Clinically, there are many possible causes of cough and a bitter taste in the mouth. The main consideration is symptoms arising from respiratory-related diseases. We need to take underlying medical conditions into account. For example, acute laryngitis or chronic pharyngitis may cause throat discomfort and coughing, and can also be accompanied by a bitter taste in the mouth. Gastroesophageal reflux disease (GERD) is another common cause; when stomach acid refluxes into the esophagus, it can not only trigger coughing but also lead to a bitter taste due to the acidic regurgitation. In addition, acute bronchitis or other respiratory tract infections may cause a bitter taste during coughing due to inflammation and the presence of sputum. A bitter taste in the mouth during coughing may result from various factors, so we need to comprehensively evaluate the potential causes and take appropriate measures to relieve the symptoms.
