Gallstones are solid particles that are formed in the gallbladder which is a small sac like organ located below the liver on the right side of the abdomen and stores bile until needed.
Gallstones within the gallbladder usually don’t cause any symptoms unless they are arg ones or much in number and person takes heavy fatty meal. Another cause of pain could be obstruction if they block bile secretion from the gallbladder or they get stuck into the bile duct.
The size of the stone may vary from very small like a grain to as big as a golf ball and may be single or multiple in number.
There are two types of gallstones:
Cholesterol stones: are formed when there is excess of cholesterol in the bile.
Pigment stones: are formed when there is excess of bilirubin in the bile.
Major complication of an obstructed gallstone is inflammation of the gallbladder which is also known as cholecystitis and cause fever and pain.
Blockage of common bile duct may cause infection and jaundice.
Sometimes due to association of pancreatic duct with the common bile duct the stone may get lodged in the pancreatic duct and would cause obstruction. This would cause inflammation that is pancreatitis leading to intense pain.
Gallstones also increases chances of gallbladder cancer as well in future.
