What are Gallbladder Stones?

Understanding Gall Stones:

Gallbladder is a small organ situated near the Liver. The function of gallbladder is to store and release bile into the small intestine. Bile is a digestive juice that is important for the metabolism of fat. Bile is made up of cholesterol, salts, bilirubin, water along with some other substances. It has a certain solubility and concentration. Due to some reasons, the bile can concentrated or thick and form hard pebble like stones called gall stones.


  • Cholesterol stones: These are made predominantly of precipitated cholesterol. Pure cholesterol stones are not common as gall stones mostly have other substances combined.
  • Pigmented stones: These are formed due to excess of bilirubin. They combine with calcium ions to form stones.
  • Mixed stones: This is the most common variety. These stones are made up of cholesterol, calcium salts, proteins, etc.

Gall stones are very common and affect about 10 million cases every year in India.
