Chronic Cough Symptoms

A cough that lasts more than eight weeks is classified as a chronic cough. Although it may start as a simple irritation, a prolonged cough can signal underlying respiratory or systemic illness. Understanding its symptoms and possible causes helps ensure timely treatment.

How a Chronic Cough Develops

Coughing is a protective reflex that clears the airways. However, persistent irritation, from infection, allergies, reflux, or lung disease, can keep the cough reflex active long after the initial trigger has passed.

Major Symptoms Associated with Chronic Cough

Persistent Dry Cough: A non-productive cough without mucus is often seen in asthma, post-viral syndrome, or lung fibrosis.
Cough with Phlegm: When mucus accompanies coughing, it may indicate chronic bronchitis, COPD, or bacterial infection.
Shortness of Breath and Wheezing: Ongoing airway inflammation narrows breathing passages, causing wheezing sounds or breathlessness.
Chest Tightness or Pain: Continuous coughing strains chest muscles and may cause soreness.
Voice Changes and Throat Irritation: A prolonged cough can lead to hoarseness due to vocal-cord irritation.
Cough Worsening at Night: Common in asthma and acid reflux, as lying flat allows mucus or stomach acid to irritate the throat.

Common Causes

Respiratory infections that linger
Allergies and sinus issues are causing post-nasal drip
Asthma and COPD
Gastro-oesophageal reflux (GERD)
Smoking or exposure to pollution
Chronic lung conditions like fibrosis

When to See a Doctor

Seek medical evaluation if your cough lasts longer than eight weeks, produces blood, or is accompanied by fever, fatigue, or unexplained weight loss.

Diagnosis

Tests may include chest X-ray, lung function tests, allergy screening, and sometimes CT scans to identify underlying causes.

Conclusion

A chronic cough may seem harmless, but it often reflects deeper respiratory issues. Paying attention to accompanying symptoms of chronic cough and consulting a specialist early can lead to an accurate diagnosis and effective treatment, protecting long-term lung health.
