Kidney Stone Epidemic: Why South Indians Are at Higher Risk in 2026 (and How to Prevent It)

Kidney stones are becoming increasingly common in South India — affecting both young professionals and older adults alike. The combination of hot weather, local dietary patterns, and changing lifestyles has made South Indians more prone to stone formation. Dr. B. Sourabh Chandra Reddy, leading urologist and andrologist in Hyderabad at Orene Uro and Andro Care, explains the key reasons behind this growing trend and offers expert advice on prevention in 2026.

Why South Indians Are at Higher Risk

Climate, food habits, and hydration patterns play a major role in kidney stone formation. The hotter climate in South India causes more fluid loss through sweat, increasing urine concentration and mineral crystallisation. Many people also skip drinking water during work hours, further worsening dehydration risk.

Dr. B. Sourabh Chandra Reddy explains: “Kidney stones are not just caused by genetics. In our region, low water intake, high salt diets, and excess oxalate-rich foods are the primary triggers.”

Dietary Patterns That Contribute to Kidney Stones

Traditional South Indian meals are rich in rice, lentils, and spices — but modern variations have introduced high-sodium pickles, processed foods, and excessive caffeine intake. Overconsumption of foods like spinach, tomatoes, beetroots, and nuts, which are high in oxalates, can also increase the risk of calcium oxalate stones.

Tip: Balance meals with adequate fibre and calcium intake. Avoid crash diets, overuse of protein supplements, and limit salt to less than 5 grams per day as recommended by the World Health Organization (WHO).

The Role of Hydration and Weather

Dehydration remains the biggest culprit in kidney stone formation. With Hyderabad and other South Indian cities experiencing prolonged summers, maintaining proper hydration throughout the day is essential. Insufficient water intake leads to concentrated urine, making it easier for minerals to crystallise and form stones.

Hydration Tips:

• Drink at least 2.5 to 3 litres of water daily (more if you sweat excessively).
• Include fluids like buttermilk, lemon water, or coconut water for natural electrolytes.
• Monitor urine colour — pale yellow indicates proper hydration.

Modern Lifestyle Triggers in 2026

Prolonged sitting, lack of physical activity, and high-protein diets are now common in urban areas. Many office-goers delay bathroom breaks, causing mineral buildup in the urinary tract. Overuse of calcium and vitamin D supplements without medical guidance can also increase stone risk.

Dr. B. Sourabh Chandra Reddy advises: “Today’s lifestyle makes stone prevention more about daily discipline than medical treatment. Hydration, balanced meals, and timely bathroom habits can drastically cut your risk.”

Latest Preventive Guidelines for South Indians

• Limit salt, sugar, and animal protein in daily diet.
• Stay active – regular walking helps kidney function and urinary flow.
• Eat calcium-rich foods (like curd and milk) instead of skipping calcium altogether.
• Get annual kidney health check-ups if you have a family history of stones.
• Consult a urologist immediately for pain, blood in urine, or frequent infections.

At Orene Uro and Andro Care, Hyderabad, Dr. B. Sourabh Chandra Reddy uses advanced diagnostic tools like ultrasound and metabolic evaluation to identify the exact cause of stones. His preventive programs include diet planning, lifestyle counselling, and minimally invasive treatments to ensure long-term kidney health.
