Long-term exposure to irritants, cigarette smoking and acid reflux are among the factors that can cause chronic laryngitis, according to Mayo Clinic. Excessive hoarseness or voice loss can also occur in singers who overuse their vocal cords or individuals with chronic sinus problems.
Nodules or polyps that develop on the vocal cords, nerve damage or cancer can also cause chronic vocal loss, states WebMD. In certain cases, the vocal cords may naturally weaken with the aging process and lead to continual hoarseness. It is important for individuals with symptoms of laryngitis that last longer than two weeks to consult with a physician to ensure proper diagnosis and treatment. Hoarseness and laryngitis can also indicate yeast infections caused by long-term use of asthma inhalers, explains Healthline. Additional symptoms of laryngitis can include throat dryness, dry cough and a constant tickle in the throat.
Depending on the underlying cause, treatments for laryngitis can include increased intake of fluids, vocal therapy, salt water gargling, humidifier treatments and throat lozenges that promote lubrication of the throat, notes Healthline. Individuals with acute or chronic laryngitis may also benefit from corticosteroid treatments that help to minimize vocal cord swelling. Avoiding excessive amounts of alcohol, caffeine and cigarette smoke can help to keep the vocal cords healthy and prevent recurrence.
