Zollinger-Ellison syndrome is a rare disorder that arises from tumors and ulcers in the digestive system. One or more tumors form in the pancreas or duodenum (the upper part of the small intestine). Not only can these tumors lead to ulcers, they can also be cancerous, and spread to the nearby lymph nodes or liver.
About one-quarter of people with Zollinger-Ellison syndrome have a genetic disorder called multiple endocrine neoplasia type 1 (MEN 1). People with MEN 1 may have additional endocrine tumors in the brain and neck.

Zollinger-Ellison syndrome is caused by gastrin-producing tumors, called gastrinomas. Gastrin is a hormone that stimulates the stomach to produce acid. Excess acid production may lead to ulcers
Factors that increase your chance of getting Zollinger-Ellison syndrome include:
- Your or family members with MEN 1
- History of endocrine disorders
- Recurrent peptic ulcers
In many people, Zollinger-Ellison syndrome causes symptoms similar to an ulcer or
gastroesophageal reflux disease
Symptoms may include:
- Abdominal pain
- Nausea or vomiting
- Weight loss
- Blood in the vomit or stool
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
- Blood tests
- Upper gastrointestinal endoscopy—a flexible tube with a light and camera is inserted down the throat and into the stomach and intestine to look for ulcers
tests allow your doctor to see internal body structures. These tests may include:
Talk with your doctor about the best treatment plan for you. Options include:
of the gastrin-secreting tumors may be attempted. This may not be possible though if there are multiple tumors, or if cancer cells have spread to other parts of the body.
Zollinger-Ellison syndrome may be treated with:
- Proton pump inhibitors
- Somatostatin analogs to control tumor growth
- Chemotherapy may be used in those who have rapidly growing tumors or for tumors that can't be removed
There are current guidelines to prevent Zollinger-Ellison syndrome. If you have a family history of Zollinger-Ellison syndrome or MEN 1, consider contacting a genetic counselor for screening.
