Oedema: Swelling caused by the accumulation
of fluid in the extra-vascular tissue. Oedema
usually affects the feet, ankles and legs,
although it can occur anywhere in the body.
The cause of oedema should be identified
before beginning treatment. Bilateral oedema
is indicative of systemic conditions such as
cardiac failure, protein reduction and venous
insufficiency, standing or sitting in the same
position for too long, eating a large amount of
salty foods, being overweight, being pregnant,
malignancy or taking certain medicines.
Unilateral oedema is more often due to local
causes, such as deep vein thrombosis or
cellulitis.

Chronic lower limb oedema is a persistent,
abnormal swelling of the leg. Chronic oedema
has an ongoing effect on the viability of the skin
leading to complications, such as infection,
