What term describes the swelling caused by an increase of fluids within the tissue?

The term that describes the swelling caused by an increase of fluids within the tissue is "oedema." This condition occurs when excess fluid accumulates in the interstitial spaces of the tissues. Oedema can result from various factors, such as inflammation, injury, or systemic conditions like heart failure or kidney disease.

Understanding oedema is crucial in the field of esthetics because it can manifest as puffiness or swelling, particularly in areas like the face. This can affect the appearance of the skin and influence the techniques used for treatments like facials or product recommendations.

In contrast, inflammation refers to the body's response to injury or infection, which may include redness, heat, swelling, and pain, but it encompasses more than just fluid accumulation. Necrosis involves the death of tissue, which is a different biological process. Exudate refers specifically to the fluid that leaks out of blood vessels during inflammation, which is often a part of the complex issues surrounding oedema but does not define the condition itself. Therefore, "oedema" is the precise term for the swelling specifically due to fluid accumulation in the tissues.
