Pancreatitis itself is a cause of back pain and abdominal pain
Pseudocyst with secondary infection can also cause the same.
If acute pancreatitis
progresses to chronic stage, obstruction of the pancreatic duct
can lead to pain.
Since pancreas is the source of insulin, patients with chronic pancreatitis can have diabetes. High cholesterol
(triglycerides) itself is a cause of pancreatitis.
Pain due to acute pancreatitis is usually severe and is associated with vomitting. Chronic pancreatitis patients have dull aching pain.
