What is Gallstones?

Gallstones are hardened deposits that form in the gallbladder, usually made of cholesterol, and are very common, though most people with gallstones have no symptoms at all. When they do cause symptoms, this typically involves sudden, intense pain in the upper right abdomen, often after eating fatty food, sometimes alongside nausea.

Gallstones causing symptoms or complications, such as blocking the bile duct or causing gallbladder inflammation (cholecystitis), are usually treated by surgically removing the gallbladder, which resolves the problem completely since the gallbladder isn't essential for digestion.
