May also be called: Gallstones
Cholelithiasis (ko-leh-lih-THY-uh-sis) is the medical term for the presence of
gallstones, which are hard, pebble-like objects made of bile that form in the gallbladder.
More to Know
The gallbladder is a small organ just below the liver in the top right of the belly.
It stores bile, a fluid produced by the liver to help digest fat in the foods we eat.
Sometimes, material in the bile sticks together and forms hard, pebble-like objects
(gallstones). There are two main types of gallstones: those made from cholesterol
and those made from bilirubin
(a pigment made by the breakdown of red blood cells). Gallstones can happen in people
with sickle cell
disease or other conditions, or who are receiving certain treatments.
Many people who have gallstones don't have any symptoms. But if a gallstone gets
stuck going out the opening of the gallbladder, it can cause pain in the top
or the top right of the belly, below the right shoulder blade, or in the back. The
pain may get worse after eating fatty foods. A person with gallstones also might
have nausea or vomiting.
Sometimes, small gallstones leave the body on their own, and those that do not
cause symptoms or problems might not need treatment. But gallstones that cause symptoms
often need to be treated with gallbladder-removal surgery. After surgery, gallstones
will not return. Sometimes, medicine is used to dissolve gallstones made of cholesterol,
but it can take years to work and new gallstones can still develop after treatment.
Keep in Mind
People who have had gallstones sometimes get them again, and those who didn't have
symptoms from previous gallstones may develop them. Contact your doctor if symptoms
appear.
