Kidney stones are solid deposits of minerals that form in the kidneys and can cause intense pain when they pass through the urinary tract. It is estimated that around 12 percent of the American population is affected by kidney stones, and individuals who have had a kidney stone in the past are 50 percent more likely to experience another within the next decade.
While it is not possible to completely guarantee the prevention of kidney stones, certain lifestyle changes, dietary modifications, and medications can help reduce the risk. These approaches may include:
1. Adequate hydration: Ensuring sufficient water intake helps dilute urine and prevents the concentration of minerals that contribute to stone formation.
2. Balanced diet: Following a well-rounded diet that includes a variety of nutrient-rich foods and limits excessive intake of certain substances, such as salt, oxalate-rich foods (e.g., spinach, beets), and animal protein, can help reduce the risk of kidney stone formation.
3. Medications: In some cases, medications may be prescribed to help prevent the formation of specific types of kidney stones by modifying urine composition or reducing the levels of certain substances.
It's important to note that individual circumstances and medical history can vary, so it's advisable to consult with a healthcare professional for personalized recommendations and guidance on preventing kidney stones.
How to prevent kidney stones manually
1. Stay hydrated
Proper hydration through increased water intake is highly recommended as the primary measure to prevent kidney stones. When you don't consume enough fluids, your urine output decreases, leading to concentrated urine that is less effective in dissolving urine salts responsible for stone formation.
In addition to water, lemonade and orange juice are beneficial options as they contain citrate, which may help prevent the formation of kidney stones.
Aim to drink approximately eight glasses of fluids per day or enough to produce around two liters of urine. Individuals who engage in regular exercise, experience excessive sweating, or have a history of cystine stones may require even higher fluid intake.
Monitoring the color of your urine can serve as an indicator of hydration status. Ideally, urine should appear clear or pale yellow. If the urine is dark in color, it signifies the need for increased fluid intake.
Remember, it is essential to consult with a healthcare professional for personalized advice and guidance on fluid intake, particularly if you have a history of kidney stones or any underlying health conditions.
2.Eat more calcium rich foods
Contrary to popular belief, avoiding calcium in your diet is not recommended for preventing kidney stones, especially when it comes to the most common type, calcium oxalate stones. In fact, low-calcium diets can potentially increase the risk of kidney stones as well as the risk of developing osteoporosis.
While it's advisable to be cautious with calcium supplements, incorporating calcium-rich foods into your diet is beneficial. Opting for low-fat milk, low-fat cheese, and low-fat yogurt is a good way to obtain calcium from dietary sources.
It's worth noting that taking calcium supplements without a meal may increase the risk of kidney stone formation. To minimize this risk, it is recommended to take calcium supplements with a meal.
As with any dietary considerations, it's important to consult with a healthcare professional or a registered dietitian who can provide personalized guidance based on your specific medical history and needs.
3.Eat less Sodium
Consuming a high-salt diet increases the risk of developing calcium kidney stones. The presence of excessive salt in the urine hinders the reabsorption of calcium from the urine back into the blood. This leads to high levels of calcium in the urine, which can contribute to the formation of kidney stones.
Reducing salt intake is crucial in maintaining lower levels of urine calcium and thereby reducing the risk of kidney stones.
To lower your sodium intake, it is important to carefully read food labels and be mindful of the sodium content in the foods you consume. Processed foods like chips and crackers, canned soups and vegetables, lunch meat, condiments, and foods containing monosodium glutamate, sodium nitrate, or sodium bicarbonate (baking soda) are often high in sodium.
To add flavor to your meals without relying on salt, consider using fresh herbs or salt-free herbal seasoning blends.
As always, consulting with a healthcare professional or a registered dietitian is advisable to receive personalized dietary recommendations and guidance tailored to your specific health needs.
4. Eat fewer oxalate rich food
Restricting the consumption of oxalate-rich foods can potentially aid in the prevention of kidney stones, particularly those composed of oxalate. Oxalate is a naturally occurring compound found in certain foods that can combine with calcium in the urine, leading to the formation of kidney stones. Including calcium-rich foods in your diet alongside oxalate-rich foods may help reduce the likelihood of stone formation.
Here are some examples of foods that are high in oxalates:
- Spinach
- Chocolate
- Sweet potatoes
- Coffee
- Beets
- Peanuts
- Rhubarb
- Soy products
- Wheat bran
When oxalate and calcium are consumed together, they bind in the digestive tract before reaching the kidneys. This binding process makes it more challenging for kidney stones to develop. Therefore, consuming high-oxalate foods along with calcium-rich foods can be beneficial in minimizing the risk of stone formation.
It is important to note that individual dietary recommendations may vary based on specific health conditions and needs. Consulting with a healthcare professional or a registered dietitian is recommended to receive personalized guidance on managing kidney stone risk and incorporating a balanced diet.
5. Eat less animal Protein
Consuming foods that are high in animal protein can contribute to increased acidity in the urine, which in turn may raise the risk of developing uric acid and calcium oxalate kidney stones.
To minimize the risk of these types of kidney stones, it is advisable to limit or avoid the following:
- Beef
- Poultry
- Fish
- Pork
Reducing the intake of animal protein can help maintain a more balanced urine pH and reduce the likelihood of stone formation. It is important to note that dietary recommendations may vary depending on individual circumstances and health conditions. Consulting with a healthcare professional or a registered dietitian is recommended to receive personalized guidance on managing kidney stone risk and adopting a suitable diet plan.
6.Avoid Vitamin C supplements
Excessive intake of vitamin C supplements, specifically in the form of ascorbic acid, has been associated with an increased risk of kidney stone formation, particularly in men.
A study conducted in 2013 found that men who took high doses of vitamin C supplements had twice the risk of developing kidney stones. It is worth noting that this increased risk is not attributed to vitamin C obtained from food sources.
While the exact reasons for this association are not yet fully understood, it is advisable to exercise caution when taking high-dose vitamin C supplements, especially in individuals who may already be at risk for kidney stones.
It is important to maintain a balanced and varied diet that includes vitamin C-rich foods, as they provide numerous health benefits. However, if considering vitamin C supplementation, it is recommended to consult with a healthcare professional to determine the appropriate dosage and to discuss any potential risks or concerns, especially for individuals with a history of kidney stones.
7.Explore herbal remedies
Chanca Piedra, commonly known as the "stone breaker," is a popular herbal remedy in folk medicine believed to aid in the prevention of calcium-oxalate kidney stones and reduce the size of existing stones.
However, it's important to exercise caution when using herbal remedies, including Chanca Piedra, as they are not extensively regulated or thoroughly researched for the specific purpose of preventing or treating kidney stones.
While some anecdotal evidence and traditional use suggest potential benefits, it is always advisable to consult with a healthcare professional before starting any herbal supplement. They can provide personalized guidance based on your medical history, current medications, and overall health condition.
When considering herbal remedies, it's important to be well-informed and make informed decisions about their use. Additionally, it is recommended to purchase herbal supplements from reputable sources to ensure product quality and safety.
How to prevent kidney stones with medication
1. Talking to doctor about current medication
Certain medications, whether prescription or over-the-counter, have been associated with an increased risk of kidney stone formation. These medications include decongestants, diuretics, protease inhibitors, anticonvulsants, steroids, chemotherapy drugs, and uricosuric drugs.
It's important to note that the risk of kidney stones may vary depending on factors such as dosage, duration of use, and individual susceptibility. If you are currently taking any of these medications, it is crucial to consult with your doctor before considering any changes. Abruptly discontinuing prescribed medications without medical guidance can have unintended consequences.
Your healthcare provider can assess your specific situation, evaluate the potential risks and benefits, and explore alternative medication options if necessary. They will consider factors such as your medical history, current condition, and any other medications you may be taking to ensure the most appropriate treatment plan for you.
2. Talk to your doctor about preventive medication
If you are prone to certain types of kidney stones, there are specific medications that can be prescribed to help manage and control the formation of stones. The choice of medication will depend on the type of stones you typically experience.
- For calcium stones, a thiazide diuretic or phosphate medication may be recommended to help regulate the levels of calcium in your urine.
- Uric acid stones can be managed with the medication allopurinol (Zyloprim), which helps reduce the amount of uric acid in your blood and urine.
- Struvite stones may require long-term antibiotic treatment to reduce the presence of bacteria in your urine.
- Cystine stones can be addressed with the medication capoten (Captopril), which aids in reducing cystine levels in your urine.
It is important to note that the specific medication prescribed and the duration of treatment will be determined by your healthcare provider based on your individual circumstances and stone composition. They will consider factors such as the type of stone, your medical history, and any underlying conditions before recommending the appropriate medication regimen.
Bottom Line
Kidney stones are a common condition, and while there is no guarantee that prevention methods will completely eliminate the risk, they can help reduce the likelihood of developing stones. Staying hydrated by drinking an adequate amount of water and making certain dietary changes are key strategies for prevention.
If you have an underlying condition that increases your risk of kidney stones, such as inflammatory bowel disease, chronic urinary tract infections, or obesity, it's important to discuss with your doctor how to manage and address these conditions effectively to minimize the risk of kidney stone formation.
