Cardia erosion is a condition in which there is a break in the mucosa found and clearly identified by electrogastroscopy, and the extent of damage is limited to the mucosal layer at the cardia. This condition is directly related to excessive gastrointestinal secretion, inattentive eating, and the presence of H. pylori infection. It is necessary to find out if there is H. pylori infection, and if this bacterial infection exists, it needs to be killed off using quadruple therapy, and then treated with drugs that inhibit gastric acid and promote healing of the cardia mucosa, the latter being commonly treated with omeprazole, lansoprazole plus rehabilitative new liquid. Cardia erosion may be directly related to eating too much, or eating too much greasy, hard-to-digest food, so it is important to control this condition in the diet. Because overeating and eating too much can cause reflux, food containing stomach acid going up can cause mucosal damage at the cardia, so the treatment is usually treated with the addition of mosapride citrate and domperidone anti-reflux treatment.
