gastrin-secreting tumors

Gastrin-secreting tumors, also known as gastrinomas, are rare tumors that produce excessive amounts of the hormone gastrin. Gastrin stimulates the stomach to produce more acid, which can lead to stomach ulcers, gastroesophageal reflux, and other digestive issues. These tumors often occur in the pancreas or the duodenum (part of the intestine) and may be part of a condition called Zollinger-Ellison syndrome. Diagnosing gastrinomas typically involves blood tests and imaging studies. Treatment usually includes medications to reduce stomach acid and, in some cases, surgery to remove the tumor.
