During the month of Ramzan, abstaining from food and water is a spiritual ritual, but prolonged fasting, especially in hot weather, can strain urinary health. Experts warn that kidney stones, urinary tract infections (UTIs), and prostate issues often spike if hydration isn’t handled carefully.

For those observing Ramzan, dawn-to-sunset, fasting is a sacred practice. But while the soul is nourished, the body, especially the urinary system, can bear the brunt of long hours without water.

Many don’t realise that dehydration doesn’t just make you thirsty, says Dr Mangesh Patil, urologist at Saifee Hospital, Mumbai, “it affects your kidneys, bladder, and prostate in ways that can escalate if ignored.”

During fasting, the kidneys work overtime to concentrate urine, often leading to mineral buildup. Meanwhile, reduced urination gives bacteria a window to multiply, and men with prostate enlargement may notice their urinary symptoms worsening. Awareness and careful hydration are the keys to staying safe.

Experts stress that small, consistent fluid intake between Iftar and Suhoor, alongside water-rich foods and limited salt, can prevent most fasting-related urinary problems. Dr Patil informs, “Smart hydration is not just about drinking water, it’s also about timing and balance. One careless evening can trigger discomfort or even a medical emergency.”

Kidney stones

When water intake drops for 12–15 hours, urine becomes highly concentrated. Minerals like calcium, oxalate, and uric acid can crystallise, bonding into stones.

Triggers

• High salt intake at Suhoor
• Excess animal protein
• Very low fluid intake between Iftar and Suhoor

Dr Patil warns, “Those with previous kidney stones must be extra cautious. Even a single day of poor hydration can trigger severe pain.”

Urinatry tract infection (UTI)

Fasting slows urine flow, leaving bacteria lingering in the urinary tract longer. Highly concentrated urine also irritates the bladder lining.

Symptoms to watch

• Burning sensation
• False urgency
• Lower abdominal discomfort
• Women and recurrent UTI sufferers should pay special attention. “Skipping fluids is like giving bacteria a free pass,” says Dr Patil.

Prostate health

Men with enlarged prostates sometimes restrict water to avoid night-time trips to the loo. Ironically, this backfires. Concentrated urine irritates the bladder neck and prostate.

Signs you may notice

• Frequent urination
• Nocturia
• Weak stream
• Urgency

“Drinking less can worsen the very issues you hope to prevent,” Dr Patil remarks.

Dr Patil’s hydration strategy for Ramzan

Practice interval hydration

Sip 200–250 ml every hour between Iftar and bedtime, plus fluids at Suhoor.
