🤔 What is Asthma?
Asthma is a chronic respiratory condition that affects the airways (bronchial tubes) in the lungs. The airways become inflamed, swollen, and narrow, making it difficult to breathe. Asthma causes episodes of wheezing, breathlessness, chest tightness, and coughing.
During an asthma attack, three main changes occur:
- Inflammation: The airway lining becomes swollen and irritated
- Bronchoconstriction: The muscles around the airways tighten
- Mucus Production: Excess mucus blocks the airways

Bronchodilator Test
Check improvement after medication
Allergy Testing
Identify potential allergens
Additional Tests
FeNO test, chest X-ray, CT scan
💊 Treatment Options
Asthma Action Plan
Personalized daily management plan
Controller Medications
Daily inhaled corticosteroids
Rescue Medications
Quick relief during attacks
Biologics
For severe asthma patients
Lifestyle Management
Trigger avoidance, exercise
