Laryngitis is the swelling and inflammation of the larynx's mucous membrane, typically caused by infection, irritation, or overuse. Within the larynx are the vocal cords, two folds of mucous membrane covering muscle and cartilage, which open and close rhythmically to produce sound.

Acute laryngitis often results from viral or bacterial respiratory infections, excessive talking, yelling, loud singing, or heavy alcohol consumption. Chronic laryngitis, however, develops from prolonged exposure to irritants, acid reflux, chronic rhinosinusitis, smoking, continuous and excessive talking, or fungal superinfections from regular asthma inhaler use.

Indeed, prolonged and intense speaking can strain and swell the vocal cords, leading to laryngitis. Furthermore, vocal cords may develop nodules, polyps, or Reinke's edema (vocal cord swelling), resulting in persistent hoarseness that requires specialized treatment.

Laryngitis irritates and swells the vocal cords, distorting sound as air passes through them, which alters or weakens the voice, causing hoarseness or voice loss. Other symptoms include shortness of breath, a weak voice, coughing, a sensation of something stuck in the throat, difficulty swallowing, and frequent throat clearing.

Treatment for laryngitis varies by severity, with specialists prescribing medication and voice therapy. Patients can also adopt supportive measures: drinking plenty of water, avoiding alcohol and caffeine, using a humidifier, gargling daily with saline solution, and using lozenges. These practices help soothe the vocal cords, alleviate symptoms, and shorten recovery time.

For individuals whose jobs require frequent speaking, like yours, it is crucial to rest your voice, avoid speaking loudly, drink ample water, and keep your mucous membranes hydrated. If hoarseness persists for two to three weeks without improvement, consult an ENT specialist for an endoscopic examination, evaluation, diagnosis, and appropriate treatment.
