I Drink Water, But I Still Get Kidney Stones—Why?
I Drink Water, But I Still Get Kidney Stones—Why?
“I drink 2–3 liters of water a day, but I’ve developed another kidney stone.” I hear this statement quite often in my clinic. Water intake is one of the most important steps in preventing kidney stone formation, but it is not always sufficient on its own. Kidney stones are a complex condition influenced by a combination of factors, including genetic predisposition, dietary habits, metabolic disorders, and the chemical composition of urine.
AsProf. Dr. Volkan İzol, I don’t just tell my patients with recurrent kidney stones to “drink more water.” I investigate why the stones keep forming and develop a personalized preventive treatment plan for each patient.
Why Do I Get Kidney Stones Even Though I Drink Water?
Even if you drink enough water, one of the following reasons may lead to the formation of kidney stones:
- Genetic predisposition
- Excessive salt intake
- Excessive consumption of animal protein
- High levels of calcium, oxalate, or uric acid in the urine
- Low citrate level
- Obesity and Metabolic Syndrome
- Hormonal disorders such as hyperparathyroidism
- Recurrent urinary tract infections
For this reason, kidney stones cannot be explained by water intake alone.
How Do You Know If You're Drinking Enough Water?
It's not just the amount of water you drink that matters—the amount of urine you produceis important, too.
The goalis to produceabout2–2.5 liters of urineper day.If your urine is light yellow or nearly colorless, this is usually a sign that you are getting enough fluids.
In hot weather, people who engage in intense exercise or sweat profusely may need to drink more fluids.
Do Eating Habits Affect Kidney Stone Formation?
Yes. Diet plays an important role in the formation of kidney stones.
Habits that may increase the risk of kidney stones:
- Eating too much salt
- Frequent consumption of processed foods
- Excessive consumption of red meat
- Excessive consumption of sugary drinks
- Uncontrolled consumption of foods high in oxalates (such as spinach, beets, nuts, and chocolate)
Conversely, adequate calcium intake does not increase the risk of stones in most patients; in fact, it may even have a protective effect against certain types of stones. For this reason, it is not advisable to completely eliminate milk and dairy products unnecessarily.
Why Are Stone Analysis and Metabolic Evaluation Important?
The most effective way to understand the composition of a stone is to analyze it—if possible, a stone that has been dislodged or extracted.
In patients with recurrent kidney stones, additionally;
- 24-hour urine analysis
- Blood tests
- Urinalysis
- Necessary metabolic tests
This can help identify the risk factors that lead to stone formation.
Treatment varies for each patient with kidney stones. Calcium stones, uric acid stones, and cystine stones each require different approaches.
What Can Be Done to Prevent Kidney Stones?
To reduce the risk of kidney stones, the following recommendations should be followed:
- Drink water regularly throughout the day.
- Reduce your salt intake.
- Eat a balanced amount of protein.
- Maintain your ideal weight.
- Exercise regularly.
- Follow the personalized nutrition recommendations based on your stone analysis.
- Be sure to keep up with the checkups your doctor has recommended.
Conclusion
If you say, “I drink water, but I still get kidney stones,” the underlying cause may not be just insufficient fluid intake, but could also be due to various metabolic or dietary factors. AsProf. Dr. Volkan İzol, I conduct a detailed investigation into the cause of kidney stones in my patients with recurrent kidney stones and develop a personalized prevention program for each individual. Through proper evaluation and regular follow-up, the risk of kidney stones recurring can be significantly reduced.
