Intestinal chemosis is the appearance of cells of the intestinal tract in the stomach wall. Many people usually do not pay attention to the diet, often eat spicy and irritating food, and bad eating habits can lead to superficial gastritis in the stomach. Long-term stimulation of the site of gastritis, the mucosa of the stomach gradually degenerates, leading to the appearance of the tissue of intestinal mucositis, while the function also gradually degenerates, so that intestinal chemosis is formed. This condition should be taken seriously, otherwise it is prone to cancer. It should be reviewed regularly at the hospital and surgical treatment should be performed in time once the trend of cancer appears to prevent the development of gastric disease into a malignant lesion. If the examination in hospital is mild intestinal metaplasia, cancer will not occur in general. However, extra attention should be paid to diet, try to eat more easily digestible and softer food, abstain from smoking and alcohol, avoid spicy and stimulating food, and go to hospital for regular review.
