Vocal Cord Dysfunction
Today, we're exploring vocal cord dysfunction (VCD) - a condition that mimics asthma but doesn't respond to typical treatments.
What Is Vocal Cord Dysfunction?
VCD occurs when vocal cords inappropriately close during breathing, especially when breathing in. Instead of opening wide to let air flow freely, they squeeze together when they should be relaxed.
Normal breathing: Vocal cords open during inspiration VCD: Vocal cords inappropriately constrict, creating breathing difficulty
Did You Know? VCD affects up to 3% of the population and is often misdiagnosed as asthma for months or years.
VCD vs. Asthma: Spot the Difference
Key VCD Clues:
Difficulty getting air IN (not out)
Harsh sound when breathing in (inspiratory stridor)
Voice changes during episodes
No response to rescue inhalers
Normal oxygen levels during episodes
Rapid onset and quick resolution
Asthma Patterns:
Difficulty breathing OUT
Responds to bronchodilator medications
May have low oxygen during attacks
"The telltale sign is when patients say they can't get air IN, especially with normal oxygen levels. That's when I start thinking VCD." - Emergency Medicine Physician
Who Gets VCD?
Common in:
Young females (especially teens and young adults)
Athletes, particularly endurance sports
People with high-stress jobs or perfectionist tendencies
Triggers:
Exercise or strong emotions
Strong odors or irritants
Respiratory infections
Cold air
Quick Diagnosis
Key Tests:
Laryngoscopy (looking at vocal cords during symptoms)
Exercise challenge tests
Voice evaluation
Clue: If rescue inhalers don't help your "asthma," ask about VCD testing.
Treatment: Retraining Your Vocal Cords
Primary Treatment: Speech Therapy
Breathing retraining techniques
Vocal cord relaxation exercises
Throat muscle tension release
Emergency Techniques
During an episode:
Stay calm - remind yourself this will pass
Try "sniffing" breaths (small breaths through nose)
Use pursed-lip breathing
Try panting like a dog (forces vocal cords open)
"Speech therapy for VCD isn't just about talking—it's retraining your entire breathing system." - Speech Therapist
Managing VCD Daily
Prevention:
Identify and avoid triggers when possible
Practice stress management
Stay hydrated
Treat underlying conditions like GERD
Exercise Tips:
Proper warm-up routines
Breathe through nose when possible
Use rescue breathing techniques as needed
The Good News
VCD is highly treatable! Most patients see significant improvement with proper diagnosis and speech therapy. Episodes typically become less frequent and severe over time.
Success factors:
Early accurate diagnosis
Consistent practice of breathing techniques
Managing underlying triggers
Wrap-Up Challenge
This week:
Practice diaphragmatic breathing for 5 minutes daily
Notice and reduce throat clearing habits
Try the "sniffing" breath technique when stressed
Disclaimer: VCD requires professional diagnosis and treatment. If you experience breathing difficulties, consult healthcare providers for proper evaluation.
