Generally, mild intestinalization cannot recover on its own. Intestinal chemosis is intestinal epithelial metaplasia, also clinically known as intestinal metaplasia, which refers to the replacement of normal gastric mucosal epithelial cells by intestinal epithelial mucosal cells, and is an anisotropic lesion, suggesting that it may be a precancerous lesion of gastric cancer. Intestinal metaplasia is also divided into small intestinal metaplasia and colonic metaplasia. Small intestinal metaplasia is mostly seen in benign lesions of the stomach, while a large proportion of colonic metaplasia will be transformed into cancer. The aggravation of the disease can be avoided by the following aspects: 1. diet: try to eat lightly, avoid stimulating food, quit smoking, alcohol, and do not drink strong tea and coffee; 2. lifestyle: maintain good habits, adequate sleep, good mentality, and through proper exercise, you can strengthen your body and speed up the repair of gastric mucosal epithelial cells, thus controlling the development of the disease. Pay attention to warmth, avoid cold stimulation, regular review, and take early treatment measures if abnormalities are found; 3. medication: drugs such as teprenone can be used as prescribed by the doctor to protect the gastric mucosa, and can also promote the metabolism of gastric mucosal cells, thus improving the symptoms.
