can accumulate in the bloodstream, leading to toxicity that directly affects kidney function.
Immune System and Toxin Build-Up
Inhaling polluted air weakens the immune system, increasing the risk of systemic infections that can damage the kidneys over time. Additionally, toxin build-up from air pollution can overwhelm kidney function, says Dr. Pokriyal.
Symptoms of Kidney Impact from Air Pollution
According to Dr. Gupta, symptoms like muscle cramps, loss of appetite, dry and itchy skin, back pain, puffy eyes, shortness of breath, and issues with urination can indicate pollution-related kidney stress. “If you’re experiencing these signs, it’s critical to seek medical attention,” she advises.
Protective Measures for Kidney Health
Limit Outdoor Exposure
Both experts emphasize minimizing outdoor activities on days with high AQI. “If you must go outside, wear high-quality N95 masks,” Dr. Pokriyal suggests.
Improve Indoor Air Quality
“Control what you can inside your home,” Dr. Gupta advises. Use air purifiers, keep windows closed, and incorporate indoor plants to improve air quality.
Adopt a Kidney-Friendly Diet
Dr. Pokriyal recommends a diet rich in antioxidants, low in sodium, and high in fruits and vegetables to combat the oxidative stress caused by pollutants. Dr. Gupta adds, “Include immunity-boosting foods like citrus fruits, turmeric, garlic, and nuts to strengthen your body’s defenses.”
Stay Hydrated
Regular hydration helps flush toxins from the body, protecting kidney function, advises Dr. Pokriyal.
Avoid Smoking and Unnecessary Medications
“Smoking and certain medications can place additional strain on your kidneys,” Dr. Gupta warns. Avoid these to minimize damage.
Regular Health Monitoring
“Preventive health checks are vital for identifying early signs of stress on your kidneys,” Dr. Gupta emphasizes. Monitoring your immunity and kidney function can help you prepare for environmental challenges.
The Bigger Picture
Dr. Gupta highlights that Delhi’s AQI often exceeds 500, a hazardous level. While external factors like outdoor air quality are difficult to control, proactive measures within your home and lifestyle can significantly reduce the health risks posed by pollution. By staying informed and taking preventive actions, you can safeguard your kidney health against the invisible threat of air pollution.
Taking control of your health amidst rising pollution levels is not just a choice—it’s a necessity. With expert advice from Dr. Saurabh Pokriyal and Dr. Geetanjali Gupta, you now have the tools to protect your kidneys and overall well-being, even in challenging environmental conditions.
