Overview
Acute laryngitis is a temporary inflammation of the larynx (voice box) that typically lasts less than three weeks. It is commonly caused by viral infections, such as those that cause the common cold or flu, or by overuse of the voice (e.g., yelling, singing, or prolonged speaking).
The condition is usually self-limiting and resolves with rest and supportive care. However, it can be uncomfortable and disruptive, especially for those who rely on their voice for work or daily communication.
Symptoms
Common signs and symptoms of acute laryngitis include:
- Hoarseness or a weak voice
- Loss of voice (aphonia)
- Sore throat or a tickling sensation in the throat
- Dry cough that does not produce mucus
- Low-grade fever (if due to infection)
- Difficulty speaking or pain when speaking
- Throat irritation or a feeling of a lump in the throat
If symptoms persist for more than two weeks or are accompanied by severe pain, difficulty breathing, or high fever, seek medical attention.
Causes
Acute laryngitis is most often caused by:
- Viral infections (e.g., cold, flu, or upper respiratory tract infections)
- Voice overuse (e.g., yelling, singing, or speaking for long periods)
- Irritants such as smoke, alcohol, or environmental allergens
- Acid reflux (laryngopharyngeal reflux) causing irritation
- Bacterial infections (less common)
In many cases, laryngitis is a secondary symptom of an underlying illness, such as a cold or flu.
Treatment
Most cases of acute laryngitis can be managed at home with self-care measures:
- Voice rest — avoid speaking, whispering, or singing
- Hydration — drink plenty of fluids (water, warm tea with honey)
- Steam inhalation or using a humidifier to soothe the throat
- Throat lozenges or saltwater gargles to relieve irritation
- Avoid irritants such as smoke, alcohol, and spicy foods
- Over-the-counter pain relievers for discomfort (if needed)
If symptoms are severe or caused by a bacterial infection, a doctor may prescribe antibiotics or other medications. Always consult a healthcare professional for persistent symptoms.
