The liver is the second largest organ in the human body and one of the most important organs we have. The liver performs multiple functions, such as flushing out harmful toxins, processing food, producing bile, maintaining blood sugar levels, etc. 

Gallstones can lead to the inflammation of the pancreas (pancreatitis). This happens when the gallstone traveling through the bile duct obstructs the pancreatic duct, which joins the duct passing from the liver to the intestine.
