J30-J39: Other diseases of upper respiratory tract
J37: Chronic laryngitis and laryngotracheitis
Chronic laryngitis and laryngotracheitis are long-term inflammatory conditions affecting the larynx (voice box) and the trachea (windpipe). These conditions commonly result from ongoing irritation, such as from smoke inhalation, excessive voice use, or persistent exposure to harmful substances. While not contagious, they cause uncomfortable symptoms that impact the respiratory system significantly. Common symptoms include persistent hoarseness, difficulty speaking, a constant cough, and a sensation of a lump in the throat. As these conditions progress, individuals may face complications like vocal cord damage and a lowered quality of life due to persistent discomfort and voice loss. It's essential to note that chronic laryngitis and laryngotracheitis may also result from recurrent acute episodes of these conditions. With these chronic respiratory conditions, symptoms persist for more extended periods, often three weeks or more, distinguishing them from their acute counterparts.
