Patients with heartburn symptoms are advised to register with the gastroenterology department because most heartburn symptoms are caused by GERD, and patients often also exhibit acid reflux, regurgitation, regurgitation, abdominal pain, abdominal distention, and other atypical symptoms such as coughing, chest tightness, chest pain, and shortness of breath. However, when heartburn is present, it is also important to rule out the presence of heart disease, such as myocardial infarction. The gastroenterologist will routinely give an electrocardiogram screening, and if necessary, further cardiac enzyme profiles, etc. Only after cardiac disease is completely ruled out can electronic gastroscopy be completed, and only through electronic gastroscopy can the presence of GERD be clearly understood. If the heartburn is indeed caused by GERD, it needs to be treated with regular medication in cooperation with a specialist.
