Most people recover in a few days. The goal of treatment is to manage symptoms during this time. Choices are:

  • Supportive care, such as drinking extra fluids or getting fluids through an IV
  • Dietary changes, such as a low fat diet or nutrition given through a tube that is passed through the nose and into the stomach
  • Medicines to ease pain

People who are not helped by these methods may need surgery. The type of surgery done depends on the reason for the pancreatitis. Some choices are:

  • Percutaneous catheter drainage to drain fluid from the pancreas
  • ERCP to remove gallstones
  • Cholecystectomy to remove the gallbladder if gallstones are the cause
  • Necrosectomy to remove dying or dead tissue from the pancreas


To lower the risk of this health problem:

  • Manage chronic health problems, such as high triglycerides and obesity
  • Limit alcohol
