Risk factors
By Mayo Clinic staffFactors that increase your risk of developing kidney stones include:
- Family or personal history of kidney stones. If someone in your family has kidney stones, you're more likely to develop stones, too. And if you've already had one or more kidney stones, you're at increased risk of developing another.
- Being an adult. Kidney stones are most common in adults age 40 and older, though kidney stones may occur at any age.
- Being a man. Men are more likely to develop kidney stones.
- Dehydration. Not drinking enough water each day can increase your risk of kidney stones. People who live in warm climates and those who sweat a lot may need to drink more water than others.
- Certain diets. Eating a diet that's high-protein, high-sodium and high-sugar may increase your risk of some types of kidney stones.
- Being obese. High body mass index (BMI), increased waist size and weight gain have been linked to an increased risk of kidney stones.
- Digestive diseases and surgery. Gastric bypass surgery, inflammatory bowel disease or chronic diarrhea can cause changes in the digestive process that affect your absorption of calcium and increase the levels of stone-forming substances in your urine.
- Other medical conditions. Diseases and conditions that may increase your risk of kidney stones include renal tubular acidosis, cystinuria, hyperparathyroidism and certain urinary tract infections.
