Chronic cough and OSA: an underappreciated relationship
Lung
|November 16, 2013
Summary
Chronic cough may be triggered by obstructive sleep apnea (OSA). This review examines the clinical evidence and potential mechanisms linking these conditions.
Area of Science:
- Pulmonology
- Sleep Medicine
- Internal Medicine
Background:
- Chronic cough is a complex condition with various triggers.
- Obstructive sleep apnea (OSA) is a newly identified potential cause of chronic cough.
Purpose of the Study:
- To review the clinical evidence connecting obstructive sleep apnea and chronic cough.
- To explore the potential mechanisms underlying this relationship.
Main Methods:
- Literature review of existing clinical studies.
- Analysis of mechanistic pathways linking OSA and cough.
Main Results:
- Evidence suggests a link between obstructive sleep apnea and chronic cough.
- Potential mechanisms include upper airway irritation and reflux.
Conclusions:
- Obstructive sleep apnea is a plausible contributor to chronic cough.
- Further research is warranted to confirm the causal link and explore therapeutic implications.

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

4.0K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Chronic obstructive pulmonary disease is a common, preventable, and treatable respiratory disorder characterized by persistent symptoms and progressive airflow limitation. This limitation results from a combination of small-airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), both driven by chronic inflammation from exposure to harmful particles or gases.The disease includes two main pathological entities: emphysema, marked by destruction of alveolar walls and...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
