Consequently, what material composes the most common type of gallstones?
The most common type of gallstone, called a cholesterol gallstone, often appears yellow in color. These gallstones are composed mainly of undissolved cholesterol, but may contain other components.
Furthermore, what is the main cause of gallstones?
Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.
CONCLUSIONS: Patients with at least 1 gallstone smaller than 5 mm in diameter have a more than 4-fold increased risk of presenting with acute biliary pancreatitis. A policy of watchful waiting in such cases is unwarranted.
