The gallbladder is an organ in your belly near the liver. It stores bile, which is a juice that helps you digest your food. Gallstones are like pebbles that form inside the gallbladder. Your gallbladder may be irritated and have stones in it. It may burst open and cause an infection in your belly. Your doctor will treat you based on how much pain you are in, how big the stones are, and if your gallbladder is inflamed or infected. Small gallstones may be helped with drugs that can dissolve them. The drugs may be taken by mouth or injected into the gallbladder. Bigger gallstones may need to be removed by surgery. Most often, gallbladder disease that causes pain and infection is treated with surgery.
