Clinically, the diagnosis of “chronic gastritis” is as widespread as the diagnosis of “coronary heart disease,” which is actually incorrect. The diagnosis of chronic gastritis does not rely on symptoms, but mainly on endoscopy and pathology, which has the greatest diagnostic value. Endoscopic classification of chronic gastritis into non-atrophic (superficial) gastritis, atrophic gastritis and specific types of gastritis is diagnosed with erosion, bleeding, and bile reflux if they are also present. The endoscopic judgment of the severity of chronic gastritis is unreliable, and the operator’s subjective factor is obvious. Regarding treatment: 1. Remove the causes, such as irregular diet, strong tea, alcoholism, smoking, emotional instability, poor sleep, etc. Pay attention to chewing and do not eat with one mind. 2, HP positive with celiac disease, atrophy, dyspepsia symptoms need to eradicate HP, many programs, commonly used omeprazole 20mg bid + amoxicillin 1g bid + clavulanic acid 0.5 bid × 7 to 14 days. After the end of treatment, 1 month review to determine whether HP is eradicated. 3. Prokinetic drugs can be applied to those with upper abdominal fullness, nausea or vomiting as the main symptoms. Such as morpholine, mosapride. Those with gastric mucosal erosion and/or with symptoms such as acid reflux and epigastric pain should choose H-receptor antagonists or proton pump inhibitors (PPI) therapy. For example, Gosudar, Loxac (omeprazole), Nexium, etc. From personal experience, if only gastric mucosal protective agents are given at this time, the effect is not good. Excess acid can be treated with additional antacids, such as sodium bicarbonate. In case of bile reflux and mucosal erosion, gastric mucosal protective agents can be added. Such as bismuth, aluminum thioglycollate, gastric soporific. We commonly use Daxil (magnesium aluminum carbonate). Stasol is mainly for antacid and gastric mucosal protection. Antidepressants or anxiolytics can be used in patients with chronic gastritis with dyspeptic symptoms who have significant psychiatric factors.
