What Causes a Dry, Painful Throat?

There are many potential causes of dryness and pain in the throat, with chronic pharyngitis being the most common. This type of chronic pharyngitis is often triggered by physical irritants—such as airborne dust, tobacco smoke, alcohol, or spicy foods.

The first step is to avoid these irritants—for example, wearing a mask when air quality is poor and reducing intake of spicy or otherwise irritating foods.

A second cause involves underlying inflammation localized to the pharynx itself; in such cases, pharmacological treatment—including anti-inflammatory medications or traditional Chinese patent medicines—may be appropriate.

A third cause is gastroesophageal reflux disease (GERD). In addition to treating pharyngeal symptoms directly, medications targeting gastric and gastrointestinal function may be used to suppress gastric acid reflux and thereby prevent its irritating effect on the pharynx.

Finally, in elderly patients presenting with dryness and pain in the throat, impaired peripheral circulation and age-related degenerative changes may contribute. Alongside standard treatments, supplementation with vitamins or nutritional agents may be considered for older adults to support local secretion—particularly from salivary and mucosal glands—and thus alleviate dryness and discomfort in the throat.
