Customer question:
What could be causing constant throat irritation? Anonymous customer's question
Pharmacist's answer:
Various factors can cause constant throat irritation. One of the more common is allergy, where substances such as dust, pollen, animal dander, or mold irritate the lining of the throat. Another common cause is postnasal drip, where mucus from the nose runs down the back of the throat, typical of chronic sinusitis or allergic rhinitis. Gastroesophageal reflux disease can also irritate, as stomach acid backs up into the esophagus and throat, causing an unpleasant burning sensation and irritation.
Dry throat can result from exposure to dry air, especially in the winter months or in rooms with low humidity. Smoking and exposure to cigarette smoke or other irritants such as chemicals or air pollution can also cause persistent irritation. Viral or bacterial infections are another possible cause, causing inflammation and irritation that may persist even after the primary infection has subsided. Chronic inflammation of the tonsils or inflammation of the throat can cause constant discomfort.
Some medications can have side effects that cause dryness and irritation in the throat. Examples include antihistamines, diuretics, and some high-blood pressure medications. Also, frequent use of the voice, such as by singers, teachers, or those who talk a lot, can irritate due to the overloading of the vocal cords. Psychological factors such as stress and anxiety can cause dryness or tightness in the throat, also known as Globus hystericus. Autoimmune diseases such as Sjögren's syndrome, where the body attacks its glands that produce saliva and tears, can cause chronic dryness in the mouth and throat.
