Tears of the cardia mucosa are more serious. Cardia Mucosal Tear Syndrome is usually caused by a longitudinal tear that occurs after repeated vomiting, which causes mucosal damage and affects the supply of capillaries. In the early stages, patients may experience nausea and severe vomiting, or blood in the vomit, as well as tearing pain in the upper abdomen; in severe cases, patients may vomit blood and have black stools or even go into shock. Mild cases can heal on their own, and generally only need internal conservative treatment, mainly for blood volume supplementation and application of various hemostatic measures, including the application of acid-suppressing drugs such as omeprazole and magnesium alumina carbonate and other mucosal protective agents, endoscopic hemostasis or surgical treatment. In case of cardia mucosal tear, one should promptly consult the gastroenterology department or emergency department to seek professional physician’s treatment and make timely management to avoid more serious consequences.
