Dry mouth occurs because adequate saliva production is hindered; without enough fluids, the mouth can become parched and uncomfortable. Dizziness is a typical symptom due to decreased blood volume or pressure, which can result when the body is low on fluids and unable to maintain proper circulation. Confusion can indicate more severe dehydration as it affects cognitive function; the brain needs sufficient fluids to operate efficiently, and even mild dehydration can lead to impaired mental clarity.
