Description

Gastrin is a hormone produced by G cells in the lining of the stomach and the upper part of the small intestine (duodenum). It plays a crucial role in the digestive process by stimulating the secretion of gastric acid (hydrochloric acid) from the parietal cells of the stomach, which aids in food digestion and the absorption of nutrients.

Gastrin levels can be measured through blood tests to help diagnose various gastrointestinal disorders. Elevated levels of gastrin may indicate conditions such as Zollinger-Ellison syndrome, where tumors in the pancreas or duodenum produce excessive amounts of gastrin, leading to increased gastric acid production and recurrent peptic ulcers. Low gastrin levels can occur in conditions such as atrophic gastritis or following certain surgical procedures. Monitoring gastrin levels can help healthcare providers evaluate stomach acid production, diagnose gastrointestinal diseases, and guide treatment decisions.
