What causes a dry throat and a dry, parched mouth?

The causes of a dry throat, dry mouth, and parched tongue may involve multiple factors. Environmental factors are an important cause; for example, dry weather and low air humidity during autumn and winter, or prolonged time spent in dry environments such as air-conditioned rooms, can all potentially lead to a dry throat. Lifestyle habits may also contribute to this symptom. For instance, insufficient water intake, or prolonged speaking or singing, can cause excessive evaporation of moisture from the mouth and throat, resulting in dryness. Disease-related factors should not be overlooked either, such as chronic pharyngitis, diabetes, and Sjögren's syndrome, which can all cause a dry throat, dry mouth, and parched tongue. Particularly for diabetic patients, elevated blood sugar levels can lead to increased fluid loss in the body and cause thirst. As the causes of a dry throat, dry mouth, and parched tongue are varied, diagnosis and treatment must be based on individual circumstances. Patients with concerns are advised to seek timely medical consultation.
