How to Prevent Kidney Stones in Diabetes?

Millions of people around the world manage diabetes, it is a chronic condition affecting how your body regulates blood sugar.  While managing blood sugar levels is a primary concern, diabetes can also increase the risk of other health complications, including kidney stones.  Kidney stones, those hard deposits that form in your kidneys, are notoriously uncomfortable and can even lead to serious health problems if left untreated. In this article, we will discuss the preventive strategies for kidney stones in diabetes.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) estimates that over 30 million Americans have diabetes, and kidney stones affect roughly 1 in 11 people at some point in their lives.  Unfortunately, research shows that diabetic individuals are more susceptible to developing kidney stones.  The sharp pains, nausea, and difficulty passing urine associated with kidney stones can significantly impact your quality of life.  Thankfully, there are steps you can take to prevent these unwanted guests from forming in your kidneys in the first place.

The Link Between Diabetes and Kidney Stones

Healthy kidneys act as a filtration system, removing waste products and excess fluid from your blood before sending them out as urine.  However, diabetes throws a wrench into this delicate process.  Chronically high blood sugar levels can damage the tiny blood vessels in your kidneys, hindering their ability to function properly.  This can lead to increased protein leakage into the urine, a condition known as proteinuria, which can further complicate kidney function.

Beyond harming the filtration system itself, diabetes also affects the composition of your urine.  When your blood sugar is high, your body tries to get rid of the excess through urine.  This can lead to a more concentrated urine environment, creating a breeding ground for kidney stones to form.

The most common type of kidney stone, calcium oxalate stones, are particularly troublesome for diabetics.  High blood sugar levels can promote the production of oxalate, a substance that combines with calcium to form these hard deposits.  While other types of stones exist, including uric acid and struvite stones, diabetes primarily contributes to the formation of calcium oxalate stones.

It’s important to remember that only diabetes isn’t responsible for kidney stones.  Several other factors can also increase your risk, including:

  • Family history: If someone in your close family has had kidney stones, you are more likely to develop them as well.
  • Dehydration: Not drinking enough fluids is a major risk factor for kidney stones. Dehydration allows urine to become concentrated, making it easier for stones to form.
  • Certain medications: Some medications, such as diuretics, can increase your risk of kidney stones.
  • Diet: A diet high in sodium, animal protein, and oxalates can contribute to stone formation.

Understanding how diabetes affects your kidneys and urine composition, along with other risk factors, is the first step toward preventing these painful stones.

How to Prevent Kidney Stones in Diabetes

Since diabetes and kidney stones often go hand-in-hand, adopting a healthy lifestyle becomes even more crucial. Here are some key strategies you can implement to prevent kidney stones while managing your diabetes:


A healthy diet is the cornerstone of both diabetes and kidney stone prevention. One approach that ticks both boxes is the DASH (Dietary Approaches to Stop Hypertension) diet.  This heart-healthy plan emphasizes fruits, vegetables, whole grains, low-fat dairy, and lean protein sources.  These foods are packed with essential nutrients and fiber, which can help regulate blood sugar levels and reduce urinary stone formation.

  • Protein intake: While protein is a vital nutrient, excessive intake, particularly from animal sources, can elevate uric acid levels in your urine, increasing the risk of uric acid stones.  Focus on moderate protein consumption and watch portion sizes.  Think of a serving size being roughly the size of a deck of cards.
  • Fluid intake:  Staying well-hydrated is the single most effective strategy for preventing kidney stones.  Aim to drink plenty of fluids throughout the day, with a goal of 6-8 glasses of water.  Consider including beverages like low-sugar citrus juices, as these often contain citrate, a substance that can help prevent stone formation.
  • Foods to limit:  Certain foods can contribute to kidney stone formation.  Here’s what to limit:
    • Sodium: A high-salt diet can increase calcium excretion in your urine, promoting stone formation. Cut back on processed foods, canned goods, and added table salt.
    • Oxalate-Rich Foods: Certain vegetables and fruits are high in oxalate, a component of calcium oxalate stones. While not entirely eliminating these foods, moderate your intake of spinach, rhubarb, beets, and nuts.
    • Animal Protein: As mentioned earlier, excessive animal protein intake can increase uric acid levels. Limit red meat, organ meats, and processed meats.


  • Manage Your Weight:  Maintaining a healthy weight can significantly benefit both your diabetes and kidney health.  Excess weight puts additional stress on your kidneys, potentially contributing to stone formation.
  • Regular exercise:  Regular exercise offers a multitude of benefits, including improved blood sugar control and overall health.  Exercise also helps you maintain a healthy weight and promotes better hydration.  Remember to stay hydrated during and after exercise sessions.

Medical Management:

If you are a diabetic and want to prevent kidney stones, some tests are very important to perform frequently. Here are some tests that people with diabetes should have done frequently to monitor their kidney health and potentially prevent kidney stones:

  • Urinalysis: This is a simple test that checks your urine for signs of infection, blood, and other abnormalities.  A urinalysis can also measure your urine’s pH level.  Having diabetes can increase your risk of having acidic urine, which can contribute to uric acid stones.
  • 24-Hour Urine Collection: This test collects all of your urine over a 24-hour period. This allows doctors to measure the total amount of urine you produce and the levels of different chemicals in your urine, such as calcium, oxalate, and uric acid.  These levels can help determine your risk of forming specific types of kidney stones.
  • Blood Tests: Blood tests can check your kidney function and measure the levels of electrolytes in your blood, such as calcium, phosphorus, and uric acid. Abnormal levels of these electrolytes can increase your risk of kidney stones.  Blood tests can also assess your diabetes control by measuring your blood sugar (glucose) and hemoglobin A1c (HbA1c) levels.

You can significantly reduce your risk of developing kidney stones while effectively managing your diabetes, by implementing these preventive strategies and working closely with your doctor.  Remember, a proactive approach is key to maintaining good health and preventing complications on both fronts.

Some Additional Tips

While diet, lifestyle changes, and medical management form the core of your preventive plan, here are some additional tips to consider:

  • Quality Sleep: Aim for sufficient sleep, typically 7-8 hours per night. Adequate sleep is essential for overall health and can also positively impact kidney function.
  • Reducing Stress: Chronic stress can contribute to various health problems, including kidney stones. Explore relaxation techniques like deep breathing, meditation, or yoga to manage stress levels.
  • UTIs Tracking: Early detection and treatment of urinary tract infections (UTIs) can help prevent kidney stones. UTIs can sometimes lead to stone formation, so be mindful of any urinary discomfort and consult your doctor if needed.

Remember, preventing kidney stones involves a multi-faceted approach. By incorporating these additional tips alongside the core strategies, you can empower yourself to take charge of your health and minimize your risk of these painful complications.
