Laryngitis symptoms are common and often linked to viral infections, voice strain or reflux. While many cases settle on their own, persistent hoarseness can signal an underlying problem that requires specialist assessment.
Understanding the difference between short term inflammation and ongoing voice change is key. Hoarseness lasting more than three weeks should always be assessed by an ENT specialist.
What is laryngitis?
Laryngitis is inflammation of the larynx, often called the voice box. The larynx sits at the top of the windpipe and contains the vocal cords, which vibrate to produce sound.
When the vocal cords become inflamed, their vibration changes. This leads to hoarseness, voice loss or a change in pitch.
There are two main types:
Acute laryngitis which develops suddenly and usually lasts up to one to two weeks.
Chronic laryngitis where symptoms persist for more than three weeks.
This distinction is important. Acute laryngitis is often viral and self limiting. Chronic laryngitis symptoms may indicate ongoing irritation such as acid reflux, smoking related inflammation or vocal strain.
What are the main symptoms of laryngitis?
The classic symptoms of laryngitis affect the voice and throat.
Hoarseness or voice change
Hoarseness is the most common symptom. The voice may sound rough, weak or strained.
Some people experience laryngitis voice loss, where the voice becomes very faint or disappears completely.
Sore or raw throat
The throat may feel dry, irritated or scratchy rather than severely painful. This helps distinguish laryngitis from tonsillitis, which typically causes significant pain and difficulty swallowing.
Dry cough
A persistent dry cough is common, particularly with viral laryngitis or reflux related irritation.
Frequent throat clearing
Repeated throat clearing can both result from and worsen laryngeal irritation. Some patients also benefit from understanding the behavioural aspect of throat symptoms, explored further in our article on throat clearing psychology.
Difficulty swallowing or a lump sensation
Some people describe a feeling of a lump in the throat, known medically as globus sensation. This is often linked to reflux or muscle tension rather than a structural blockage.
Can laryngitis cause complete voice loss?
Yes. In acute cases, swelling of the vocal cords can prevent normal vibration, resulting in temporary loss of voice.
Complete voice loss can be alarming but is usually short lived in viral laryngitis. However, if voice loss persists beyond three weeks, further assessment is essential.
Laryngitis vs sore throat: what is the difference?
People often ask how do I know if I have laryngitis rather than a standard sore throat.
The key difference lies in the voice.
Laryngitis primarily affects the voice, causing hoarseness or voice loss with mild throat discomfort.
Tonsillitis usually causes significant throat pain, fever and swollen tonsils.
A simple sore throat may cause pain without altering the voice significantly. If hoarseness is the dominant symptom, the larynx is likely involved.

Acute laryngitis: causes and duration
Acute laryngitis is most commonly caused by viral upper respiratory infections. According to NHS guidance, it usually improves within one to two weeks.
Other causes include:
- Short term vocal overuse such as shouting or singing
- Irritation from smoke
- Allergies
How long does laryngitis last?
Most cases settle within 7 to 14 days. During this time, vocal rest is the single most important step in recovery.
Self care for acute laryngitis
- Rest your voice as much as possible
- Avoid whispering, which strains the larynx more than quiet speech
- Drink plenty of fluids
- Avoid smoking and smoky environments
- Limit caffeine and alcohol
Whispering forces the vocal cords into a strained position. Speaking gently at a normal pitch is less harmful than whispering.
If symptoms improve steadily over two weeks, no further treatment is usually required.
Is laryngitis contagious?
Acute viral laryngitis can be contagious because it is often part of a common cold or respiratory infection.
Chronic laryngitis symptoms caused by reflux, smoking or vocal strain are not contagious.
Chronic laryngitis symptoms and causes
Chronic laryngitis refers to inflammation lasting more than three weeks. This is the most important threshold for ENT assessment.
Acid reflux and LPR
One of the most common causes is laryngopharyngeal reflux, often shortened to LPR. This occurs when stomach acid reaches the throat and voice box.
Unlike typical heartburn, LPR may not cause chest discomfort. Chronic laryngitis from acid reflux is often present without heartburn, which makes it easy to miss.
Symptoms include:
- Persistent hoarseness
- Chronic throat clearing
- A lump sensation
- Ongoing dry cough
Further information is available in our guide to gastro-oesophageal reflux throat symptoms.
Vocal overuse
Teachers, singers, call centre workers and public speakers are particularly at risk. Repeated strain can lead to swelling or small lesions on the vocal cords.
Smoking and environmental irritants
Tobacco smoke is a significant irritant to the larynx and increases the risk of more serious conditions affecting the voice.
Postnasal drip
Excess mucus from the nose or sinuses can irritate the throat and contribute to chronic symptoms.
Red flag symptoms: when should I see a doctor for laryngitis?
Hoarseness persisting beyond three weeks always warrants ENT assessment.
Additional warning signs include:
- Difficulty breathing
- Difficulty swallowing
- Pain when swallowing
- Blood in mucus
- Unexplained weight loss
- Persistent ear pain with normal ear examination
While most cases are benign, persistent voice change must be examined to exclude vocal cord lesions or more serious pathology. NICE guidance on suspected cancer referral emphasises that unexplained persistent hoarseness should prompt urgent assessment.
If you experience severe breathing difficulty seek urgent medical attention.
What happens during an ENT assessment?
An ENT consultation focuses on understanding symptom duration, triggers and voice use patterns.
Examination may include:
Flexible nasopharyngoscopy: a thin camera passed gently through the nose to view the larynx.
Stroboscopy: using a flashing light to assess vocal cord vibration in detail.
These procedures are usually performed in clinic and take only a few minutes.
A tailored treatment plan may involve reflux management, voice therapy, medication or lifestyle changes depending on the underlying cause.
Patients with persistent symptoms are assessed in our private voice clinic, where detailed voice analysis and specialist input are available.
Understanding laryngitis symptoms and recovery
Laryngitis symptoms most commonly include hoarseness, voice change and mild throat discomfort.
In many cases, particularly when linked to a viral infection, symptoms settle within one to two weeks. During this time vocal rest is the most important part of recovery. Avoid whispering, as it places more strain on the vocal cords than speaking gently at a normal pitch.
When symptoms persist beyond three weeks they are considered chronic. Persistent hoarseness should always be taken seriously and assessed appropriately.
When to seek specialist advice
Hoarseness lasting more than three weeks should always be assessed by a specialist.
If you are experiencing ongoing voice change, persistent throat irritation or chronic cough, expert evaluation can provide clarity and reassurance.
