What is Zollinger-Ellison Syndrome?

An uncommon disorder resulting in diarrhea and multiple peptic ulcers. The cause is a pancreatic tumor or enlarged pancreas, which in turn lead to high levels of the hormone gastrin, which stimulates excess production acidic gastric juice, causing the ulceration. Surgery is usually effective.
