Edema (American English), also spelled oedema (Commonwealth English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue.[1][4] Most commonly, the legs or arms are affected.[1] Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness.[1] Other symptoms depend on the underlying cause.[2]
Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema.[1][2] It may also occur in immobile patients (stroke, spinal cord injury, aging), or with temporary immobility such as prolonged sitting or standing, and during menstruation or pregnancy.[1] The condition is more concerning if it starts suddenly, or pain or shortness of breath is present.[2]
Treatment depends on the underlying cause.[2] If the underlying mechanism involves sodium retention, decreased salt intake and a diuretic may be used.[2] Elevating the legs and support stockings may be useful for edema of the legs.[3] Older people are more commonly affected.[3] The word is from the Ancient Greek οἴδημα oídēma meaning 'swelling'.[5]
