Pancreatitis

Pancreatitis is inflammation of the pancreas. The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones.
There are two main types, acute pancreatitis and chronic pancreatitis. Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and vomiting. The pain often goes into the back and is usually severe.
The most common causes of acute pancreatitis are gallstones and heavy alcohol use.
