Laryngitis is defined as inflammation or irritation of the larynx, which is the voice box that lies at the base of the throat just above the windpipe. It's a situation or symptom rather than a distinctive disease. Acute laryngitis is defined as lasting 3 weeks or much less; laryngitis that lasts longer than 3 weeks is known as chronic laryngitis.
Laryngitis happens when the vocal folds (or vocal cords) swell as a result of infection or an additional cause of inflammation. The vocal folds are two bands of tissue that stretch across the larynx. Under normal circumstances, when an individual desires to speak, the vocal folds tighten. Air from the lungs is forced through the smaller space between the bands of muscle, causing them to vibrate.
Lengthening, shortening, tightening, and loosening of the cords allows an individual to control the pitch of the voice. When the vocal folds swell up because of irritation or inflammation, they cannot vibrate effortlessly, which causes the voice to sound hoarse, raspy, or faint.
Probably the most typical single trigger of acute laryngitis is an upper respiratory infection caused by a virus, most frequently a cold or influenza virus. Other viruses, such as those that trigger chickenpox, mumps, or measles, may also cause laryngitis. Other causes of laryngitis include:
