With sudden shifts in weather cool mornings giving way to scorching afternoons doctors across the city are witnessing a rise in urinary tract infection (UTI) cases. The primary culprit is Dehydration.

Doctors are seeing around 50 cases a week and 20% increase over recent weeks. Explaining the cause behind the spike, she said: "UTIs can be triggered by dehydration, holding urine for long periods or untreated previous infections. They also experience hot flashes because of sudden change in climate, which worsens their condition."

She highlighted that while such infections can occur to anyone, women and children are highly susceptible. "The most common treatment for UTIs is drinking plenty of water or pain relievers," she added.

But what is the link between dehydration and UTI
"Dehydration happens when the body loses more water than it takes in, upsetting its natural balance. One major factor influencing dehydration is extreme heat. When temperatures soar, we lose fluids rapidly through sweat. If we don't replenish this lost water, urine becomes concentrated and sits in the bladder longer, creating an ideal environment for bacterial growth and increasing UTI risk. Doctors say that the hospital sees a minimum of three cases a day.

She emphasized how temperature fluctuations worsen symptoms for those already dealing with UTI. "A key impact is increased urinary frequency, especially at night. Dehydration caused by abrupt heat spikes leads to concentrated urine, which irritates the bladder and intensifies discomfort. These rapid shifts highlight the need for extra hydration, proper hygiene and preventive care," she added.
