A persistent cough lasting more than 8 weeks is classified as chronic cough, and its potential causes are diverse. Common culprits include postnasal drip, asthma, gastroesophageal reflux, chronic obstructive pulmonary disease, and bronchiectasis. Additionally, factors such as medication side effects, interstitial lung disease, tumors, among others, may play a role. Specific treatment approaches are warranted for different etiologies. In essence, the origins of cough are multifaceted, and while cough suppressants often offer only partial relief, it is crucial to pinpoint the underlying cause and tailor treatment accordingly.
