"I Get Smashed" are the causes of Acute Pancreatitis

Acute pancreatitis is a sudden inflammation of the pancreas. Depending on its severity, it can have severe complications and high mortality despite treatment. While mild cases are often successfully treated with conservative measures, such as NPO(abstaining from any oral intake) and IV fluid rehydration, severe cases may require admission to the ICU or even surgery (often more than one intervention) to deal with complications of the disease process.

Severe epigastric pain radiating to the back.
Nausea, vomiting,diarrhea, and loss of appetite.

pancreatic cancer

A common mnemonic for the causes of pancreatitis spells "I get smashed", an allusion to heavy drinking (one of the many causes):

I - idiopathic
G - gallstone. Gallstones that travel down the common bile duct and which subsequently get stuck in the Ampulla of Vater can cause obstruction in the outflow of pancreatic juices from the pancreas into theduodenum. The backflow of these digestive juices causes lysis (dissolving) of pancreatic cells and subsequent pancreatitis.
E - ethanol (alcohol)
T - trauma
S - steroids
M - mumps (paramyxovirus) and other viruses (Epstein-Barr virus,Cytomegalovirus)
A - autoimmune disease (Polyarteritis nodosa, Systemic lupus erythematosus)
S - scorpion sting -Tityus Trinitatis -Trinidad/ snake bite
H - hypercalcemia,hyperlipidemia/hypertriglyceridemiaand hypothermia
E - ERCP (Endoscopic Retrograde Cholangio-Pancreatography - a procedure that combines endoscopyand fluoroscopy)
D - drugs (SAND-steroids &sulfonamides,azathioprine, NSAIDS,diuretics such asfurosemide andthiazides, & didanosine) and duodenal ulcers-wikipedia
