4Why Does Hypertonic Dehydration Occur?
In general, hypertonic dehydration occurs as a result of an excess loss of body fluids, typically through the urinary system, gastrointestinal tract, or the skin. As a result, the concentration of sodium in the blood increases, which causes an imbalance of water and sodium. Water loss may be caused by many factors, especially changes in your urine concentration or significant changes in thirst. In healthy adults, urine concentration and thirst are regulated by receptors in your brain, which are responsible for the need for sodium or fluid correction. This typically leads to changes in sodium levels in urine or increased intake of water. These effects may quickly cause hypertonic dehydration. [4]
