Laryngitis

Laryngitis occurs when your larynx, or voice box, is inflamed. The condition can develop when your vocal cords are overused, irritated or infected.

When your vocal cords function normally, they open and close smoothly, producing sounds through vibration. However, when your vocal cords are swollen, the sounds that pass through them are distorted. As a result, your voice sounds weak or hoarse.

What’s the difference between laryngitis and pharyngitis?

Though the terms laryngitis and pharyngitis sound similar, these conditions are different. Pharyngitis refers to an inflamed pharynx. It’s the medical term for a sore throat. Your pharynx starts behind your nose and ends just above your voice box. Laryngitis refers to an inflamed larynx, or voice box. Your larynx is near your pharynx, just above your windpipe.

Who can get laryngitis?

Laryngitis can affect people of all ages. You’re more prone to this condition if you:

• Overuse your voice.
• Are frequently exposed to tobacco smoke.
• Are a heavy drinker.
• Have a respiratory infection, such as bronchitis or sinusitis.
• People who are immunocompromised or who are on inhaled steroids can be at risk for fungal laryngitis.

How common is laryngitis?

There are two types of laryngitis: acute and chronic. Acute laryngitis is temporary, common and usually improves once the underlying cause is treated. While some people are more prone to laryngitis, most adults develop the condition once every couple of years.

If laryngitis is present longer than three weeks, it’s considered chronic. Research suggests that about 21% of Americans will develop chronic laryngitis at some point in their lives.

How does laryngitis affect my body?

When you get laryngitis, your vocal cords become, swollen and irritated. As a result, your voice can be affected, and sometimes is reduced to a whisper.
