Lymphoedema

Part of speech: noun

Definitions

1. A medical condition defined by the buildup of lymph fluid in body tissues, causing swelling primarily in limbs, resulting from impaired lymphatic drainage capabilities
2. This disorder features the accumulation of lymphatic fluid in the body's tissues, which leads to noticeable swelling, particularly in the arms and legs, often due to lymphatic system failure
3. A pathological state characterized by the excessive accumulation of lymph fluid in the interstitial tissues, leading to significant swelling in the extremities and often resulting from lymphatic system dysfunction

Etymology: Lymphoedema is built from "lympha", Latin for water or clear fluid, and the Greek-derived "oidema", meaning swelling. Put together, the word describes the swelling that results when lymph, the watery fluid that drains from body tissues, fails to flow away properly. The "lympha" element is the same Latin root that gives English "lymph", so the name sums up the condition in its two parts: fluid and swelling. The spelling "lymphoedema" keeps the British "oe" form of the Greek-derived ending, while American English usually writes "lymphedema" with a plain "e". Both refer to the same condition, and the difference is simply a matter of regional convention.
