Medical experts have sounded the alarm as Karachi witnesses a sharp rise in kidney infection cases, attributed to severe heat and dehydration, Express News reported on Monday.
Hospitals across the city are reporting an increasing number of patients presenting with lower back pain on both sides, painful urination, reduced urine output, blood and pus in urine, and fever—classic symptoms of kidney-related infections.
According to healthcare professionals, the hot and humid weather gripping Karachi has exacerbated the situation. Dehydration, excessive sweating, and the accumulation of salts and minerals in the body are leading to kidney dysfunction among residents.
Dr Mehreen Urooj, a urologist at Jinnah Hospital Karachi, explained that the typical symptoms of kidney infections include bilateral lower back pain, burning sensation while urinating, decreased urine volume, and the presence of blood or pus in urine, often accompanied by fever and severe discomfort.
“These symptoms point to inflammation or infection of the kidneys, which should not be ignored,” she warned. “During summer, excessive perspiration leads to water loss from the body, while people tend to drink less water. This hampers the kidneys' ability to filter waste, causing salts and minerals to accumulate, which can lead not only to infections but also to the formation of kidney stones.”
She revealed that the number of kidney infection patients at Jinnah Hospital has doubled within a month, with around 150 new cases being reported daily.
Medical professionals are advising the public to consume at least three litres of water per day to ensure the excretion of at least one litre of urine—a key indicator of healthy kidney function and effective detoxification.
Experts stress that timely hydration is critical to preventing kidney complications during the ongoing heatwave.
