Hoarseness: Causes, Diagnosis & Prevention

Hoarseness is a condition where your voice sounds breathy, raspy, or strained, often resulting from issues in the vocal folds of the larynx. Understanding the causes of hoarseness, its symptoms, and methods for diagnosis can help in managing the condition effectively. Treatments range from voice rest to medical intervention, while preventative measures like avoiding vocal strain and staying hydrated play a key role in maintaining vocal health.

Overview – What is Hoarseness and How Does Your Voice Work

The process of voice production begins in the larynx, located between the base of the tongue and the top of the trachea. When you speak, the vocal folds come together, and air from the lungs causes them to vibrate, producing sound. The pitch, tone, and volume of your voice depend on the size and tension of the vocal folds, as well as the shape of the resonating cavities in your throat, nose, and mouth.

Hoarseness occurs when the normal function of the vocal folds in the larynx is disrupted. This disruption can change the way the vocal folds come together and vibrate, affecting the quality of the sound they produce.

This is when your voice undergoes noticeable changes, becoming breathy, raspy, or strained. It may also result in a lower pitch or reduced volume. This happens when the vocal folds in the larynx, which vibrate to produce sound, are affected.

Symptoms of Hoarseness

• Breathiness or raspiness in voice
• Difficulty projecting or maintaining a normal speaking tone
• Scratchy or strained throat
• Reduced vocal strength or sudden loss of voice

Persistent hoarseness, lasting more than three weeks, could be indicative of underlying health issues and warrants medical attention.

Disorders That Cause Hoarseness

Several conditions and habits can lead to hoarseness, including:

1. Laryngitis

Temporary swelling of the vocal folds due to infections, colds, or allergies is a common cause of hoarseness. Rest and hydration usually help resolve the condition.

2. Misusing or Overusing Your Voice

Yelling, speaking or singing for extended periods without rest can strain the vocal folds, leading to dysphonia, which is a condition characterised by voice disorders.

3. Gastroesophageal Reflux (GERD)

Stomach acid rising to the throat can irritate the larynx and vocal folds, causing hoarseness, particularly in the morning.

4. Vocal Nodules, Polyps, and Cysts

These benign growths can develop on the vocal folds due to prolonged vocal strain or other irritants.

5. Vocal Fold Haemorrhage

A sudden rupture of blood vessels in the vocal folds, often caused by excessive vocal exertion, can lead to immediate and severe hoarseness.

6. Neurological Disorders

Conditions such as Parkinson’s disease or spasmodic dysphonia (a rare neurological disorder affecting vocal muscles) can interfere with normal voice production.

7. Other Causes

• Injuries to the larynx
• Thyroid problems
• Laryngeal cancer
• Recurrent respiratory papillomatosis (non cancerous tumours in the larynx)

Hoarseness Diagnosis

Diagnosing hoarseness typically involves the following steps:

1. Medical History and Symptom Discussion
   Your doctor will ask about the duration of your hoarseness and any associated symptoms, such as difficulty swallowing or breathing.
2. Physical Examination
   A thorough evaluation of the throat and neck is conducted to identify visible abnormalities.
3. Endoscopic Examination
   An otolaryngologist may use an endoscope (a thin, flexible tube with a light) to view the vocal folds closely.
4. Special Tests
   In some cases, additional tests like laryngeal stroboscopy (to analyse vocal fold vibrations) or imaging studies (to rule out structural abnormalities) are recommended.

Hoarseness Treatment and Management

The treatment for hoarseness varies based on its underlying cause. Here are some common approaches:

1. Rest and Hydration

Allowing the vocal folds to recover by resting your voice and staying hydrated is often sufficient for mild cases.

2. Voice Therapy

For individuals who overuse their voices, such as singers or teachers, speech-language pathologists can provide exercises to improve vocal techniques and reduce strain.

3. Medications

• For GERD: Antacids or proton pump inhibitors
• For Allergies or Infections: Antihistamines or antibiotics as needed

4. Surgical Interventions

In cases involving nodules, polyps, or cysts, surgery may be required to remove the growths.

5. Neurological Treatments

For conditions like spasmodic dysphonia, Botox injections or specific therapies may help manage symptoms.

How to Prevent Hoarseness?

• Stay Hydrated: Drink plenty of water to keep your vocal folds lubricated.
• Avoid Vocal Strain: Speak at a comfortable volume and pitch, avoiding yelling or whispering excessively.
• Quit Smoking: Smoking irritates the vocal folds and increases the risk of hoarseness and throat-related disorders.
• Manage Reflux: Follow a GERD-friendly diet and avoid late-night meals.
• Practice Vocal Warm-ups: Engage in warm-up exercises if your profession requires frequent voice use.
• Rest Your Voice: Give your vocal cords regular breaks, especially after prolonged speaking or singing.

When to See a Doctor?

If you’ve been hoarse for more than three weeks, especially without any associated cold or flu, it’s time to consult a doctor. Other signs that necessitate medical attention include:

• Persistent or severe throat pain
• Difficulty swallowing or breathing
• Coughing up blood
• A lump in the neck
• Complete voice loss lasting several days

1. Vocal Strain: Excessive talking, yelling, or singing.
2. Infections: Viral or bacterial infections like the common cold or laryngitis.
3. Acid Reflux: Stomach acid irritating the vocal cords (GERD).
4. Smoking: Damages the vocal cords over time.
5. Allergies: Can lead to throat irritation and swelling.
6. Nodules or Polyps: Growths on the vocal cords due to chronic strain.
7. Underlying Conditions: Such as thyroid issues or neurological disorders.

How to stop hoarse voice?

To relieve hoarseness, follow these tips:

1. Rest Your Voice: Avoid talking or whispering excessively to give your vocal cords a break.
2. Stay Hydrated: Drink plenty of water to keep your throat moist.
3. Use a Humidifier: Adding moisture to the air can soothe your throat.

6. Gargle with Salt Water: Reduces inflammation and clears mucus.
7. Over-the-Counter Remedies: Lozenges or throat sprays can provide temporary relief

What is the best medicine for hoarse voice?

The best treatment depends on the cause:

1. For Infections: Over-the-counter pain relievers like ibuprofen or acetaminophen can reduce discomfort.
