Your kidneys primarily filter waste products and excess fluids from the blood, which are excreted as urine. In addition to waste elimination, the kidneys help regulate several important bodily functions. They maintain the right balance of fluids in the body, which is vital for proper hydration and organ function. Kidneys also regulate levels of electrolytes like sodium, potassium, and calcium, which are essential for muscle function, nerve transmission, and other critical processes. Additionally, they are responsible for blood pressure regulation and red blood cell production. However, a few daily habits can negatively affect your kidney function. While dehydration, smoking and high sodium intake are well-known causes of kidney issues, overuse of painkillers can also pose a significant risk.
How painkillers affect kidney healthPainkillers are easily available over the counter. From handbags to side tables, you will find them everywhere for easy access. This often leads to overuse. While painkillers, especially non-steroidal anti-inflammatory drugs (NSAIDs), can provide relief from pain and inflammation, their overuse can severely impact kidney health.
As a urologist with over 40 years of experience in treating kidney ailments in Indian cities like Delhi and Lucknow, I’ve witnessed many patients blindsided by a silent epidemic- overuse of painkillers ravaging kidneys,” says Dr. Anant Kumar, Chairman, Urology, Renal Transplant and Robotics, Uro-Oncology, Max Super Speciality Hospital, Saket.”NSAIDs or pain killers constrict kidney blood vessels, slashing filtration and causing acute kidney injury (AKI). Nephrotoxicity from NSAIDs affects 1-5% of users, but widespread use means massive impact. Studies link long-term intake to heightened chronic kidney disease risk, especially in diabetics or hypertensives. In Indian hospitals, nephrotoxins like NSAIDs may contribute to almost 40% of AKI cases. This kidney scarring from chronic abuse has even hit young adults-like a recent 24-year-old patient of mine on high-dose diclofenac for three years, ending in end-stage renal disease,” Dr. Kumar adds.
