Stomach pain can be a sign of a bad heart or a disease of the stomach itself. Some heart diseases, such as unstable angina, acute myocardial infarction, etc., can be manifested as pain in the anterior region of the heart, but due to the proximity of the stomach to the location of the heart and the atypical location of the pain in some patients, the pain in the heart can be misinterpreted as the pain in the stomach, and then the cardiac disease is not treated in a timely manner. So stomach pain may also be a sign of a bad heart. However, stomach pain may also be a disease of the stomach itself, such as gastric ulcer, gastritis, etc., mostly accompanied by loss of appetite, nausea, abdominal pain and bloating and other symptoms. It is necessary to improve the relevant examination to clarify, such as electronic gastroscopy. Therefore, the occurrence of stomach pain is recommended to consult a doctor in time, improve the examination, clarify the cause of the disease, and be diagnosed and treated by a professional doctor.
