Plasma volume expansion

Plasma volume expansion refers to an increase in the amount of plasma—the liquid part of blood—that circulates through the body. This can happen when the body retains more water or produces more plasma, often in response to conditions like dehydration, blood loss, or certain medical treatments. An expanded plasma volume helps maintain blood pressure and ensures that vital organs receive enough oxygen and nutrients. Essentially, it's the body's way of increasing the liquid component of blood to support proper circulation and overall health during various physiological or pathological states.
