Pancreatitis is most commonly caused by excessive use of alcohol or by a blockage of the tube (duct) that leads from the pancreas to the beginning of the small intestine (duodenum), usually by a gallstone. Other causes include an infection, an injury, or certain medicines. It may develop suddenly (acute), or it may be a long-term, recurring (chronic) problem.
Treatment in the hospital includes pain medicine and fluids given through a vein (IV) until the inflammation goes away. Nutrition is given through a tube to avoid stimulating the pancreas. Although most people recover fully from pancreatitis, complications such as bleeding, infection, or organ failure may occur.
