Experts warn of rising kidney disease cases linked to dehydration, painkiller misuse

Medical experts have raised concerns over a growing incidence of Chronic Kidney Disease, attributing the trend to chronic dehydration, misuse of over-the-counter painkillers, and poorly managed high blood pressure.

The warning was issued during a recent medical briefing in Lagos, where healthcare professionals described the condition as a “silent threat” that often goes undetected until significant kidney damage has occurred.

According to the experts, Hypertension remains one of the leading causes of kidney failure. Persistent high blood pressure damages the kidneys’ blood vessels, impairing their ability to filter waste effectively.

They further identified chronic dehydration as a major contributing factor, particularly in hot climates and among individuals with demanding work routines. Inadequate fluid intake, they said, increases the risk of kidney stones and places additional strain on the kidneys.

Another major concern highlighted is the increasing cases of Analgesic Nephropathy, a condition caused by prolonged use of certain painkillers. Common non-steroidal anti-inflammatory drugs (NSAIDs) such as Ibuprofen and Diclofenac were cited as frequently misused medications that can reduce blood flow to the kidneys when taken excessively, potentially leading to organ damage.

Health professionals advised the public to adopt preventive measures, including maintaining adequate hydration levels estimated at 2.5 to 3 litres of water daily especially for those in physically demanding or outdoor occupations.

They also cautioned against self-medication, urging individuals to avoid using painkillers for more than a few days without medical supervision. Regular health screenings, particularly for people over 30 or those with a family history of hypertension, were also recommended.

Experts added that lifestyle changes such as reducing salt intake and limiting processed foods can help lower the risk of kidney-related complications.

They concluded that while kidney disease can have severe consequences, early detection and responsible medication use remain critical in preventing its progression.
