Are Gallstones and Kidney Stones the Same?
Gallstones and kidney stones are both hard deposits in the body, but they differ in location, symptoms, causes, and treatment. Learn how to tell them apart and when to seek medical help.
If you've ever experienced sharp, sudden pain in your abdomen or back, you might have wondered whether it’s due to gallstones or kidney stones. While both conditions involve the formation of hard deposits in the body, they are different in many ways. Understanding these differences can help you identify symptoms early and seek the right treatment.
What Are Gallstones and Kidney Stones?
Gallstones
Gallstones are hardened deposits that form in the gallbladder, a small organ beneath the liver. The gallbladder stores bile, a digestive fluid that helps break down fats. Gallstones can be made of cholesterol (most common) or bilirubin (a pigment from bile).
Kidney Stones
Kidney stones are hard mineral and salt deposits that form in the kidneys. They can travel down the urinary tract, causing severe pain. Kidney stones are usually made of calcium oxalate, but other types include uric acid, struvite, and cystine stones.
Key Differences Between Gallstones and Kidney Stones
| Feature | Gallstones | Kidney Stones |
| Location | Gallbladder | Kidney or Urinary Tract |
| Composition | Cholesterol or bilirubin | Calcium oxalate, uric acid, etc. |
| Pain Location | Upper right abdomen, sometimes radiating to the back or shoulder | Lower back or side, radiating to the groin |
| Common Symptoms | Nausea, vomiting, bloating, indigestion | Painful urination, frequent urination, blood in urine |
| Rusk Factors | Obesity, high-fat diet, rapid weight loss | Dehydration, high-salt diet, family history |
Symptoms: How to Tell Them Apart

- Pain while urinating
- Pink, red, or brown urine (blood in urine)
- Frequent urge to urinate
- Cloudy or foul-smelling urine
What Causes Gallstones and Kidney Stones?
Gallstone Causes
- High cholesterol in bile (leading to cholesterol stones)
- Excess bilirubin (seen in liver diseases like cirrhosis)
- Gallbladder not emptying properly (bile becomes concentrated)
Risk factors: Obesity, diabetes, pregnancy, rapid weight loss
Kidney Stone Causes
Dehydration (not drinking enough water)
High-sodium or high-oxalate diet (spinach, nuts, chocolate)
Certain medical conditions (gout, urinary tract infections)
Family history of kidney stones
How Do They Affect Your Health?
Gallstones Complications
Blocked bile ducts (can cause jaundice or infection)
Gallbladder inflammation (cholecystitis)
Pancreatitis (if a stone blocks the pancreatic duct)
Kidney Stones Complications
Recurrent infections
Blockage of urine flow (can damage kidneys if untreated)
Chronic kidney disease (rare, but possible with frequent stones)
How to Manage and Prevent Them
For Gallstones
Eat a balanced diet (reduce fatty, fried foods)
Maintain a healthy weight (avoid rapid weight loss)
Stay hydrated (helps bile flow smoothly)
Exercise regularly (supports digestion)
For Kidney Stones
Drink plenty of water (at least 2-3 litres daily)
Limit salt and oxalate-rich foods (spinach, nuts, tea)
Eat calcium-rich foods (helps bind oxalates in the gut)
Reduce animal protein (high intake increases uric acid stones)
When to See a Doctor
Seek medical help if you experience:
Severe, unrelenting pain
Fever with chills (sign of infection)
Yellow skin/eyes (jaundice)
Blood in urine
- Nausea/vomiting that prevents eating
