👉 Oedema, also known as edema, is a condition in which fluid collects in tissues and organs due to swelling. It can occur in various parts of the body, including the skin, muscles, tendons, and organs. Oedema is often caused by an injury or infection, but it can also be caused by medications, toxins, or other factors that disrupt normal fluid balance. In some cases, oedema can lead to organ failure or death if not treated promptly.
