Intestinal metaplasia refers to intestinal epithelial metaplasia, which is commonly found in chronic atrophic gastritis, but there is no clear study specifying the cancer rate of intestinal metaplasia, and as long as it is actively treated, there are more cases that do not become cancerous in a lifetime. If not treated, it may worsen or even become cancerous with age and development of the disease, but it takes a certain process, usually ranging from several years to decades, and the time will be shortened accordingly if there are poor daily diet and living habits. However, with early diagnosis and treatment, it is possible to reduce the chance of cancer, and even possible to cure, and in this case, it can last a lifetime without developing into cancer. Therefore, after the discovery of intestinal chemosis, chronic gastritis should be actively treated. In terms of drug treatment, drugs such as aluminum thioglycollate and montelukast can be used to protect the gastric mucosa as prescribed by the doctor, antibiotics such as metronidazole and hydroxybenzyl penicillin can be used to control H. pylori infection, and drugs such as cimetidine, omeprazole and domperidone can be used to inhibit gastric acid secretion and reduce the stimulation of gastric mucosa. In addition, patients should ensure adequate rest and sleep during treatment, avoid staying up late, fatigue, mood swings, and avoid stimulation of the digestive system by spicy and stimulating diets. It is also necessary to quit smoking and alcohol to avoid affecting the therapeutic effect and aggravating the disease.
