Kidney stones are becoming increasingly common, especially during hotter months when dehydration risks are higher. These small hard deposits form in the kidneys when minerals such as calcium oxalate or uric acid build up and crystallise in concentrated urine. A widely believed remedy is drinking 10 to 12 glasses of water daily to flush out stones but medical experts say the reality is more nuanced.
According to urology specialists, staying well hydrated plays a crucial role in preventing kidney stones. Adequate water intake helps dilute urine which reduces the chances of minerals sticking together and forming crystals. This makes hydration one of the most effective first steps in lowering the risk of developing stones.
However, when it comes to treating existing kidney stones, water alone is not a guaranteed solution. Doctors clarify that drinking more fluids does not dissolve stones. Instead it may assist in passing very small stones naturally. Typically stones smaller than 5 mm can sometimes pass through the urinary tract with increased urine flow caused by higher fluid intake.
For larger stones the situation is different. Stones that measure more than 6 to 7 mm are unlikely to pass on their own and often require medical treatment. This could include medication to ease symptoms or procedures such as shock wave therapy or minor surgical interventions. Ignoring symptoms like severe pain or infection can lead to complications including kidney damage.
Experts recommend consuming around 10 to 12 glasses of water daily as a general guideline but emphasize that hydration needs can vary depending on climate and activity levels. Monitoring urine colour can be a helpful indicator as pale or clear urine usually signals proper hydration. Ideally the body should produce around two to two and a half litres of urine each day.
In addition to drinking enough water lifestyle changes can further reduce the risk of kidney stones. Reducing salt intake limiting foods high in oxalates such as spinach and nuts and maintaining balanced calcium consumption are all important preventive steps.
Medical professionals highlight that while water is essential for kidney health it should be viewed as part of a broader approach rather than a complete cure. Proper diagnosis and timely treatment remain critical for managing kidney stones effectively.
