Related to oedema: pitting oedema, Pulmonary oedema
oedemaExcessive accumulation of fluid, mainly water, in the tissue spaces of the body. Oedema may be local, as at the site of an injury, or general. It often affects specific organs, such as the brain or the lungs. It may be caused by injury, allergy, starvation, HEART FAILURE, kidney failure or disease-especially the NEPHROTIC SYNDROME, liver disease-CIRRHOSIS, hormonal changes in the menstrual cycle, varicose veins or poisoning. General oedema is often treated with DIURETIC drugs.
edemaa swelling of tissues caused by the capilliary blood vessels passing out water into the surrounding tissues, and so increasing the intercellular fluid content.
oedemaaccumulation of excess tissue fluid in distal limb tissues associated with e.g. local inflammation/infection, abnormal lymphatic drainage, abdominal mass or cardiac/lung/renal dysfunction (Table 1)
anaphylactic oedema generalized swelling of facial skin and mucous membranes with associated difficulty in breathing and profound drop in blood pressure; characteristic of anaphylaxis (see anaphylaxis)
cardiac oedema peripheral oedema due to congestive heart failure
joint oedema oedema of joint soft tissues, due to joint (e.g. rheumatoid or osteoarthritis) or ligamentous inflammation (e.g. mechanical trauma, joint strain/sprain)
non-pitting oedema indurated and firm oedematous lower-limb tissues; indicative of long-standing oedema and fibrosis, e.g. in long-term venous incompetence
peripheral oedema oedema of distal (foot and limb) tissues secondary to e.g. cardiac, pulmonary or renal dysfunction, venous dysfunction, abdominal mass or hypertension
pitting oedema relatively soft, tissue oedema affecting both feet and lower legs or unilateral swelling of a limb with incompetent venous return; characterized by retention of the depression caused by fingertip pressure
pulmonary oedema lung oedema due to heart valve dysfunction
|Unilateral||Within the limb|
Local, e.g. as the result of local trauma, inflammation or infection
Regional, e.g. as the result of proximal limb trauma, inflammation, infection or venous compromise
|Bilateral||Systemic disease (e.g. heart disease, renal dysfunction, abdominal mass, hypertension, lung dysfunction)|
|Pitting||Systemic disease (e.g. heart disease; hypertension; venous compromise)|
|Indurated/non-pitting||Long-standing oedema (e.g. marked venous compromise; subsequent to deep-vein thrombosis)|
Patient discussion about oedema
Q. does mosquito bites considered as an edema a bet with a friend- please help solve an issue an help me win a new I pod :)
Q. what is "pulmonary edema" and what are the risks? my Dr. told me I'm in a risk group for pulmonary edema, he tried to explain what it is but i didn't understand fully...if someone may give me a brief explanation- I'll appreciate it!
