Chronic Cough

Chronic Cough

A chronic cough is a cough that persists for more than 8 weeks in adults (or more than 4 weeks in children). Unlike acute cough caused by common infections, chronic cough often indicates an underlying medical condition that needs evaluation.

Common Causes

• Post-nasal drip (Upper airway cough syndrome)
• Asthma (including cough-variant asthma)
• Gastroesophageal reflux disease (GERD)
• Chronic bronchitis (especially in smokers)
• Post-COVID lung disease
• Tuberculosis (TB)
• ACE inhibitor medications
• Allergies and environmental irritants

Symptoms Associated with Chronic Cough

• Persistent dry or productive cough
• Throat irritation or frequent throat clearing
• Breathlessness or wheezing
• Chest discomfort
• Heartburn or sour taste (in GERD)
• Nasal congestion or discharge

When to Seek Medical Attention 

Consult a doctor if you have:

• Cough lasting more than 3–8 weeks
• Blood in sputum
• Unexplained weight loss
