It should be chronic superficial gastritis with intestinalization, which belongs to the precancerous lesions of gastric cancer and can be relieved by regular acid suppression, protection of gastric mucosa and eradication of Helicobacter pylori. Chronic superficial gastritis with intestinalization refers to the gastric mucosal epithelium evolving into intestinal epithelium. This condition is a precancerous lesion of gastric cancer, suggesting an increased probability of gastric cancer. After regular treatment with acid suppression such as omeprazole, protection of gastric mucosa such as aluminum sulfate, and eradication of Helicobacter pylori such as quadruple regimen, most of the intestinal transformation may be reversed, but some patients may also have progression to gastric cancer. Note that the above drugs should be used under the guidance of a doctor, avoid unauthorized use of drugs to avoid adverse effects. If chronic superficial gastritis with intestinal metaplasia is found during examination, it is recommended to seek medical treatment in time and perform gastroscopy on a regular basis, and at the same time, standardize the diagnosis and treatment to avoid leading to the occurrence of gastric cancer.
