Dry Mouth and Diabetes: What's the Connection?

Yes, dry mouth can be a sign of diabetes.

Saliva is produced by glands in the mouth and throat. When blood sugar levels are high, the body pulls water from the tissues to dilute the blood, which can lead to dehydration and dry mouth.

Dry mouth can also be a side effect of some diabetes medications.

If you have dry mouth and you are concerned that it may be a sign of diabetes, you should see your doctor.
