What is laryngitis?
Key points
Different conditions can cause inflammation that result in laryngitis, like viral infections and environmental factors.
Common symptoms include a weakened voice and a dry cough.
If a virus caused your acute (short-term) laryngitis, the symptoms usually disappear without treatment within seven days.
Laryngitis occurs when your voice box or vocal cords become inflamed from overuse, irritation, or infection. Laryngitis can be acute (short-term), lasting less than three weeks. Or it can be chronic (long-term), lasting more than three weeks.
Many conditions can cause the inflammation that result in laryngitis. Viral infections, environmental factors, and, bacterial infections can all cause laryngitis.

CAUSES
What causes laryngitis?
Acute laryngitis is a temporary condition caused by overusing the vocal cords. Or it can be caused by an infection. Treating the underlying condition causes the laryngitis to go away.
Chronic laryngitis results from long-term exposure to irritants. And it is usually more severe and has longer-lasting effects than acute laryngitis.
Acute laryngitis can be caused by:
viral infections
straining your vocal cords by talking or yelling
bacterial infections
Chronic laryngitis can be caused by:
frequent exposure to harmful chemicals or allergens
acid reflux
frequent sinus infections
smoking or being around smokers
overusing your voice
low-grade
yeast infections caused by frequent use of an asthma inhaler
Cancer, paralysis of the vocal cords, or changes in vocal cord shape as you age can also cause persistent hoarseness and sore throats.
SYMPTOMS
Symptoms of laryngitis
The most common symptoms of laryngitis include:
weakened voice
loss of voice
hoarse, dry throat
constant tickling or minor throat irritation
dry cough
These symptoms are usually mild and can be treated by giving your voice a break. Drinking water or other noncaffeinated fluids can help lubricate your throat.

INFANTS AND CHILDREN
Laryngitis in infants and children
Infants and children can be prone to laryngitis if they’re frequently around other children. Both viral and bacterial infections can spread quickly from child to child. Laryngitis can also develop if your child yells or sings a lot. This causes bumps to form on their vocal cords.
If you notice your child’s voice is hoarse or weak or they say that their throat hurts, make sure they rest their voice. Also have them drink fluids to ease possible
viral laryngitis. Laryngitis usually goes away within a week.
If your child’s symptoms don’t improve or become worse, see their doctor. A doctor can determine if other factors are causing laryngitis or if antibiotics for a bacterial infection are needed.
Certain symptoms could also indicate your child has a serious bacterial infection around the voice box, called the epiglottis. The epiglottis is the flap of tissue that covers the larynx (voice box) and trachea (breathing tube) when you eat or drink. It keeps food particles and liquid out of your lungs.
Epiglottitis is an infection of the epiglottis and the tissue around it. During epiglottitis, tissue swells to the point that it can close off the windpipe.
Epiglottitis can be fatal if not treated. See a doctor right away if your child has:
trouble swallowing
problems breathing (or needs to lean forward in order to breathe)
extra saliva
noisy, high-pitched sounds when breathing
a muffled voice
a fever
Typically, your child will require a hospital stay to receive treatment. Your child will be given IV antibiotics and often glucocorticoids or
dexamethasone.
Epiglottitis mostly affects children ages 2 to 6 years old. But a child of any age, or adult, can be affected. The Hib vaccine protects children from the bacteria
Haemophilus influenzae type b. The vaccine has helped reduce the number of cases of epiglottitis caused by these bacteria.

WHEN TO SEE A DOCTOR
When to see a doctor
You could also have common symptoms that mean you have a condition similar to laryngitis, including:
lesions such as ulcers, cysts, or nodules on your vocal cords
muscle tension dysphonia, a vocal condition caused by abnormal use of the vocal muscles
vocal cord paralysis
Some symptoms can be serious or indicate underlying issues. These symptoms include:
trouble swallowing
coughing up blood
a fever that doesn’t go away with treatment
debilitating pain in your throat
See your doctor if common symptoms don't clear up after a week, or they worsen.

DIAGNOSIS
Diagnosing laryngitis
Laryngitis affects your vocal cords and voice box. Your doctor often starts with a visual diagnosis, using a special mirror to view your vocal cords. They might also perform a
laryngoscopy to magnify the voice box for easy viewing. During a laryngoscopy, your doctor sticks a thin, flexible tube with a microscopic camera through your mouth or nose. Your doctor then looks for the following signs of laryngitis:
irritation
redness
lesions on the voice box
widespread swelling, a sign of environmental causes of laryngitis
vocal cord swelling, which can be a sign that you’ve overused your vocal cords
If your doctor sees a lesion or other suspicious mass, they may order a biopsy to rule out
throat cancer. During a biopsy, your doctor removes a small piece of tissue so it can be examined in a lab.
TREATMENT
How is laryngitis treated?
If a virus has caused acute laryngitis, symptoms usually disappear without treatment within seven days. Doctors treat
bacterial laryngitis with antibiotics, although this form of laryngitis is rare.
Treatments to ease symptoms
Your doctor might prescribe
corticosteroids, medicines that can reduce inflammation, to treat both acute and chronic laryngitis.
These treatments help reduce vocal cord and voice box swelling. Corticosteroids can treat and relieve symptoms of laryngitis, especially acute viral laryngitis. For chronic laryngitis, the best treatment will address the cause of the underlying problem.
Laryngitis Tips
Use a humidifier or inhale steam to alleviate dryness.
Get vocal therapy to analyze and correct the way you use your voice and any abnormal speech patterns that place stress on your vocal cords and voice box.
Drink lots of fluids.
Gargle with 1/2 tsp. of salt and 1/2 tsp. of baking soda in 8 oz. of warm water.
Rest your voice.
Avoid screaming or talking loudly for long periods of time.
Avoid decongestants, which can dry your throat.
Suck on lozenges to keep your throat lubricated.
Refrain from whispering, which can strain the voice. if problem persists consult your doctor
