Why does pancreatitis cause vomiting?

Inflammation in and around the pancreas can affect nearby digestive organs and the nerves that coordinate nausea and vomiting. The body may respond to severe upper abdominal pain by slowing normal stomach movement, which can leave food and fluid sitting in the stomach for longer. Vomiting is a common presentation of Pancreatitis; it does not by itself identify the cause of vomiting.

An episode can also bring poor appetite, abdominal swelling, tenderness, fever, or pain that reaches the back. Repeated vomiting can make it difficult to replace lost fluid and can leave you weak or dizzy.

Contact a clinician promptly if you have suspected or confirmed pancreatitis with vomiting. Assessment may include checking your circulation and hydration, examining your abdomen, and deciding whether you need blood tests, scans, pain relief, anti-sickness treatment, or fluids. Avoid alcohol while waiting for advice.

If you are able to drink, use small frequent sips rather than large amounts at once. Note the number of vomiting episodes, the colour of any vomit, the location of pain, and whether you have passed urine; these details are useful during assessment.

Get urgent medical help for severe or increasing abdominal pain, repeated vomiting, inability to keep fluids down, blood or coffee-ground-looking vomit, black stools, fever, fainting, confusion, yellow skin or eyes, or breathing difficulty. Do not drive yourself if you feel faint or severely unwell.

Ask whether your symptoms fit an acute pancreatic episode, how dehydration will be checked, which medicines are appropriate for vomiting, and which foods or drinks to avoid during recovery. Ask what follow-up is needed if vomiting returns.
