Most of the fluid deficit during the early stages of dehydration is from the extracellular space , but over time, the fluid losses equilibrate, and fluid leaves the intracellular space.
What happens to extracellular fluid during dehydration?
In dehydration, fluid from the extracellular compartment is depleted first, followed by fluid from the intracellular space . Fluid loss from the intracellular space results in cellular shrinkage and metabolic dysfunction.
How do you classify dehydration?
Dehydration can be classified as hypotonic, isotonic, or hypertonic , depending on the change in concentration of electrolytes in relation to water (Huether, 2019).
Is dehydration hypotonic or hypertonic?
Sodium and water losses are of the same relative magnitude in both the intravascular and extravascular fluid compartments. Hyponatremic (hypotonic) dehydration occurs when the lost fluid contains more sodium than the blood (loss of hypertonic fluid). Relatively more sodium than water is lost.
What happens to cells when dehydrated?
If dehydration continues, tissues of the body begin to dry out, and cells begin to shrivel and malfunction . In severe dehydration, the sensation of thirst may actually decrease and blood pressure can fall, causing light-headedness or fainting, particularly upon standing (a condition called orthostatic hypotension.

What are the three types of dehydration?
[3] There are three main types of dehydration: hypotonic (primarily a loss of electrolytes), hypertonic (primarily loss of water), and isotonic (equal loss of water and electrolytes) . The most commonly seen in humans is isotonic. [4] Etiology Body water is lost through the skin, lungs, kidneys, and GI tract.
Is being dehydrated hypertonic?
Hypertonic dehydration occurs when there’s an imbalance of water and salt in your body . Losing too much water while keeping too much salt in the fluid outside your cells causes hypertonic dehydration.
How does isotonic solution treat dehydration?
Hypotonic • A hypotonic solution shifts fluid out of the intravascular compartment, hydrating the cells and the interstitial compartments. Isotonic • Because an isotonic solution stays in the intravascular space, it expands the intravascular compartment .
