Because diseases such as pancreas and biliary tract can also cause the same symptoms as this disease, it is necessary to distinguish them. It should be differentiated from erosive gastritis, gastric ulcer and duodenal ulcer with hyperacidity.
True hyperacidity is a completely functional disease. When it happens, the movement of the stomach is also hyperactive, and the tension of the stomach is increased, which is easily influenced by the spirit to aggravate the secretion of gastric juice and the movement of the stomach, leading to the deterioration of symptoms. It is not only sensitive to mental stimulation, but also easy to react to food stimulation.
Hyperacidity is an unstable state of autonomic nerve, which is characterized by the appearance or disappearance of symptoms due to mental stress. Generally more common in young people.
There are also many cases of hyperacidity caused by physical reasons. In addition, gastrin hormone secreted near the pylorus of stomach can promote the secretion of hydrochloric acid. Therefore, the number and function of gastrin-secreting cells also have a great influence on the acidity of gastric juice. In other words, hyperacidity is two important factors of vagus nerve excitation and hypergastrin secretion.
Duodenal ulcer mostly shows hyperacidity, but the acidity and secretion of gastric juice in gastric ulcer are not very high or even very low.
