Gastrinoma: What It Is and How It Affects You

A gastrinoma is a rare tumor that usually grows in the pancreas or duodenum and produces too much gastrin hormone. Too much gastrin makes the stomach pump out extra acid, which can burn the lining of the stomach and intestine. This condition is often called Zollinger‑Ellison syndrome. If you’ve heard the term but aren’t sure what it means, you’re in the right place.

Most people with gastrinoma don’t notice anything until the acid starts causing problems. The excess acid can lead to persistent heartburn, ulcers that won’t heal, and sometimes pain after meals. Because the symptoms look like common reflux or ulcer disease, many patients get treated for those first before the real cause is found.

Signs and Symptoms You Should Notice

Typical signs include:

• Severe, burning heartburn that doesn’t improve with over‑the‑counter meds.
• Recurrent or multiple stomach ulcers, especially in unusual spots.
• Frequent diarrhea or oily stools caused by acid damaging the intestines.
• Unexplained weight loss or loss of appetite.
• Abdominal pain that gets worse after eating.

If you experience several of these, especially together, it’s worth mentioning gastrinoma to your doctor. Early detection makes treatment much easier.

How Doctors Diagnose and Treat Gastrinoma

Doctors start with a blood test to check gastrin levels. Very high gastrin, combined with a low stomach pH, points strongly to a gastrinoma. Imaging studies—like CT scans, MRI, or an endoscopic ultrasound—help locate the tumor.

Once the tumor is found, treatment usually involves two steps: controlling acid production and removing the tumor. Proton‑pump inhibitors (PPIs) are the go‑to drugs for acid control; they can keep symptoms in check while the tumor is being addressed.

Surgical removal is the preferred cure, especially for small, confined tumors. Larger or spread‑out tumors may need additional treatments such as targeted therapy, chemotherapy, or peptide‑receptor radionuclide therapy (PRRT). Your doctor will choose the best plan based on tumor size, location, and whether it has spread.

Living with gastrinoma means regular follow‑up. Even after surgery, doctors monitor gastrin levels and run periodic scans to catch any recurrence early. Lifestyle tweaks—like avoiding alcohol, nicotine, and spicy foods—can also reduce acid irritation.

Bottom line: gastrinoma is a rare but treatable cause of extreme stomach acid. Spotting the signs early, getting the right tests, and following a clear treatment plan can get you back to feeling normal. Keep an eye on your symptoms, talk to your doctor, and use the resources here to stay informed.
