Causes of Pancreatitis in Children
When the pancreas suddenly becomes inflamed, there are two common causes: gallstones and chronic alcohol consumption. Gallstones, or pebbles made of hardened bile, can trigger acute pancreatitis if they leave the gallbladder and pass through or get lodged in the common bile duct, the tube connecting the liver, gallbladder, and pancreas to the small intestine.

Excessive alcohol consumption is another leading cause of acute pancreatitis. The condition can develop within hours or up to two days after heavy drinking.

Other causes of acute pancreatitis may include:

High levels of fat in the blood
High levels of calcium in the blood
Abdominal injury that damages the pancreas
Hormonal abnormalities
Certain medications, such as steroids and estrogens
Viral infection
Genetic abnormalities of the pancreas
