Why do kidney stones increase during the monsoon season?
Kidney stones become more common during the monsoon season because reduced thirst, high humidity, and irregular fluid intake lead to concentrated urine — the primary driver of stone formation. Deccan Hardikar Hospital in Pune, a NABH Pre-Accredited superspeciality centre, urges residents across Western Maharashtra to monitor hydration closely between July and September 2026.
Key fact: During monsoon, people often drink significantly less water because they do not feel thirsty — yet the body continues to lose fluids through sweat and respiration, raising the risk of urinary crystal formation.
This seasonal pattern is well recognised in urology practice. Patients in Pune and surrounding districts of Western Maharashtra frequently present with acute kidney stone episodes in the weeks following the onset of heavy rains — a trend the urology team at Deccan Hardikar Hospital monitors each year.
What is happening with kidney stone cases in Pune this monsoon 2026?
As of July 2026, the southwest monsoon is active across Maharashtra. While rainfall brings relief from summer heat, it creates a deceptive environment for kidney health. The drop in ambient temperature reduces the sensation of thirst, causing many people to cut their daily water intake without realising it.
At the same time, monsoon conditions in Pune introduce additional risk factors:
- Reduced fluid intake — cooler, humid weather suppresses the thirst reflex.
- Dietary shifts — increased consumption of high-sodium street foods, fried snacks, and processed items common during the season elevates urinary oxalate and sodium levels.
- Irregular meal and water schedules — disrupted routines during heavy rain days lead to inconsistent hydration.
- Waterborne infections — gastrointestinal illness causes fluid loss through vomiting or diarrhoea, further concentrating urine.
- Reduced physical activity — staying indoors during rain reduces awareness of fluid needs.
These factors combine to create urine that is more concentrated in calcium, oxalate, and uric acid — the building blocks of the most common kidney stone types.
Why are Pune residents particularly at risk of kidney stones this season?
Pune's geography and urban lifestyle create a specific risk profile during monsoon months. The city's hard water supply contains higher mineral content, which can contribute to calcium-based stone formation when fluid intake drops. Combined with the dietary habits typical of the season, Pune residents face a compounded risk.
Groups at elevated risk in Pune this monsoon include:
- Individuals with a prior history of kidney stones — recurrence risk is higher when hydration lapses.
- Office workers and students who spend long hours indoors and forget to drink water.
- People consuming high-protein diets, which increase urinary uric acid.
- Those with diabetes or metabolic syndrome, which predisposes to uric acid stones.
- Elderly individuals, who have a naturally diminished thirst sensation.
Tip: Check your urine colour daily. Pale yellow indicates adequate hydration. Dark yellow or amber urine is a warning sign that you need to drink more fluids immediately.
Deccan Hardikar Hospital in Pune, located at Shivajinagar, serves as a referral centre for urology and nephrology cases across Western Maharashtra, making it well-positioned to manage both acute stone episodes and long-term prevention.
How does dehydration cause kidney stones, and can weather affect them?
Kidney stones form when the concentration of stone-forming substances — calcium, oxalate, uric acid, or phosphate — in the urine exceeds their solubility. Dehydration is the single most modifiable risk factor because it directly reduces urine volume, allowing these substances to crystallise.
Weather affects kidney stones through its influence on fluid balance:
| Weather Condition | Effect on Kidney Stone Risk |
|---|---|
| High humidity (monsoon) | Suppresses thirst; insensible fluid losses continue through respiration and sweat |
| Cooler temperatures | Reduces perceived need for water; people drink less voluntarily |
| Gastrointestinal illness | Fluid loss from diarrhoea or vomiting rapidly concentrates urine |
| Dietary changes | Seasonal high-sodium, high-oxalate foods increase stone-forming load |
The 7 warning signs of a kidney stone that require prompt medical attention are:
- Severe, cramping pain in the back, side, or lower abdomen (renal colic)
- Pain that radiates to the groin or inner thigh
- Blood in the urine (haematuria) — urine may appear pink, red, or brown
- Nausea and vomiting accompanying the pain
- Frequent or urgent need to urinate
- Burning sensation during urination
- Fever and chills (indicating possible infection — seek emergency care immediately)
Warning: Fever with kidney stone pain may indicate a urinary tract infection or obstructed kidney. This is a medical emergency. Go to the Emergency department at Deccan Hardikar Hospital, Shivajinagar, Pune, or the nearest emergency facility immediately.
What does Deccan Hardikar Hospital recommend to prevent kidney stones this monsoon?
The urology specialists at Deccan Hardikar Hospital in Pune recommend the following evidence-based steps for kidney stone prevention during the 2026 monsoon season:
Hydration
- Aim for at least 2.5 to 3 litres of total fluid intake per day, even when you do not feel thirsty.
- Set hourly reminders on your phone to drink water during work or study hours.
- Include water-rich foods such as cucumber, watermelon, and buttermilk in your diet.
- Avoid relying solely on tea, coffee, or carbonated drinks to meet fluid needs — plain water remains the most effective.
5 foods to avoid if you are prone to kidney stones
- High-oxalate foods — spinach, beets, nuts, and chocolate in large quantities
- Excess salt (sodium) — packaged snacks, pickles, and processed foods common during monsoon
- Animal protein in excess — red meat and organ meats raise urinary uric acid
- Sugary drinks — high-fructose beverages increase uric acid production
- Vitamin C supplements in high doses — the body converts excess ascorbic acid to oxalate
When to seek a urology consultation
- You have had a kidney stone before and notice any new flank or abdominal pain.
- Your urine appears discoloured or you experience burning on urination.
- You develop fever alongside urinary symptoms.
- You have diabetes, gout, or a family history of kidney stones.
