Chronic pancreatitis is a permanent inflammation of the pancreas that does not heal or improve and alters the organ′s normal structure and functions. It is usually followed after an episode of acute pancreatitis. Heavy alcohol drinking is another major cause. Chronic pancreatitis can present as episodes of severe inflammation in an injured pancreas, or as chronic damage with persistent pain or malabsorption. Diabetes is a common complication arising due to the chronic pancreatic damage and requires treatment with insulin.
