Severe dry mouth may be caused by various factors. Medical conditions are among the main causes, such as diabetes, Sjögren's syndrome, and hyperthyroidism. These diseases may affect the body's endocrine system, leading to reduced saliva secretion and resulting in dry mouth. Unhealthy lifestyle habits, such as breathing with the mouth open for prolonged periods, smoking, and alcohol consumption, can also contribute to dry mouth. Drug side effects are another common cause; certain antihypertensive medications, antihistamines, and others may interfere with normal saliva secretion. Age-related factors may also play a role, as salivary gland function may decline with age, making elderly individuals more prone to experiencing dry mouth. Therefore, for severe cases of dry mouth, it is recommended to seek timely medical consultation to identify the specific cause and implement appropriate treatment measures.
