Understanding Lab Tests for Gastric Hypersecretion

Gastric hypersecretion is a condition characterized by the excessive production of gastric acid in the stomach. This overproduction can lead to various digestive issues, including peptic ulcers, gastroesophageal reflux disease (GERD), and abdominal pain. Blood testing plays a crucial role in diagnosing the underlying hormonal causes of this condition.

How Blood Tests Diagnose Gastric Hypersecretion

While symptoms like heartburn, stomach pain, and nausea may suggest gastric hypersecretion, a definitive diagnosis requires measuring specific hormones that regulate stomach acid production. Gastrin, a key hormone that stimulates gastric acid secretion, is the primary biomarker used to identify this condition.

Understanding Gastrin and Acid Production

Gastrin is produced by specialized cells in the stomach and small intestine. When gastrin levels are abnormally high, it can indicate conditions such as Zollinger-Ellison syndrome, gastrinomas (gastrin-producing tumors), or other disorders that cause excessive acid production. Early detection through gastrin testing is essential for preventing complications like severe ulcers and bleeding.
