Clinical Overview & Pathophysiology
Asthma often starts with subtle signs. [Featured Snippet: The early warning signs of asthma include a persistent dry cough (especially at night or after exercise), frequent throat clearing, shortness of breath on mild exertion, and a slight whistling sound during exhalation.] Recognizing these early signs can prevent severe attacks.
Key Clinical Facts & Indicators
- Persistent Night Cough: A dry, hacking cough that wakes you up between 1 AM and 4 AM.
- Whistling Exhalation: A faint squeaking or whistling sound when breathing out.
- Rapid Exertional Fatigue: Getting tired or out of breath faster than usual during normal play or walking.
- Chest Tightness: Sensation of a band tightening around the chest, making deep breaths difficult.

Frequently Asked Questions
Q: Can asthma start with only a cough?Yes, this is known as cough-variant asthma, where a dry cough is the primary symptom without noticeable wheezing.
Q: Is a chest X-ray enough to diagnose asthma?A chest X-ray helps rule out infections, but a spirometry (lung function) test is required to confirm asthma.
