Bronchial asthma, commonly referred to as asthma, often results in symptoms such as wheezing, shortness of breath, chest tightness, and coughing in patients. However, these symptoms do not always appear simultaneously in an individual. It's possible for a single symptom to serve as the initial manifestation of bronchial asthma. For example, the condition may present solely as wheezing, chest tightness, or, notably, as coughing, where it is the only symptom. The characteristics of asthma-related coughing primarily include a certain rhythmic pattern, typically worsening during early morning or late night, and it can easily lead to coughing up blood. Additionally, the coughing may begin and end abruptly and can be triggered by exposure to cold air or strange smells, followed by spontaneous improvement after a period. These are distinctive features of bronchial asthma coughing.
