Plasma osmolality

Plasma osmolality refers to the concentration of dissolved substances, such as salts and sugars, in the blood. It helps determine how well water is balanced in the body. When osmolality is normal, it means there’s a healthy level of fluids and solutes, crucial for proper cell function. If the levels are too high or too low, it can lead to dehydration or overhydration, affecting vital processes. Medical professionals often check plasma osmolality to diagnose conditions like diabetes or kidney problems, ensuring the body maintains its necessary balance of fluids and electrolytes.
