Is dry mouth a symptom of diabetes?

Dry mouth is one of the symptoms of diabetes.

When the blood sugar level is too high, it will lead to an increase in sugar in the urine, causing osmotic diuresis, and a large loss of body water, resulting in dry mouth and excessive drinking. Secondly, long-term hyperglycemia may affect the normal function of salivary glands, causing salivary secretion to decrease, resulting in dry mouth. However, in addition to diabetes, there are many other conditions that may cause dry mouth, such as environmental factors, age factors, systemic diseases, etc.

Therefore, when dry mouth symptoms occur, it cannot be simply considered diabetes. Other symptoms, medical history, medication, etc. need to be comprehensively considered, and related tests, such as blood glucose testing, autoantibody testing, etc., should be carried out to determine the cause. If diabetes is suspected, seek medical advice in time for a comprehensive blood glucose test and evaluation.
