When Breathing Feels Impossible and No One Has Answers
You push yourself in practice, take a deep breath, and suddenly your airway feels like it's closing. Or maybe it happens during a stressful meeting, a run, or even at rest. You've been told it's anxiety, or asthma, or just something you need to manage. But nothing seems to fully explain what's happening to you.
Vocal cord dysfunction (VCD), also called Inducible Laryngeal Obstruction (ILO) or Exercise-Induced Laryngeal Obstruction (EILO), is a condition where the vocal cords close unexpectedly, instead of opening, during breathing. The result can feel terrifying: tightness in the throat, noisy breathing, a sense of choking, or the inability to catch your breath.
Because VCD and EILO mimic asthma so closely, they're frequently misdiagnosed or missed altogether. Some people may cycle through pulmonologists, allergists, and emergency rooms without ever getting a clear answer. If that sounds familiar, you're in the right place.
What Is Vocal Cord Dysfunction (VCD/EILO)?
Vocal cord dysfunction is an upper airway condition where the vocal folds behave paradoxically: they partially or fully close (laryngospasm) during inhalation, restricting airflow at the larynx. This is sometimes called paradoxical vocal fold motion (PVFM).
EILO (Exercise-Induced Laryngeal Obstruction) is a specific form that occurs during physical exertion, and is especially common in teenagers and young athletes. ILO is the broader diagnostic term used to capture all forms of the condition, regardless of trigger.
Triggers vary by person and can include exercise, strong odors, cold air, stress, acid reflux, or even eating. VCD is treatable, and with the right therapy, most people see meaningful improvement.
Expert VCD and EILO Therapy in Boise
Heather L. Robinson, MA, CCC-SLP, is a voice and upper airway specialist with over three decades of clinical experience, and VCD is squarely within her niche. At Idaho Face & Voice, treatment is evidence-based, trauma-informed, and tailored to the individual, whether you're a competitive athlete, a busy professional, or a teenager who can't get through gym class without an episode.
Treatment for VCD typically includes:
- Breathing retraining techniques to override the paradoxical closure response
- Laryngeal control exercises targeting the specific muscles involved
- Trigger identification and management strategies, so you can anticipate and interrupt episodes before they escalate
Heather also coordinates with your referring providers, including ENT, pulmonology, and allergy specialists, to make sure your full care team is aligned. Learn more about Heather's background and clinical approach.

What Life Looks Like After VCD Treatment
Reclaim Your Breath, Reclaim Your Life
Breathe with confidence again. Learn reliable techniques to stop an episode before it escalates, whether you're mid-sprint or mid-presentation.
Get off the asthma treadmill. Many patients reduce or eliminate unnecessary inhaler use once their VCD is properly identified and treated.
Return to the activities you love. For athletes especially, successful VCD therapy means getting back to training and competing without fear of the next episode.
Frequently Asked Questions About VCD and EILO
No. Although VCD and asthma share symptoms—including shortness of breath, chest tightness, and noisy breathing—they are different conditions. The key difference is where the airway narrowing occurs: asthma affects the lower airways in the lungs, while VCD affects the voice box (larynx). Because of this, some people with VCD are prescribed inhalers that provide little relief because the airway restriction is occurring above the lungs.
A person can have both asthma and VCD. In fact, about 1 in 4 people with asthma may also have VCD or another form of inducible laryngeal obstruction (ILO). If asthma treatments are not fully relieving symptoms, an evaluation for VCD/ILO may be helpful.
Yes. Speech-language pathologists (SLPs) are considered the primary treatment providers for VCD/ILO. Since these conditions involve the larynx and vocal fold movement during breathing, SLPs are uniquely trained to evaluate and treat them. Treatment typically includes breathing retraining, laryngeal control techniques, and strategies to manage triggers. Speech therapy is the first-line treatment for VCD/ILO, and many people experience substantial improvement—often without medication.
Every person is different, but many patients experience meaningful improvement in about 3–5 sessions. The goal of therapy is to help you understand your triggers, learn effective breathing strategies, and gain the skills to manage symptoms independently. Heather will discuss your expected treatment plan after your evaluation.
Yes. Video visits are available for patients across Idaho, making specialized VCD/ILO care accessible even if you live outside the Treasure Valley. In some cases, an in-person evaluation may be recommended, and Heather can help you decide which format is best for your needs.
Possibly. Exercise-induced laryngeal obstruction (EILO) is relatively common in teenagers and young athletes, especially those participating in high-intensity sports. Because EILO and exercise-induced asthma can cause similar symptoms, they are sometimes confused—or may occur together. If inhalers aren't providing relief, or if symptoms such as throat tightness, noisy breathing, or difficulty breathing in occur during exercise, an evaluation for EILO may be helpful.
An accurate diagnosis can help ensure your teen receives the right treatment and returns to sports with greater confidence.
Yes. Standard pulmonary testing may not always detect problems involving the upper airway or larynx, and even a direct view of the larynx or "scope" (laryngoscopy) may appear normal, despite the larynx not functioning normally. Exposure to smoke, chemicals, fumes, strong odors, or other airborne irritants can sometimes lead to ongoing symptoms such as cough, throat tightness, shortness of breath, voice changes, or sensitivity to smells. In some individuals, these exposures can contribute to VCD/ILO, chronic cough, voice changes, or laryngeal hypersensitivity.
A specialized evaluation may help identify the source of symptoms and guide treatment.
