Acute pancreatitis

Acute pancreatitis is a sudden inflammation of the pancreas, the gland behind the stomach that helps digest food and controls blood sugar. It causes severe pain and needs hospital care. Most people get better within about a week, but a few develop serious complications.

What it is

The two most common causes are gallstones and drinking alcohol. Less often it follows high triglycerides, some medicines or a procedure on the bile ducts.

Treatment is supportive: fluids, pain relief and nutrition, and dealing with the cause, for example removing the gallbladder or stopping alcohol.

Common signs

  • Sudden, severe pain in the upper belly that can spread to the back
  • Feeling or being sick
  • Fever and a fast heartbeat
  • Pain that is worse after eating

How it is usually diagnosed

  • Blood tests for pancreatic enzymes (amylase or lipase)
  • An ultrasound to look for gallstones
  • A CT scan in some cases, to check for complications

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood test results from the episode
  • Ultrasound and CT reports
  • Discharge letter naming the likely cause
  • Records of any later gallbladder surgery

Questions to ask your doctor

  • What caused my pancreatitis?
  • What can I do to stop it happening again?
  • Do I need follow-up scans or blood tests?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden severe pain in the upper belly
  • Repeated vomiting with pain
  • Feeling faint, clammy or breathless
