The main factor that stimulates the gastric glands is food, which enters the mouth, throat, and esophagus, and stimulates them to secrete saliva and other digestive juices in the mouth. When food enters the gastrointestinal tract, it will stimulate the stomach, stimulate the peristalsis of the intestinal mucosa, and promote the secretion of gastric glands. And the excessive secretion of adrenaline in the body can also promote the secretion of gastric juice. If the patient eats more food containing calcium ions or drinks alcohol, it can promote the secretion of gastric juice and the peristalsis of the intestines. Especially after eating stimulating food, it will also stimulate the gastric mucosa to secrete gastric juice. For example, spicy and stimulating food will stimulate the stomach after consumption. In addition, the vagus nerve can also stimulate the gastric glands and promote the secretion of gastric juice.
