This large secretion in the empty stomach without the buffering effect of food makes the gastric content very corrosive and, when it is hurried onward into the duodenum by the gastric hypermotility, produces the chronic progressive ulcer in the less resistant duodenal mucosa. The duodenum begins this process by preparing the chyme so that nutrients can then be absorbed easily.

Serum gastrin varied between <10 and 28pmol/L (reference interval <55), and was thus within normal interval in all patients. The buffering effect is when the stomach acid is met with bicarbonate to reach a stable pH so that the cyme can be digested by the small intestine. These secretions protect the duodenum against autodigestion by gastric acids that can cause duodenal ulcers. That means it prevents histamine release.
