Pancreatitis is inflammation of the pancreas. It is characterised by the sudden onset of upper abdominal pain which may be accompanied by nausea & vomiting.
Pancreatitis is most commonly acute, however there is a chronic form. Acute pancreatitis is most commonly due to gallstones or alcohol use. These two causes account for 60 to 75% of cases. While there are rare causes such as autoimmune, viral or medication induced, the next largest group is of unknown cause representing about 20% of cases.
