Chronic pancreatitis is long-term inflammation of the pancreas that creates constant pain in the upper abdomen, reports WebMD. The pain radiates to the back and may be immobilizing for some patients. Acute pancreatitis is the other type of pancreatitis, and it usually occurs before chronic pancreatitis.
Acute pancreatitis is an abrupt inflammation that lasts for a short period of time, states WebMD. The condition can be mild to life-threatening. The symptoms include upper abdominal pain, fever, nausea, a swollen abdomen and a raise in heart rate. Individuals with these symptoms should seek medical attention. Acute pancreatitis is caused by gallstones, excessive alcohol use, medications, infections and metabolic disorders.
