Belching up to not be able to block the panic may be related to chronic atrophic gastritis, gastric ulcer, gastroesophageal reflux disease. 1. Chronic atrophic gastritis: the vast majority of patients with chronic atrophic gastritis are infected with Helicobacter pylori. Helicobacter pylori contains the enzyme urease that breaks down urea to produce ammonia, which can neutralize the gastric acid that seeps back into the mucus. Stomach acid refluxes to the esophagus and throat when lying down, irritating the mucous membrane of the throat, and the patient may have the symptom of belching that can’t come up and block the panic. 2. Gastric ulcer: Most patients with gastric ulcer have excessive secretion of gastric acid. When food enters the stomach, it stimulates the cells of the stomach lining to secrete a large amount of gastric acid, which breaks down the food and produces a large amount of gas. The gastric acid refluxes into the esophagus and pharynx when lying down, stimulating the mucous membranes in the pharynx, thus making the patient suffer from belching and blockage. 3. Gastroesophageal reflux disease (GERD): Most of the patients with GERD have dysfunction or transient relaxation of the lower esophageal sphincter. When patients eat food, gastric pressure rises, the lower esophageal sphincter can not be timely contraction, resulting in gastric acid and part of the gastric contents of the reflux into the esophagus, pharynx, which makes the patient belching up to the blockage of panic symptoms. If you have belching symptoms, you should go to the hospital in time, perfect gastroscopy to clarify the cause of the disease, regular treatment so that the patient as soon as possible to recover.
