Why Do People Get Kidney Stones? Understanding the Causes

Kidney stones are hard mineral deposits that form inside the kidneys and can cause severe pain when they move through the urinary tract. They are a common health problem, but many people don’t know why they develop. Understanding the causes can help in prevention.

1. Not Drinking Enough Water

One of the biggest reasons people get kidney stones is dehydration. When you don’t drink enough water, urine becomes concentrated, allowing minerals and salts to stick together and form stones.

2. High Intake of Salt and Sugar

Eating too much salt increases calcium levels in urine, which raises the risk of stone formation. Excess sugar, especially from processed foods and sugary drinks, can also contribute to kidney stones.

3. Diet High in Certain Foods

Foods rich in oxalates—such as spinach, nuts, chocolate, tea, and beets—can increase the risk of stones in some people. Excessive animal protein (red meat, eggs) may also raise uric acid levels, leading to stone formation.

4. Family History and Genetics

If kidney stones run in your family, you may be more likely to develop them. Genetics can affect how your body processes minerals like calcium and oxalate.

5. Certain Medical Conditions

Conditions such as obesity, diabetes, gout, digestive disorders, and repeated urinary tract infections can increase the risk of kidney stones. Some intestinal diseases reduce calcium absorption, which leads to higher oxalate levels.

6. Certain Medications and Supplements

Some medicines, including diuretics and calcium-based antacids, can increase stone risk. Taking high doses of vitamin C or calcium supplements without medical advice may also contribute.

7. Holding Urine for Long Periods

Not urinating regularly allows minerals to stay longer in the kidneys, increasing the chance of stone formation.

Final Thoughts

Kidney stones develop due to a combination of lifestyle, diet, genetics, and medical factors. Staying well-hydrated, eating a balanced diet, and maintaining a healthy lifestyle can significantly lower your risk. If kidney stones occur frequently, it’s important to consult a healthcare professional for proper evaluation and prevention guidance.
