Gastrinomas are neuroendocrine tumours (NETs) that start in cells that make the hormone gastrin. Most gastrinomas start in the small bowel (duodenum) and the pancreas. 

They are a type of functioning NET of the pancreas.

What are gastrinomas?

Gastrinomas are rare NETs that make large amounts of the hormone gastrin.

Symptoms of gastrinoma

Possible symptoms of gastrinoma include tummy (abdominal) pain and loose or watery poo (diarrhoea).

Diagnosing gastrinoma

You have some tests to diagnose a gastrinoma. This might include blood tests and a test to look at the inside of your food pipe, stomach and small bowel. 

Stages and grades of pancreatic NETs

The stage and grade of a pancreatic NET helps your doctor decide which treatment you need.

Treatment for gastrinoma

The treatment you have depends on a number of things such as where the gastrinoma is, its size and whether it has spread.

Research and clinical trials for pancreatic NETs

Researchers are looking at improving the diagnosis, treatment and quality of life of people with pancreatic NETs.

Follow up for gastrinoma

You have follow up appointments to check how you are and see if you have any problems or worries.

Risks and causes of pancreatic NETs

There are some factors that increase your risk of developing a pancreatic NET. This includes some medical conditions.

Living with NETs

Get practical and emotional support to help you cope with a neuroendocrine tumour.

Survival for gastrinoma

Survival for gastrinomas depends on different factors. So no one can tell you exactly how long you will live.
