Gastric mucosa can be repaired on its own and has a strong regenerative ability, but if too much gastric acid is secreted or lasts for a long period of time, it will affect the repair of gastric mucosa. Gastric mucosa refers to a layer of mucous membrane inside the stomach wall, which has a certain protective effect on the stomach wall and can prevent the attack of gastric acid. When gastric acid is secreted excessively, it will destroy the gastric mucosa. However, due to its strong repair and regeneration ability, it can be repaired on its own after damage occurs. However, if the gastric acid secretion is excessive or lasts for a long time without effective control, it will affect the repair of the gastric mucosa, resulting in incomplete repair. Patients with stomach discomfort are advised to go to the hospital in time to improve the examination and carry out standardized treatment under the guidance of the doctor to avoid delaying the condition.
