Definition

The pancreas sits behind the stomach. It makes fluids that help to break down food in the small intestine. This fluid can become active in the pancreas and cause irritation and inflammation. This is called pancreatitis.

Acute pancreatitis is a sudden start of the inflammation. For most this type will pass in a few days.
