Chronic Cough: What's Behind That Nagging Hack?
Published: Jun 04, 2024
Chronic cough is more than just an annoyance. It's a symptom that affects up to 12% of the population and can indicate a variety of underlying health issues.
Understanding Chronic Cough
Chronic cough is a cough lasting more than eight weeks. It can be caused by conditions such as asthma, gastroesophageal reflux disease (GERD), or even medications like ACE inhibitors. Women are more likely to suffer from chronic cough than men, possibly due to heightened reflex sensitivity.
Common Triggers and Causes
Among the myriad causes, asthma and GERD are prevalent. Asthma-related coughs are often accompanied by wheezing and shortness of breath, whereas GERD-related coughs may occur without the typical heartburn symptoms. Postnasal drip, a result of upper airway cough syndrome, is another frequent cause.
The Role of the Cough Reflex Arc
The cough reflex arc involves complex signaling between the cough receptors and the brain's cough center. This reflex can become hypersensitive, making even mild irritants trigger a cough.
