Is any of this happening?
Be seen today
If you have a diagnosed gastrinoma, contact your treating team promptly if symptoms return despite acid-blocking medicine, you cannot keep the medicine down, swallowing becomes difficult, or diarrhea causes weakness or dehydration.
Report treatment side effects that interfere with daily life.

Does any of this apply?
Book an appointment
Arrange a medical appointment for recurring ulcer symptoms, ongoing watery diarrhea, unexplained weight loss or reflux that does not improve with usual treatment.
These symptoms have many possible causes and do not necessarily mean you have a gastrinoma.
Every sign above is quoted from the sofidex article on Gastrinoma. If you are not sure, err upward — it is always reasonable to be checked.
