Overview

Laryngitis is the inflammation of your voice box (larynx) causing hoarseness or a total loss of voice. It is most often caused by a temporary viral infection or vocal strain and typically resolves within a week or two.

Understand this condition

The larynx contains your vocal cords, which are two folds of mucous membrane covering muscle. Normally, these cords open and close smoothly, creating sound through vibration. When inflamed, the cords swell and can no longer vibrate properly, leading to hoarseness.

Why it happens

Inflammation is often triggered by a viral infection that invades the upper respiratory tract. This causes the body to send immune cells to the throat, resulting in swelling and mucus production. Over time, physical strain or chemical irritants can also lead to long-term tissue changes.

Real-world scenarios

  • People may notice their voice crackling after a weekend of cheering.
  • This often appears as a lingering cough following a head cold.
  • People may notice a persistent raspiness that worsens at the end of the day.
  • This often appears as a tickle in the throat that prompts constant clearing.

Common vs serious explanations

Common
  • Recent recovery from a viral upper respiratory infection
  • Overusing your voice at a concert or sports event
  • Short-term irritation from seasonal allergies
  • Dry air in the home during winter months
Serious
  • Vocal cord nodules or polyps caused by long-term strain
  • Laryngeal cancer or other tumors in the throat area
  • Paralysis of the vocal cords from nerve damage
  • Epiglottitis, a life-threatening inflammation of the windpipe lid
  • Severe allergic reactions causing airway swelling

Causes

  • Viral infections (common cold or flu)
  • Vocal strain from yelling or overuse
  • Acid reflux (GERD)
  • Irritants like smoke or allergens

Risk factors

  • Recent respiratory infection
  • Smoking or exposure to secondhand smoke
  • Excessive talking, shouting, or singing

How it progresses

3 stages
  1. Onset
    Symptoms appear, often triggered by a known cause.
    Often missed
  2. Active phase
    Symptoms peak; self-care or short treatment usually helps.
  3. Resolution
    Symptoms ease over days to weeks with proper care.

How it's diagnosed

  • Physical exam of the throat
  • Review of vocal history
  • Laryngoscopy (viewing the voice box)

Treatment options

General educational information only — no dosage advice. Always follow guidance from a qualified clinician.

Medical
  • Treating underlying causes (like reflux)
  • Pain relievers (acetaminophen or ibuprofen)
  • Corticosteroids (in severe or professional cases)
Home care
  • Resting the voice (avoiding whispering)
  • Staying hydrated with fluids
  • Using a humidifier
  • Gargling with warm salt water
  • Voice rest

Complications

  • Breathing difficulty
  • Spread to airway
  • Dehydration
  • Recurrence of laryngitis

Prevention

  • Maintain a healthy lifestyle
  • See a clinician for routine check-ups

When to seek help

Urgent — same-day care
  • Symptoms persist beyond a few days
  • Symptoms interfere with daily activities
  • New or worsening symptoms appear
  • Concerning changes related to laryngitis
🚨 Emergency — call now
  • Difficulty breathing
  • Drooling or inability to swallow
  • Coughing up blood
  • High fever that won't go down

In any emergency, call your local emergency number or go to the nearest emergency department.
