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, Zegerid), cimetidine (Tagamet) or famotidine (Pepcid) for long periods of time. These medications may mask your symptoms, which could delay your diagnosis.
