Dry Mouth and Excessive Thirst

Welcome to the symptom guide regarding dry mouth and/or excessive thirst. We're sorry to hear you're having this problem! This symptom guide is designed for persons who have noticed dryness of the mouth and/or unexplained thirst and would like to find out more about this condition. Please keep in mind that this guide cannot replace a face-to-face evaluation with your own doctor. It is meant to provide helpful information while you are awaiting further evaluation or to supplement what you may have already learned after evaluation with your doctor. This guide will focus on dry mouth that has been persistent over time. Temporary dryness of the mouth may accompany nervousness, anxiety, and breathing through the mouth (as many people do when they sleep). Eating a salty or spicy meal can be a cause of temporary (though intense) thirst.
