Gallstones are crystallized components of bile in your gallbladder. There are two types, pigment stones and cholesterol stones.

• Pain in the abdomen
• indigestion, nausea, or vomiting

Cholesterol stones occur when too much cholesterol builds up in the bile secreted from the liver.

Pigment stones occur when the gallbladder cannot break down excess space bilirubin.

It can be surgically removed or you can take medication.
