Laryngitis: Causes, Symptoms, Diagnosis, Treatment, and Prevention

Laryngitis is a common condition that affects the voice box (larynx). It occurs when the vocal cords become inflamed due to infection, overuse, or irritation. The main symptom is hoarseness of voice, but in severe cases, people may temporarily lose their voice completely. Laryngitis can affect anyone, from children to adults, and though it is often temporary, recurrent or chronic laryngitis may signal an underlying health issue.

What is Laryngitis?

The larynx, also known as the voice box, is located in the throat and plays a crucial role in breathing, speaking, and protecting the airway during swallowing. Inside the larynx are the vocal cords, which vibrate to produce sound.

When the vocal cords become inflamed or irritated, they swell. This swelling affects the way air passes through the larynx, resulting in a hoarse, weak, or lost voice. This condition is called laryngitis.

Types of Laryngitis

1. Acute Laryngitis

• Short-term condition
• Usually caused by infections like the common cold, flu, or vocal strain
• Lasts less than 2–3 weeks

2. Chronic Laryngitis

• Long-lasting inflammation of the larynx
• Symptoms last more than 3 weeks
• Often caused by smoking, acid reflux, allergies, or long-term vocal strain

Causes of Laryngitis

Laryngitis can occur due to various reasons. The most common causes include:

1. Viral Infections

• Most frequent cause of acute laryngitis
• Often linked to upper respiratory infections such as cold or flu

2. Bacterial Infections

• Less common than viral
• May cause more severe throat irritation

3. Fungal Infections

• Seen in people with weakened immunity
• Often linked to long-term use of inhaled corticosteroids

4. Overuse of Voice

• Excessive talking, shouting, or singing
• Common in teachers, singers, and public speakers

5. Irritants and Allergies

• Smoking, secondhand smoke, air pollution
• Chemical exposure, allergens, dust, or strong odors

6. Gastroesophageal Reflux Disease (GERD)

• Acid reflux irritates the vocal cords, leading to chronic laryngitis

7. Other Factors

• Excessive alcohol use
• Dehydration
• Sudden changes in temperature

Symptoms of Laryngitis

The symptoms of laryngitis may vary depending on whether it is acute or chronic. Common symptoms include:

• Hoarseness or raspy voice
• Weak or lost voice
• Sore throat
• Dry throat or tickling sensation
• Difficulty speaking
• Persistent cough
• Low-grade fever (sometimes)
• Swollen lymph nodes (in bacterial cases)
• In children, laryngitis may cause a condition known as croup, which leads to a barking cough and difficulty breathing.

Risk Factors for Laryngitis

Certain people are at higher risk of developing laryngitis, including:

• Teachers, singers, and speakers who strain their voices frequently
• Smokers and alcohol users
• People with allergies or asthma
• Individuals with GERD (acid reflux)
• Children under 5 years, who are prone to croup
• People with weakened immune systems

Complications of Laryngitis

Most cases of laryngitis are mild and temporary. However, untreated or chronic laryngitis can lead to:

• Persistent hoarseness
• Voice loss
• Vocal cord nodules or polyps
• Chronic sore throat
• Breathing difficulties (rare, but possible in croup or severe swelling)

Diagnosis of Laryngitis

A doctor usually diagnoses laryngitis based on medical history and physical examination. In some cases, additional tests may be required:

1. Laryngoscopy

• A thin tube with a camera is inserted into the throat to view vocal cords.

2. Voice Analysis

• Examines pitch, tone, and strength of voice.

3. Throat Culture or Lab Tests

• Helps detect bacterial or fungal infections.

4. Biopsy

• Rarely needed but may be done to rule out cancer or other chronic conditions.

Treatment of Laryngitis

1. Home Remedies and Self-Care

Most cases of acute laryngitis improve within a week with simple home care:

• Voice Rest – Avoid speaking or whispering too much
• Stay Hydrated – Drink warm fluids and plenty of water
• Steam Inhalation – Helps soothe the throat and reduce irritation
• Use a Humidifier – Keeps the air moist, preventing dryness
• Avoid Irritants – Quit smoking and avoid polluted air
• Warm Salt Water Gargle – Reduces throat inflammation
• Honey and Herbal Teas – Natural remedies to soothe the throat

2. Medical Treatment

If symptoms persist or worsen, medical treatment may be necessary:

• Pain Relievers – Acetaminophen or ibuprofen for pain and fever
• Antibiotics – Only if bacterial infection is confirmed (not useful for viral cases)
• Antifungal Medications – For fungal laryngitis
• Corticosteroids – Reduce inflammation in severe cases, especially for singers or public speakers
• Treatment for GERD – Antacids or proton pump inhibitors for reflux-related laryngitis

3. Surgical Treatment

• Rarely required, but may be considered if chronic laryngitis leads to polyps, nodules, or vocal cord damage.

Prevention of Laryngitis

• Prevention is always better than cure. To lower the risk of laryngitis:
• Avoid smoking and alcohol
• Stay hydrated with enough water daily
• Limit caffeine intake, as it dehydrates the body
• Use microphones if speaking in large gatherings to avoid strain
• Maintain good vocal hygiene by avoiding shouting or long talking without breaks
• Treat acid reflux promptly
• Wash hands regularly to prevent viral infections
• Avoid exposure to irritants such as dust, smoke, and chemicals

Laryngitis in Children

In children, laryngitis often presents as croup. Symptoms include:

• Barking cough
• Hoarse voice
• Stridor (noisy breathing)
• Breathing difficulties in severe cases
• Parents should seek immediate medical attention if a child has difficulty breathing, bluish skin, or persistent high fever.

Frequently Asked Questions (FAQs)

1. How long does laryngitis last?
   Acute laryngitis usually lasts 7–10 days, while chronic laryngitis can persist for weeks or months.
2. Can laryngitis cause permanent voice loss?
   Most cases are temporary, but untreated chronic laryngitis may cause long-term vocal cord damage.
3. Is laryngitis contagious?
   Viral laryngitis can be contagious, similar to a cold or flu, but non-infectious causes (like acid reflux or smoking) are not.
4. What foods should be avoided during laryngitis?
   Avoid spicy foods, caffeine, alcohol, and very cold drinks, as they irritate the throat.
5. Can singers get laryngitis more often?
   Yes, professional voice users like singers, teachers, and speakers are more prone to laryngitis due to vocal strain.
