Acute pancreatitis is sudden inflammation of the pancreas. The pancreas is an organ that sits behind the stomach. It makes fluids that help break down food in the small intestine.

Causes may be:
- Gallstones that block fluid from leaving the pancreas
- Alcohol use disorder
- Certain medicines, such as corticosteroids, opioids, and valproate
- High triglyceride levels
- Abdominal trauma
- Complications of endoscopic retrograde cholangiopancreatography (ERCP)
Sometimes the cause is not known.
The risk of this problem is higher in people who have any of the causes listed above.
Other things that may raise the risk of this problem are:
The main problem is mild to severe pain in the center of the belly. It may also spread into the upper back. This pain may last several days.
A person with acute pancreatitis may also have:
- Swollen belly
- Nausea and vomiting
The doctor will ask about your symptoms and health history. You may be asked about your use of alcohol. A physical exam will be done.
Tests may also be done. They include:
Any underlying causes will need to be treated.
Most people recover in a few days. The goal of treatment is to manage symptoms during this time. This may be done with:
- 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. A person may have:
- 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
