🌬️ What is Asthma?
Asthma is a chronic (long-term) inflammatory disease of the airways that affects breathing. It causes the airways to become:
- Narrow
- Swollen
- Sensitive to triggers
This leads to recurring breathing problems.
🧠 Key Symptoms of Asthma
Symptoms can vary in severity and may come and go:
- Wheezing (whistling sound when breathing)
- Coughing (often worse at night or early morning)
- Shortness of breath
- Chest tightness or pressure
- Difficulty speaking during severe attacks
⚠️ Causes and Risk Factors
Asthma is caused by a combination of genetic and environmental factors:
🧬 Genetic factors
- Family history of asthma or allergies
🌍 Environmental factors
- Air pollution
- Tobacco smoke
- Respiratory infections
- Workplace irritants (occupational asthma)
- Allergens (pollen, dust mites, pet dander)
🎯 Common Triggers
Asthma symptoms can be triggered by:
- Cold air or sudden temperature changes
- Exercise (exercise-induced asthma)
- Strong emotions or stress
- Smoke or fumes
- Mold
- Viral infections
⏳ Long-Term Nature of Asthma
- Asthma is usually lifelong (chronic)
- Symptoms can improve with treatment but may return
- Some people become symptom-free with good management
- Without control, it may worsen over time
⚠️ Long-term effects if poorly controlled:
- Permanent airway narrowing (airway remodelling)
- Reduced lung function
- Increased risk of asthma attacks and emergencies
💊 Treatment and Management
Asthma cannot be cured, but it can be well controlled.
🟦 Controller treatment (daily)
- Prevents inflammation
- Reduces long-term symptoms
🟧 Reliever treatment (rescue inhaler)
- Used during attacks
- Quickly opens airways
🛠️ Additional management
- Avoid triggers
- Regular check-ups
- Allergy management (if relevant)
🚨 When to Seek Emergency Help
Seek urgent medical care if:
- Breathing becomes very difficult
- Rescue inhaler does not work
- You cannot speak in full sentences
- Lips or face turn blue/grey
🧩 Key Understanding
Asthma is:
- A long-term inflammatory condition
- Closely linked to allergies and immune system responses
- Manageable but potentially serious if untreated
🧠 Summary
✔ Chronic lung condition
✔ Causes breathing difficulties
✔ Triggered by environment + genetics
✔ Controlled with inhalers
✔ Requires long-term management
