The causes of hoarseness can be many.
Most often it is a transient phenomenon, related to an inflammation of the vocal cords during an ENT infection (laryngitis). This inflammation impedes the normal vibration of the mucous membranes of the vocal cords, which is why the voice becomes broken and hoarse.
There are also other factors that can cause or worsen hoarseness.
Sometimes, it can be the result of a vocal abuse (having spoken too much, forced on his voice, scraped his throat) often associated with environmental factors (heating, air conditioning, noise, allergies ...).
The irritation of the mucous membranes of the vocal cords may also be related to an excess of tobacco or alcohol, or a lack of sleep.
A lack of hydration may be responsible for overproduction of mucus on the vocal cords and resonance cavities, causing a hoarse voice.
Another cause: a gastro esophageal reflux (passage in the esophagus of a part of the stomach acids), can also be at the origin of a hoarseness.
Children are often affected by episodes of hoarseness due to repeated infections or the fact that they spend a lot of time in noisy environments (schoolyards, gyms, etc.).
Tobacco is also an important factor of aggression of the laryngeal mucous membranes.
When hoarseness persists for more than 8 days, it is important to consult. An examination of the larynx may be necessary. And the opinion of an ENT can be indicated. This is all the more important as this hoarseness is manifested in a person over 35-40 years old, that it has smoked ... the problem can be tumoral.
