Symptom 2: Dry Mouth and Throat
Dry mouth and throat, medically known as xerostomia and xeropharynx, respectively, are common symptoms of hypernatremia. These occur as a consequence of the body’s attempt to maintain fluid balance in the face of high sodium concentrations. When blood sodium levels rise, water is drawn out of cells and into the bloodstream through the process of osmosis. This results in a decrease in the body’s overall water content and leads to the drying of mucous membranes, particularly in the oral cavity and throat.
The sensation of dry mouth and throat can be uncomfortable and may cause difficulties in speaking, swallowing, and tasting. Additionally, it can lead to complications such as dental issues, gum disease, and bad breath. In hypernatremia, these symptoms often coexist with intense thirst, as the body seeks to increase fluid intake and restore electrolyte balance.
It is crucial to identify and treat the underlying cause of hypernatremia to alleviate these symptoms. Treatment may involve the administration of fluids to rehydrate the body and gradually correct the sodium imbalance. In some cases, addressing the root cause may require adjustments to medications or treatment of underlying medical conditions. (2)
