👉 Blocked fluid, also known as colloid-free fluid or non-colloid fluid, refers to a type of bodily fluid that lacks the normal colloidal particles that typically suspend smaller particles in solutions like blood plasma. In a healthy circulatory system, proteins and other macromolecules form colloids that help maintain the fluid's viscosity and prevent it from clotting. When these particles are blocked, often due to inflammation, infection, or injury, the fluid cannot circulate freely, leading to impaired organ function and potentially serious complications such as edema or impaired immune response. This condition is often seen in conditions like sepsis, where the body's immune response causes widespread inflammation and fluid leakage into tissues.
