- Gallstones are small stones made from cholesterol, bile pigment and calcium salts, which form in a person’s gall bladder.
- Medical treatment isn’t necessary unless the gallstones cause symptoms.
- Treatment options include surgery and shattering the stones with soundwaves.
Causes
- Your bile contains too much cholesterol. Normally, your bile contains enough chemicals to dissolve the cholesterol excreted by your liver. But if your liver excretes more cholesterol than your bile can dissolve, the excess cholesterol may form into crystals and eventually into stones.
- Your bile contains too much bilirubin. Bilirubin is a chemical that’s produced when your body breaks down red blood cells. Certain conditions cause your liver to make too much bilirubin, including liver cirrhosis, biliary tract infections and certain blood disorders. The excess bilirubin contributes to gallstone formation.
- Your gallbladder doesn’t empty correctly. If your gallbladder doesn’t empty completely or often enough, bile may become very concentrated, contributing to the formation of gallstones.
Symptoms
-
Gallstones may cause no signs or symptoms. If a gallstone lodges in a duct and causes a blockage, the resulting signs and symptoms may include:
- Sudden and rapidly intensifying pain in the upper right portion of your abdomen
- Sudden and rapidly intensifying pain in the center of your abdomen, just below your breastbone
- Back pain between your shoulder blades
- Pain in your right shoulder
- Nausea or vomiting
