What are the common causes of dry mouth and a parched throat?

Common causes of dry mouth and thirst typically include the following: 1. Physiological factors: Prolonged lack of water intake, rapid breathing, strenuous exercise, and similar conditions may result in insufficient saliva production, leading to dryness in the mouth. 2. Environmental factors: Dry climates and air-conditioned rooms can cause evaporation of moisture from the oral cavity, resulting in dry mouth and thirst. 3. Disease-related factors: Conditions such as diabetes, Sjögren's syndrome, and oral candidiasis may impair the function of salivary glands, causing dry mouth. 4. Medication-related factors: Certain medications, such as antihypertensives and anticholinergics, can reduce saliva secretion in the mouth, leading to dryness. 5. Psychological factors: Emotional tension, anxiety, excessive stress, and other psychological factors may also contribute to dry mouth and thirst. Patients with concerns are advised to seek timely medical consultation.
