Which condition is commonly associated with chronic cough?

Chronic cough can be a symptom of multiple underlying conditions, and both asthma and gastroesophageal reflux disease (GERD) are well-documented causes.

Asthma leads to chronic cough primarily due to airway inflammation and hyperreactivity, which can trigger coughing, especially at night or in response to certain stimuli like allergens or cold air. Persistent cough is one of the hallmark symptoms of asthma, and it may even be the only symptom in some individuals.

On the other hand, GERD causes a chronic cough through the mechanism of acid reflux irritating the throat and airways. This irritation can trigger a cough reflex, especially in individuals who experience nighttime reflux or regurgitation. The cough may also be associated with other GERD symptoms, such as heartburn or a sour taste in the mouth.

Since both conditions are frequently linked with chronic cough, the choice that includes both asthma and GERD as potential causes accurately reflects their association with this symptom. Recognizing that chronic cough can originate from various conditions is vital in clinical practice to provide effective and targeted treatments.
