Why Do People Get Kidney Stones in the Summer?

It’s normal to feel anxiety, worry, and grief any time you’re diagnosed with a medical condition – and that’s certainly true if you test positive for COVID-19, or are presumed to be positive. If your symptoms aren’t severe and you can recover at home, this will involve home isolation until it’s safe for you to be near others without potentially spreading the infection.

The prevalence of kidney stones, a painful urological disorder characterized by the formation of hard mineral deposits in the kidneys, notably increases during the summer months.

Understanding Kidney Stones

Kidney stones form when certain substances, like calcium, oxalate, and uric acid, become concentrated in the urine to form crystals. Over time, these crystals can build up to form stones, varying in size, and can cause significant pain and other symptoms when passing through the urinary tract.

The Summer Connection: Dehydration and Diet

  1. Dehydration: A Key Factor
    • Data Insight: Studies have shown a clear correlation between warmer temperatures and kidney stone prevalence. For instance, a research study demonstrated a significant increase in kidney stone cases during high-temperature periods.
    • Reasoning: High temperatures and increased outdoor activities during summer lead to more sweating and less fluid retention, potentially leading to dehydration. Dehydration is a crucial factor as it increases the concentration of minerals and salts in the urine, creating an environment more conducive to stone formation.
  2. Dietary Changes:
    • Summer Diets: People tend to consume more salt and protein-rich foods during summer activities like barbecues, which can contribute to the formation of stones.
    • Research Findings: Charts and data from dietary studies highlight an increase in the consumption of foods high in oxalates and calcium during summer months, directly impacting kidney stone risk.

Preventive Measures

  • Hydration: Maintaining adequate hydration is crucial, especially in hot weather. It’s recommended to increase water intake during summer to prevent urine from becoming too concentrated.
  • Balanced Diet: Moderating the intake of oxalate-rich foods, reducing salt, and balancing protein consumption can be beneficial.
  • Lifestyle Adjustments: Avoid excessive sun exposure and ensure adequate fluid replacement after physical activities.

Medical Perspectives and Treatment

  • Clinical Advice: Medical professionals often see an uptick in kidney stone cases during summer and advise patients to be vigilant about hydration and diet.
  • Treatment Trends: Data from hospitals and clinics often show a seasonal spike in treatments for kidney stones, including lithotripsy, during the summer months.


The summer season, with its high temperatures and specific lifestyle patterns, plays a significant role in the increased incidence of kidney stones. Understanding this connection is crucial for both prevention and effective management of this condition. By focusing on adequate hydration, dietary adjustments, and being aware of the symptoms, individuals can reduce their risk of developing kidney stones during these warmer months. Continued research and public awareness are essential for addressing this seasonal health challenge effectively.
