Feeling that there is gas in the chest blocking the throat is considered to be related to heart disease, lung disease and digestive disease. 1. Heart disease: For example, if the patient has coronary heart disease or cardiomyopathy, it may be due to an acute attack, which may cause myocardial ischemia, resulting in the symptom of tightness in the chest, which is like a gas blockage from the chest to the throat. 2. Lung disease: if the patient has lung disease, such as pneumonia, tuberculosis, lung cancer, etc., it may affect the ventilation function of the lungs, which will make the patient feel that there is a gas blockage in the chest to the throat. 3. Digestive diseases: If the patient has functional dyspepsia, it may also be reflux esophageal disease, or because the food accumulates in the intestines for a long time, and after being fermented by the bacteria, it will produce more gases, which will cause the symptom of feeling that there is a gas blocking the chest to the throat. Patients can go to the hospital for consultation and cooperate with the doctor to complete the relevant examinations to determine the cause before treatment and therapy.
