Kidney Stones

What Causes Them?

No one knows the exact cause of kidney stones, and doctors can seldom explain why one person will get kidney stones and another person will not. However, research has shown that people with certain risk factors are more likely than others to develop the condition. (A risk factor is anything that increases a person's chance of developing a disease.)
 
Kidney stones risk factors include:
 
  • Age
  • Gender
  • Certain diets
  • Family history
  • Urinary tract infections and blockage of the urinary tract
  • Inherited diseases, such as cystinuria, hyperoxaluria, hypercalciuria, hyperuricosuria
  • Kidney disease, such as cystic kidney diseases
  • Medical conditions, like gout
  • Excess vitamin D intake
  • Metabolic disorders, such as hyperparathyroidism
  • Medications, such as diuretics, indinavir, or calcium-based antacids.
