Have you ever woken up in the middle of the night with a sudden sensation that you can't breathe? Have you experienced that distressing perception that something is blocking your throat, accompanied by a strange noise when trying to take in air? If your answer is yes, you may have experienced a glottic spasm, a medical condition that, although alarming, has an explanation and treatment.

As a specialist in digestive medicine with experience in managing pathologies that affect the upper airway, I want to explain clearly what exactly this condition is, why it occurs, and most importantly, what you can do about it.

What is Glottic Spasm Exactly?

Glottic spasm is an involuntary and sudden contraction of the muscles surrounding the vocal cords, located in the larynx. This contraction causes a temporary closure of the upper airway, generating that terrible sensation of asphyxiation that concerns you so much.

During an episode, the laryngeal muscles contract uncontrollably, creating a transient obstruction that prevents normal air passage to the lungs. It's as if someone momentarily squeezed your throat from the inside, unexpectedly blocking airflow.

The Causes Behind the Spasm: More Common Than You Think

Current scientific research has identified multiple factors that can trigger these episodes. As a specialist physician, I have observed that the most frequent causes in my practice include:

Gastroesophageal Reflux: The Most Common Culprit

Gastroesophageal reflux (GERD) represents one of the main causes of nocturnal glottic spasm. When stomach acid rises to the larynx during sleep, it irritates the sensitive tissues and can trigger a protective response in the form of muscle spasm.

Recent neurophysiological studies have demonstrated that in a significant proportion of patients with glottic spasm, GERD is an objective trigger, and its adequate treatment can considerably improve symptoms [Altemir et al., 2024].

Neurological Alterations

Laryngeal neuropathy and hyperexcitability of the superior laryngeal nerve also play a fundamental role in the pathophysiology of glottic spasm. These alterations can make laryngeal muscles react excessively to minimal stimuli [Sasaki & Suzuki, 1977].

Other Triggering Factors

We cannot forget other important causes such as:

• Respiratory infections: which increase laryngeal sensitivity
• Exposure to irritants: such as smoke, chemical vapors, or very cold air
• Psychogenic factors: stress and anxiety can contribute to the problem
• Medications: some drugs may increase susceptibility

Diagnosis: Key to Effective Treatment

As a physician, my diagnostic approach is always comprehensive. When a patient comes to my office with these symptoms, I perform a complete evaluation that includes:

Detailed Clinical History

It is essential to know the characteristics of the episodes: when they occur, what triggers them, their duration, and associated symptoms. I also investigate a history of gastroesophageal reflux, recent respiratory infections, and medication use.

Specialized Physical Examination

Otorhinolaryngological examination may reveal signs of laryngeal irritation or structural alterations that predispose to spasm.

Complementary Studies

In selected cases, specialized neurophysiological studies may be necessary to evaluate laryngeal nerve function and muscle response, especially when we suspect underlying laryngeal neuropathy.

Personalized Treatment: From Conservative to Specialized

The therapeutic approach to glottic spasm must be individualized, considering the underlying cause and symptom severity.

Conservative Strategies: First Line

For mild cases or when we don't identify a specific cause, conservative strategies have proven very effective:

Treatment of Gastroesophageal Reflux

When we document the presence of GERD as a triggering factor, the use of proton pump inhibitors (PPIs) is clearly indicated. In my clinical experience, adequate control of reflux usually translates to a notable improvement in spasm episodes.

Advanced Options for Refractory Cases

In situations where conservative measures are insufficient, we have more specialized treatments:

Botulinum toxin: For refractory cases or when there is evidence of laryngeal dystonia, electromyography-guided botulinum toxin injection represents the treatment of choice. Controlled trials have demonstrated its efficacy and safety [Sataloff et al., 2004]; [Hyodo et al., 2021].

Surgical interventions: In exceptional situations, such as laryngeal spasm secondary to neurovascular compression, microvascular decompression can be curative [Honey et al., 2019].

Practical Tips for Home Management

While we work on the underlying treatment, there are strategies that can help you during episodes:

When Should You Consult a Specialist?

As a physician, I recommend seeking specialized attention if:

• Episodes are frequent (more than once per week)
• Symptom intensity is severe
• You experience loss of consciousness during episodes
• Symptoms significantly interfere with your quality of life
• You suspect you might have associated gastroesophageal reflux

The Prognosis: Reasons for Optimism

It's important for you to know that glottic spasm, although distressing, has a good prognosis in most cases. With adequate diagnosis and personalized treatment, the vast majority of patients experience significant improvement in their symptoms.

Long-term follow-up studies show that conservative management combined with treatment of underlying causes achieves satisfactory symptomatic control in most cases [Pinder et al., 2007].

My Approach as a Specialist

In my daily clinical practice, I approach glottic spasm from a comprehensive perspective that considers not only the symptoms but also the impact on the patient's quality of life. My experience in advanced endoscopy and management of digestive pathologies allows me to identify and effectively treat cases related to gastroesophageal reflux.

Each patient is unique, and that's why I personalize treatment according to individual characteristics, always prioritizing the least invasive but most effective options.

Conclusion: Don't Suffer in Silence

Glottic spasm should not be a secret you keep out of fear or embarrassment. It is a real medical condition, with well-defined pathophysiological bases and effective therapeutic options.

If you experience these symptoms, I encourage you to seek specialized help. An accurate diagnosis and adequate treatment can restore your peace of mind for restful sleep without those terrifying nocturnal choking sensations.

Remember that current medicine offers us multiple tools to address this condition, from respiratory re-education techniques to specialized treatments when necessary. The important thing is not to normalize these episodes and seek the professional help you deserve.
