Vejdals Cough – A Complete Guide

What is Vejdals cough?

Vejdals cough, also spelled Vejdal’s cough, is a descriptive term for a persistent, dry, and often “barking” cough that originates from irritation of the upper airway. The name comes from the Danish pulmonologist Dr. Niels Vejdal, who first characterized this cough pattern in the late 1970s while studying patients with chronic laryngeal irritation. Although the cough itself is not a disease, it serves as a clinical clue that something is irritating the trachea, larynx, or nearby structures.

In practice, Vejdals cough is typically non‑productive (produces little or no sputum) and may worsen at night, with temperature changes, or after exposure to certain irritants. Because it mimics the classic “croup” cough in children, many laypeople mistake it for an infection, when in fact the underlying trigger is often non‑infectious.

Common Causes

Several conditions can provoke a Vejdals‑type cough. Below are the most frequently encountered causes, grouped by category.

• Upper airway hyper‑reactivity – e.g., post‑viral laryngeal inflammation, early‑stage asthma.
• Gastro‑esophageal reflux disease (GERD) – stomach acid refluxes into the throat, irritating the larynx.
• Post‑nasal drip (allergic or non‑allergic rhinitis) – mucus drains onto the posterior throat.
• Environmental irritants – tobacco smoke, pollutants, strong fragrances, or occupational dust.
• Medication‑induced cough – especially angiotensin‑converting enzyme (ACE) inhibitors.
• Vocal cord dysfunction / paradoxical vocal fold movement – inappropriate closure of vocal cords during breathing.
• Upper respiratory infections (URIs) – viral infections that leave lingering airway inflammation.
• Chronic sinusitis – persistent sinus infection with mucus overflow.
• Thyroid enlargement or goiter – compresses the trachea and produces a cough.
• Rare causes – such as tracheal tumors, foreign bodies, or neuromuscular disease.

Associated Symptoms

Patients with a Vejdals cough often report other signs that help pinpoint the cause:

• Hoarseness or a “rough” voice
• Burning sensation in the throat (especially after meals – suggests GERD)
• Throat clearing, feeling of a “lump” in the throat (globus sensation)
• Nighttime cough that disturbs sleep
• Sore throat or mild sore muscles in the neck
• Runny nose or watery eyes (if allergic rhinitis is present)
• Wheezing or shortness of breath (possible concurrent asthma)
• Heartburn, regurgitation, or sour taste in the mouth
• History of recent upper‑respiratory infection

When to See a Doctor

Most Vejdals coughs are benign and improve with simple measures, but you should seek medical care if any of the following occur:

• cough persists longer than 8 weeks despite home treatment
• coughing is severe enough to cause vomiting, chest pain, or difficulty breathing
• you notice blood‑streaked sputum or unexplained weight loss
• hoarseness lasts more than two weeks or worsens
• you have a known heart condition, uncontrolled asthma, or immunosuppression
• you develop fever > 38 °C (100.4 °F) or chills, suggesting infection
• symptoms are accompanied by swelling of the neck, trouble swallowing, or a feeling of obstruction

Early evaluation can identify treatable causes (e.g., GERD, medication side‑effects) and prevent complications.

Diagnosis

Evaluation begins with a thorough history and physical exam, followed by targeted testing when needed.

History

• Duration, timing (day vs. night), and triggers of the cough
• Medication list – especially ACE inhibitors, beta‑blockers, or inhaled steroids
• Dietary habits, reflux symptoms, and alcohol use
• Exposure history – smoking, occupational dust, pets, mold
• Associated ENT symptoms – nasal congestion, post‑nasal drip, voice changes

Physical Examination

• Listen to lungs for wheezes, crackles, or stridor
• Examine the throat, vocal cords (indirect laryngoscopy), and neck for masses
• Check for signs of reflux (e.g., dental erosion) and allergic rhinitis

Diagnostic Tests

• Chest X‑ray – rules out pneumonia, tumors, or left‑sided heart failure.
• Spirometry with bronchoprovocation – assesses asthma or airway hyper‑reactivity.
• 24‑hour pH monitoring or empirical trial of proton‑pump inhibitors – evaluates GERD.
• Allergy testing (skin prick or serum IgE) – identifies allergic triggers.
• Laryngoscopy or videostroboscopy – visualizes vocal cord motion, inflammation, or lesions.
• CT scan of the neck/chest – reserved for suspicion of structural lesions or tumors.

Treatment Options

Treatment is aimed at the underlying cause while providing symptomatic relief.

Medical Therapies

• Proton‑pump inhibitors (PPIs) – for GERD‑related cough (e.g., omeprazole 20 mg daily for 8‑12 weeks). Reference: Mayo Clinic, 2023.
• H2‑blockers or antacids – may be used as adjuncts.
• Inhaled corticosteroids – for underlying asthma or eosinophilic airway inflammation.
• Short‑acting bronchodilators (albuterol) – provide quick relief if bronchospasm is present.
• ACE‑inhibitor substitution – switch to an ARB (e.g., losartan) if medication is the culprit.
• Antihistamines and nasal corticosteroids – for allergic rhinitis or post‑nasal drip.
• Speech‑language therapy – specialized exercises for vocal cord dysfunction.
• Low‑dose macrolide therapy – occasionally used for chronic, non‑infectious cough with inflammatory component (consult pulmonologist).

Home & Lifestyle Measures

• Stay hydrated – warm teas with honey can soothe the throat.
• Use a humidifier (ideally 30‑40 % humidity) to keep airway mucosa moist.
• Elevate the head of the bed 10‑15 cm to reduce nocturnal reflux.
• Avoid known irritants: smoking, strong perfumes, dust, and cold air.
• Eat smaller, non‑spicy meals; avoid eating within 2‑3 hours of bedtime.
• Practice good posture and diaphragmatic breathing to reduce laryngeal strain.
• Limit alcohol and caffeine, which can aggravate reflux.

Prevention Tips

While not all triggers are avoidable, the following steps can lower the likelihood of developing a Vejdals cough:

• Quit smoking and avoid second‑hand smoke.
• Maintain a healthy weight to reduce intra‑abdominal pressure that promotes reflux.
• Follow an anti‑reflux diet: reduce citrus, tomato, chocolate, mint, fatty foods, and carbonated drinks.
• Schedule regular dental check‑ups – dental erosion can be an early sign of chronic reflux.
• Use protective equipment (mask, goggles) if you work in dusty or chemical environments.
• Keep household humidity between 30‑50 % and clean air filters regularly.
• Stay up‑to‑date with vaccinations (influenza, COVID‑19) to reduce respiratory infections.
• Review medications annually with your physician, especially if you’re on ACE inhibitors.

Emergency Warning Signs

If any of the following occur, seek emergency medical care (call 911 or go to the nearest emergency department):

• Sudden inability to speak or swallow, or a feeling of choking.
• Severe shortness of breath or chest tightness that does not improve with rescue inhaler.
• Coughing up large amounts of blood or bright red sputum.
• High fever (≥ 39 °C / 102 °F) with worsening cough.
• Rapid heart rate (> 120 bpm) or low blood pressure (systolic < 90 mmHg) accompanying cough.
• Swelling of the lips, face, or tongue (possible allergic reaction).
