Why your summer weight loss diet could be triggering kidney stones

Medical experts have warned of a predictable surge in kidney stone cases as the summer season commences. Dr Chandan M N, a consultant urologist at Apollo Hospitals, Bengaluru, noted that while dehydration is a well-known factor, "modern lifestyles are quietly adding fuel to the problem."

The seasonal spike is increasingly driven by a combination of extreme fitness regimes, excessive supplement use, and misunderstood environmental factors that alter internal body chemistry.

High-protein weight loss diets, often pursued to achieve a 'summer body', are primary contributors to renal distress. “Excess animal protein increases calcium and uric acid in urine while lowering citrate, a natural inhibitor of stone formation,” Dr Chandan reasoned.

Furthermore, the consumption of iced teas and colas to combat heat often introduces high oxalate and sugar levels, further elevating the risk.

Top 3 reasons for kidney stone cases in summer

• Extreme weight loss diets: High animal protein and oxalates from 'healthy' swaps like spinach and nuts can trigger stone formation.
• Overuse of supplements: Excessive Vitamin C can convert into oxalate. “In the body, excess vitamin C can convert into oxalate, a key component of the most common kidney stones,” Dr Chandan added.
• Sweating and air conditioning: Heavy sweating alters mineral balance, yet individuals in air-conditioned spaces often fail to increase water intake because they "sweat less noticeably indoors."

Warning signs

• Burning sensation during urination
• Persistent flank pain
• Blood in urine
• Repeated urinary infections

Prevention remains straightforward, focusing on balanced meals, moderate salt intake, and natural citrate sources like citrus fruits to inhibit crystal growth.
