What is Pancreatitis?

Pancreatitis is the inflammation and autodigestion of the pancreas. Autodigestion describes a process whereby pancreatic enzymes destroy its own tissue leading to inflammation. The inflammation may be sudden (acute) or ongoing (chronic). Acute pancreatitis usually involves a single "attack," after which the pancreas returns to normal. Severe acute pancreatitis can be life threatening. In chronic pancreatitis, permanent damage occurs to the pancreas and its function, often leading to fibrosis (scarring).
