Chronic gastritis typically presents with symptoms such as belching, acid reflux, stomach bloating, stomach pain, nausea, and vomiting. A definitive diagnosis can be made through a gastroscopy, which may reveal signs of edema and hyperemia in the gastric mucosa, and in some cases, erosion. Poor gastric motility may lead to bile reflux, which can be observed during a gastroscopy as bile presence in the stomach. This condition, known as bile reflux, is closely related to poor gastric motility. The treatment focuses on suppressing stomach acid, protecting the gastric mucosa, and enhancing gastric motility. The treatment usually lasts for 6 to 8 weeks. Additionally, if erosion is found in the gastric mucosa, a biopsy, or pathological examination, is typically conducted to investigate the nature of the erosion under a microscope. If the erosion is inflammatory, it is considered mild. However, if atypical hyperplasia or intestinal metaplasia is present, there is a very small risk of cancer development. Therefore, if the biopsy results show atypical hyperplasia, it should be taken very seriously. In cases of severe atypical hyperplasia, it is recommended to perform a gastric mucosal stripping surgery under endoscopy.
