What causes a person to constantly clear their throat?

Acid reflux and sinus drainage can cause a person to continuously clear their throat. Allergies and medication side effects can also cause this.

The reason for constant throat clearing should be evaluated by a medical professional. Other symptoms that occur with the throat clearing include a dry cough or a tickle in the throat. An exam is required as part of the diagnosis process. On occasion, an endoscopy is warranted. The procedures consists of a thin camera or video device being inserted through the nose or down the throat to check for problematic areas. The treatment depends on the exact cause of the throat clearing, according to the Fauquierent Ear Nose & Throat Consultants of Virginia.
