The repair time of gastric mucosal damage usually takes 1-2 months, which cannot be generalized and needs to be judged based on various factors such as the degree of mucosal damage and personal constitution of the patient. In case of mild gastric mucosal injury, it may lead to gastric mucosal congestion, erosion, edema, and in serious cases, gastric mucosal ulcer, bleeding, or even gastric perforation may occur. If the patient is in good health, his condition is mild and he pays attention to adjusting his diet, he can generally recover in about 1-2 months. However, if the patient is in poor physical condition and the condition is severe, the recovery time will be prolonged or even prolonged. After the occurrence of gastric mucosal damage, it is recommended to eat a light, nutritious and regular diet, avoid eating foods that are too hot and irritating, and if necessary, cooperate with medication under the guidance of a doctor to promote the repair of the gastric mucosa.
