Kidney stones are tiny mineral build-ups may be small in size, but they can lead to excruciating pain when traveling through the urinary tract. Though small in size, they can have a big impact on your daily life, causing discomfort, urinary issues, and even complications if left untreated.
Thankfully, kidney stone prevention is possible through conscious lifestyle and dietary changes. Whether you’ve had stones before or are simply looking to avoid them, adopting these simple yet effective tips can go a long way in protecting your renal health.
In this article, we will share 7 practical tips on how to prevent kidney stones naturally, the types of stones to be aware of—particularly oxalate stones—and lifestyle tweaks that make a difference.
Understanding kidney stones
Kidney stones form when the concentration of certain substances like calcium, oxalate, or uric acid in the urine becomes too high, leading to crystallization. These stones originate when urine contains too much calcium, oxalate, or uric acid, causing crystals to form and gradually grow into larger masses.
Common types include:
- Calcium Oxalate Stones: The most prevalent type, often formed when oxalate levels are high.
- Uric Acid Stones: Common in individuals who consume diets high in animal protein.
- Struvite Stones: Typically associated with recurrent urinary tract infections.
- Cystine Stones: Caused by a genetic disorder, less common but recurrent.
Foods rich in oxalate—such as spinach, beets, and certain nuts—can raise the risk of stone formation when consumed in excess without adequate water or calcium.
1. Stay hydrated—The first line of defense
The most crucial tip for kidney stone prevention is increasing your fluid intake. Water dilutes the concentration of minerals in your urine, making it harder for stones to form.
What to Do:
- Aim for at least 2.5 to 3 liters of water daily.
- Include citrus drinks like lemon water to boost citrate levels, which prevent stone formation.
- Limit intake of sugary sodas and energy beverages, as they are known to raise the chances of kidney stone formation.
2. Cut Down on Sodium
Consuming too much salt can increase the amount of calcium excreted in urine, which may lead to calcium-based kidney stones.
What to Do:
- Limit salt to less than 2,300 mg per day (or 1,500 mg if you’ve had stones before).
- Steer clear of overly salty packaged foods, canned goods, and processed snacks.
- Choose fresh meals and use herbs or lemon for seasoning.
3. Limit Oxalate-Rich Foods—But Don’t Eliminate Them Entirely
Oxalate stones are formed when oxalate combines with calcium in the urine. Reducing your intake of high-oxalate foods can be helpful, especially for those prone to kidney stones.
What to Do:
- Cut back moderately on foods like spinach, rhubarb, beets, almonds, and dark chocolate.
- Pair oxalate-rich foods with calcium-rich ones (like yogurt or milk) to bind oxalate in the gut instead of the kidneys.
- Don’t cut them out entirely—oxalates are also found in healthy foods. Balance is key.
4. Increase Calcium Intake—But From the Right Sources
Reducing dietary calcium can backfire by increasing oxalate absorption and raising stone risk. The key is getting calcium from food rather than supplements.
What to Do:
- Consume dairy products, leafy greens, and fortified foods for daily calcium needs.
- Avoid calcium supplements unless prescribed, as they can raise stone risk when not paired with food.
- Calcium helps bind oxalates in the intestine, preventing their absorption.
5. Eat Less Animal Protein
Red meat, eggs, and seafood are rich in purines, which can increase uric acid levels and promote stone formation.
What to Do:
- Limit red meat to a few times a week.
- Opt for plant-based proteins like lentils, beans, and tofu.
- Add more vegetables and whole grains to your meals for better balance and long-term renal support.
A balanced, plant-forward diet is beneficial not only for kidney stone prevention but also supports liver health and overall metabolic function.
6. Maintain a Healthy Weight
Being overweight increases your risk for both kidney stones and metabolic disorders like diabetes and fatty liver.
What to Do:
- Getting at least 30 minutes of moderate exercise each day—such as brisk walking or yoga—can help lower your risk of stones.
- Avoid crash diets, especially high-protein ones, which can worsen the risk of stone formation.
- Focus on gradual, sustainable weight loss with the help of a nutritionist or physician.
Studies from Mayo Clinic suggest that obesity, insulin resistance, and poor metabolic health are all associated with higher incidence of kidney stones and liver diseases.

7. Monitor and Manage Medical Conditions
Health conditions like hyperparathyroidism, frequent urinary tract infections, or liver disease can raise your likelihood of developing kidney stones.
What to Do:
- Schedule regular health screenings, particularly if you have a history of stones.
- Take medications as prescribed to manage uric acid, blood pressure, or bile flow if needed.
- Talk to your doctor about any family history or underlying health concerns that may affect kidney function.
If you have had oxalate stones or uric acid stones previously, a personalized dietary plan and periodic kidney function tests can help in long-term management.
