Generally celiac disease can be healed by taking medication for four weeks, but it needs to be treated differently according to the severity. Patients with mild erosion may not need medication, but should pay attention to their diet, rest, and maintain a good mood, which can be repaired in a short period of time by renewal and repair of the autologous gastric mucosa. In case of chronic persistent erosion, patients should take oral medication for treatment and almost all erosions can be treated after four weeks of oral intake. However, after healing, patients also have to pay attention to a regular diet, avoiding spicy and stimulating foods, smoking and alcohol, and avoiding foods such as coffee. It is important to pay attention to rest, patients should go to bed early and wake up early, and keep a happy mood. Medically, it should be noted that some celiac disease is a manifestation of early gastric cancer, which should be examined endoscopically by a professional doctor and determined whether it is early cancer. Early stage cancer can be completely removed and cured under endoscopy. Therefore, gastric erosion can be healed in about four weeks with medication. After healing, patients need to pay attention to diet, rest and keep a happy mood.
