If you have aspergillosis, especially ABPA (Allergic Bronchopulmonary Aspergillosis) and bronchiectasis, it can be hard to know which one is flaring up when your lungs feel worse. They often overlap — but there are some clues that can help.


🔍 How the Two Conditions Are Different

Feature ABPA Flare (Allergic Reaction to Aspergillus) Bronchiectasis Flare (Infection in Damaged Airways)
Main cause Your immune system reacting to Aspergillus Infection in widened, inflamed airways
Symptoms you may notice – Chest tightness or wheezing
– Thick, sticky mucus
– Feeling more tired
– Occasional low-grade fever
– Wet cough with more sputum
– Sputum changes colour (green/yellow)
– Fever, chills, or general unwell feeling
How it starts May come on gradually or after exposure to damp/mould Often starts after a cold or virus
What helps most Steroids (inhaled or oral), sometimes biologics Antibiotics and chest physiotherapy
What tests may show – Raised IgE or eosinophils
– CT may show mucus plugs
– Raised CRP or white cells
– Sputum may grow bacteria or fungus
What to ask your doctor “Is my IgE or eosinophil count up?” “Do I need a sputum test or antibiotics?”

🧭 What Can You Do as a Patient?

  • 📝 Keep a symptom diary – especially note changes in:

    • Sputum colour or amount

    • Wheezing or chest tightness

    • Tiredness or sleep quality

  • 🧪 Ask for the right tests:

    • Blood tests like IgE and eosinophils for ABPA

    • CRP, white blood count, and sputum tests for bronchiectasis

  • 🩺 Don’t guess or self-treat – steroids and antibiotics work in different ways, and using the wrong one can make things worse or mask important signs.


💬 Final Thought

It’s very common for people with aspergillosis to feel confused by flare-ups — you’re not alone. Learning to spot your own patterns, and getting support from your specialist team, can make a real difference.
