Vocal Cord Dysfunction (VCD) is a hidden, yet very, VERY common, usually unsuspected condition of throat closure &/or choking sensation that can strike any age, can cause sudden, severe episodes (attacks) of breathing difficulty, sometimes with wheezing (whistling or sighing sounds) &/or stridor (harsh, high pitched, ‘windy’ gasping sounds). In the Emergency Room (ER), VCD is usually misdiagnosed as being difficult (refractory, or brittle) asthma, anaphylaxis (severe, life threatening allergic reaction), or hysteria (all in one’s head).

VCD can feel like straining to breathe through a straw. Some cannot get any air in (or out) at all. Panic and fear of dying from feeling that one isn’t getting in enough air, often causes repeated ER visits or hospitalizations. 

The "throat" closure actually occurs inside the voice box (larynx), (behind the "Adam's apple") when the vocal cords go into a "closing-up" spasm.  (See drawing on web-page 1).

VCD attacks can happen at any time, including at night, while sleeping, or, at rest, when exercising, during or after meals, etc.

A VCD patient can have one, several, or even many causes of VCD.

Many doctors, nurses and ER personnel have not yet heard about VCD, even though VCD is common. Although there are many journal articles in the medical literature about VCD, few medical text books even mention VCD, even though VCD has probably existed since time immemorial --like from volcanoes, dust storms, forest fires, "silent" gastric reflux (without heartburn), other medical conditions, etc.

VCD was seen to exist, back in the 1800's (mistakenly called hysteria), was written about in medical literature in the 1970's, and later, VCD was studied extensively by Nat'l Jewish Medical & Research Center in Denver, CO in the 1980's to the present/2017. Much confusion existed and still does, from the many different names given to VCD, and from the multi-factorial (many possible causes) nature of VCD. 

Misdiagnosis of VCD as asthma--when the person doesn't have asthma at all--or, has only mild to moderate asthma-- has resulted in many VCD patients unnecessarily taking steroids &/or bronchodilators for years, and even decades, before finally getting correctly diagnosed with VCD.

Also, VCD attacks can happen alone, or along with, some life-threatening conditions. Some of these life-threatening conditions may have symptoms that "mimic" (seem similar to) VCD. Some examples are: severe asthma, severe allergic reactions (anaphylaxis), collapsed lung(s), pulmonary embolism, actual choking, something obstructing or narrowing parts of the airway, spasms of the diaphragm muscle, etc. 

And, (after the patient is saved by Emergency Room doctors), some of these life-threatening conditions, may even cause VCD attacks. One example of this, is pediatric gastric reflux. 

VCD attacks, themselves, can sometimes be life threatening (see webpage 2). And, please see NOTE!!! below:

DISCLAIMER: The information in this website is not intended to diagnose you. Call (911 or 0, etc.) for an ambulance, or go to an Emergency Room, IMMEDIATELY, for any breathing problems! Then, please see web-page 4, for "VCD Attack SURVIVAL GUIDE".

The information in this website comes from the experiences of many patients (some diagnosed with VCD/laryngospasms, and some not yet diagnosed), from doctors, (see below for descriptions of specialist doctors), nurses, speech pathologists, respiratory therapists, medical journal articles, books, VCD patients, VCD Conferences, etc.  As I learn more information, I add it to this website. 

After being seen in an Emergency Room, you may need to go to one or several types of doctors, speech pathologists, and others, to help you get FULLY and ACCURATELY diagnosed: your primary care doctor, a Pulmonologist (Lung specialist doctor), an ENT (Ear, Nose & Throat specialist doctor, especially a LARYNGOLOGIST-- who specializes in Voice, vocal cord, throat problems, etc.), a Gastroenterologist (Digestive specialist doctor), an Allergist (Allergy specialist doctor), a doctor who is a specialist in Environmental & Occupational Health, a Neurologist (Nerves & brain specialist doctor), an Endocrinologist for thyroid problems, hormone imbalances, etc., a Respiratory Therapist, a SLP (speech & language pathologist), Gynecologist (for possible female problems), Urologist (for possible male problems), a Cardiologist (heart doctor), an Anesthesiologist (to prevent a "laryngospasm" during or right after an operation/surgery), &/or other kinds of specialists (doctors, etc.). 

This may include speaking with each doctor, etc., getting examined (including by an ENT doctor and speech pathologist, directly looking at vocal cords, during a "laryngoscopy" exam), having medical tests done &/or prescribed, and learning about treatment choices (options), etc., described by each doctor, etc.

It was not easy for my husband and me to get the VCD correctly diagnosed: 

In 1998, my husband went to several Emergency Rooms, where no doctor had any idea of what he really had. He was misdiagnosed as possibly having asthma, or midlife crisis, or panic attacks. Finally, after about a week of very frequent VCD attacks, a Pulmonologist (lung specialist doctor) suspected VCD, and recommended that my husband go to National Jewish Medical & Research Center, in Denver, Colorado (see webpage 7), where he was quickly diagnosed with VCD, that same day, in 1998. 

A Speech/Language Pathologist (SLP) at Nat'l Jewish taught him how to do the special speech therapy (see webpage 4) that stops most VCD attacks, the same day he was diagnosed, and he was told to work on improving his sinus condition. Then, we began the tedious but necessary work of figuring out all (or most of) my husband’s underlying causes of his VCD. 

Doing this helped me to discover the SINUS TIPS, and the GASTRIC REFLUX TIPS, (see Appendix A & B, on webpage 10), which resulted in my husband quickly conquering his VCD, in 1998. He has had no more VCD attacks, since that year (1998), including up to now (2017), which means about 19 years of being free from VCD attacks.

In 2000, I first had VCD attacks (during a severe case of bronchitis). After many misdiagnoses at Emergency Rooms, I also went to Nat’l Jewish, and was quickly diagnosed with VCD. VCD is not “catching”, but, it is common. Each person’s list of VCD causes is unique to that person. Using the SINUS TIPS, and the GASTRIC REFLUX TIPS, helped me to also quickly control my VCD, back in 2000.

After we both learned how to immediately stop any VCD attack, I created this free VCD website, in 2001, to help others of all ages, whose VCD hasn’t yet been diagnosed. No one should suffer one minute longer than necessary, with this frightening and sometimes dangerous ailment.

My husband, who had "exercise-related" VCD, and also VCD at rest, has had no more VCD attacks for about 19 years, 

I now (2017) have almost no more VCD attacks, except for the very rare VCD attack due to swallowing something, such as saliva, or food, or liquid, "the wrong way", causing normal "choking", that leads to a VCD attack, or, from "burping" (gas or liquid) due to an episode of gastric reflux.


I receive no financial help, and I continue to research and update the website, myself. 

If you would like to speak by phone, or send me an email, I would be happy to try to help you or whoever has the VCD, to conquer it, as quickly and as easily as possible. 

Donations are not required. If you can afford to, and if you want to, I appreciate any donation, to help me be able to spend time helping VCD patients, and, for updating the website. 

Although I am not a medical doctor (MD), I am a former RN/registered nurse, with many years of experience dealing holistically with various ailments, including conquering my husband's and my previous VCD attacks (and helping many, many others to conquer their VCD). The advice I can give you, is not medical advice--it is practical advice. The practical advice can help you to make a plan, about what you can try doing (and not doing), and also includes seeing various VCD-knowledgable specialist doctors, to be safe, and to get fully and accurately diagnosed, and correctly treated for your specific situation.
