Kidney Stones: Symptoms, Treatment and Prevention

What kidney stones are, why they form, the symptoms, and how they are treated and prevented.

Last updated: 24/9/2026

Kidney stones are hard deposits of minerals and salts that form inside the kidney. They are common in India and can cause intense pain when they move into the urinary tract.

Symptoms

  • ✓Severe cramping pain in the back or side
  • ✓Pain moving to the lower abdomen or groin
  • ✓Blood in urine
  • ✓Nausea and vomiting
  • ✓Burning when passing urine

Why they form

  • ✓Not drinking enough water — a big factor in hot climates
  • ✓High salt and high oxalate diet
  • ✓Obesity and metabolic conditions
  • ✓Family history

Treatment and prevention

Small stones often pass with fluids and pain relief; larger ones may need lithotripsy or surgery. Drinking enough water is the single best prevention.

Frequently Asked Questions

Can kidney stones cause kidney failure?

Repeated stones, obstruction or infection can damage kidneys over time, but most stones do not lead to failure if treated.

What foods cause stones?

Excess salt, animal protein, and very high-oxalate foods (spinach, nuts, beets) can contribute in stone-prone people.
