Pancreatitis is inflammation of the pancreas. The pancreas is a large gland behind the stomach and close to the duodenum - the first part of the small intestine. The pancreas secretes digestive juices, or enzymes, into the duodenum through a tube called the pancreatic duct. Pancreatic enzymes join with bile - a liquid produced in the liver and stored in the gallbladder - to digest food. The pancreas also releases the hormones insulin and glucagon into the bloodstream. These hormones help the body regulate the glucose it takes from food for energy.

Normally, digestive enzymes secreted by the pancreas do not become active until they reach the small intestine. But when the pancreas is inflamed, the enzymes inside it attack and damage the tissues that produce them.

Pancreatitis can be acute or chronic. Either form is serious and can lead to complications. In severe cases, bleeding, infection, and permanent tissue damage may occur.

Both forms of pancreatitis occur more often in men than women.

Acute pancreatitis is inflammation of the pancreas that occurs suddenly and usually resolves in a few days with treatment. Acute pancreatitis can be a life-threatening illness with severe complications. Each year, about 210,000 people in the United States are admitted to the hospital with acute pancreatitis.¹ The most common cause of acute pancreatitis is the presence of gallstones - small, pebble-like substances made of hardened bile - that cause inflammation in the pancreas as they pass through the common bile duct. Chronic, heavy alcohol use is also a common cause. Acute pancreatitis can occur within hours or as long as 2 days after consuming alcohol. Other causes of acute pancreatitis include abdominal trauma, medications, infections, tumors, and genetic abnormalities of the pancreas.
