Atrophic gastritis is a common type of gastritis, which is caused by the atrophy of gastric glands. The main clinical symptoms are as follows: 1. Some patients are prone to acid reflux, heartburn, belching and burping, which are mainly caused by excessive secretion of gastric acid; 2. Some patients may experience abdominal distension, abdominal pain, early satiety and no hunger, which are mainly symptoms triggered by reduced secretion of gastric acid, resulting in weakened digestive function. The diagnosis can be clarified by checking gastric fluid analysis gastrin determination, gastroscopy and pathology examination. The main treatment is to eradicate H. pylori, increase gastrointestinal motility and increase mucosal nutrition, which can be treated with oral morpholine, pancreatic enzyme tablets, compound digestive enzymes, vitamin B12 and other drugs.
