The pain in the heart that the patient is referring to is not caused by a real heart disease or lung disease, but by gas. The patient will feel pain in the heart after the gas reaches the upper part of the stomach, but after burping, the size of the stomach will decrease, so the gas will not reach the upper part of the stomach and the pain in the heart will be relieved. Therefore, patients need to rule out digestive system diseases such as chronic gastritis or peptic ulcer first. Patients can choose to go to the hospital to do gastroscopy to further confirm the diagnosis, and after the diagnosis can be treated symptomatically by oral medication, such as morpholine or omeprazole, with dietary attention, can achieve good results.
