It’s often a combination — here’s how they can overlap:

Condition What It Might Do
Aspergillosis (e.g. ABPA or Aspergillus bronchitis) Causes thick, sticky mucus with fungal elements and inflammation. Often leads to coughing up plugs or brown mucus.
Asthma Can increase mucus production, especially if poorly controlled or if triggered by allergens (including Aspergillus).
Both together May cause ongoing mucus, irritation, and airway narrowing that makes it harder to clear, despite constant coughing.

If you’re seeing more mucus than usual, it could mean:

  • A flare-up of fungal activity

  • A reaction to something environmental (e.g. pollen, dust, damp)

  • Or simply a bad asthma spell with more inflammation


🧼 The ‘Bottle Brush’ Analogy

An image of wanting to “scrub” the airways is very real — many describe the feeling of:

  • Something stuck that won’t budge

  • Needing a deep clean they can’t reach with coughing

  • Wishing there were tools to physically clear the airways


What You Can Try to Help Clear the Mucus

Here are real methods people find helpful (with advice from a respiratory physio):

  1. Airway Clearance Devices (like a ‘brush’ for your lungs!):

    • Flutter or Acapella devices: use vibration and pressure to loosen mucus

    • Positive Expiratory Pressure (PEP) therapy: helps open and clear airways
      (You can ask your team for one, or see if your hospital physio provides them.)

  2. Breathing & Huff Coughing Techniques:

    • Controlled deep breaths, then a huff (a strong open-mouthed exhale like steaming up a mirror) instead of hacking coughs

    • This moves mucus from deep down to the top of the lungs where it’s easier to shift

  3. Positioning/Gravity Drainage (Postural Drainage):

    • Certain positions help drain mucus from different lobes of the lungs — especially useful for bronchiectasis or ABPA.

  4. Steam with Caution:

    • Mild steam inhalation (e.g. from a shower) can loosen secretions — just avoid essential oils or herbs if you’re sensitive.

  5. Hydration and Mucolytics:

    • Staying hydrated helps thin the mucus.

    • Some are prescribed carbocisteine to reduce mucus stickiness.

  6. Speak to your team if:

    • The mucus is changing in colour or amount

    • You feel more breathless

    • You’re unsure if it’s a fungal flare or asthma spike

They might check for infection, offer a sputum test, or tweak your medication.


🗣️ Patient Voices

“I felt like I had cobwebs or glue in my lungs. The flutter device gave me back a sense of control — I still have to work at it, but I don’t feel as helpless.”

“When I learned to huff cough and did it properly, I was amazed at how much came up. It’s not a miracle, but it made me feel cleaner inside.”
