Cough - Gaisou (English spelling) cough
Coughing refers to the phenomenon in which air from the lungs is reflexively expelled with a sound. It can be caused by various physical, chemical, or inflammatory stimuli of the upper respiratory tract. It can also be caused by irritation of the pleura, mediastinum, ears, esophagus, etc. The characteristics of coughs are diverse, and a wet cough is one that is accompanied by phlegm, while a dry cough is one that is not. The latter is mainly caused by extrapulmonary factors, while a wet cough occurs when there is secretion or exudate in the bronchi and lungs. The tone of the cough and the appearance of the attack vary depending on the illness. If a cough continues for 2 to 3 weeks, it may be a sign of a serious illness such as lung cancer, so it is necessary to consult a doctor.
