Signs and symptoms of Zollinger-Ellison syndrome may include:
- Abdominal pain
- Burning, aching, gnawing or discomfort in your upper abdomen
- Acid reflux and heartburn
- Nausea and vomiting
- Bleeding in your digestive tract
- Unintended weight loss
- Decreased appetite
When to see a doctor
See your doctor if you have a persistent, burning, aching or gnawing pain in your upper abdomen, especially if you've also been experiencing nausea, vomiting and diarrhea.
Tell your doctor if you've used over-the-counter acid-reducing medications such as omeprazole (Prilosec), cimetidine (Tagamet), famotidine (Pepcid) or ranitidine (Zantac) for long periods of time. These medications may mask your symptoms, which could delay your diagnosis. If you have Zollinger-Ellison syndrome, early detection and treatment are important.
