In medicine, edema is "abnormal fluid accumulation in tissues or body cavities. Most cases of edema are present under the skin in subcutaneous tissue."[1]
Similar terms are:
- Angioedema is "swelling involving the deep dermis, subcutaneous, or submucosal tissues, representing localized edema. Angioedema often occurs in the face, lips, tongue, and larynx."[2]
- Lymphedema is "edema due to obstruction of lymph vessels or disorders of the lymph nodes.[3]
- Myxedema is a "condition characterized by a dry, waxy type of swelling (edema) with abnormal deposits of mucopolysaccharides in the skin and other tissues. It is caused by a deficiency of thyroid hormones. The skin becomes puffy around the eyes and on the cheeks. The face is dull and expressionless with thickened nose and lips."[4]
Extreme cases of edema are called anasarca.
Etiology/cause
- Hydrostatic due to heart failure or venous insufficiency.
- Cirrhosis
- Protein-energy malnutrition including Kwashiorkor and marasmus
- Acute kidney injury or chronic kidney disease
- Obesity
- Medications
Diagnosis
Physical examination
On physical examination, fast recovery of pitting is associated with lower serum albumin levels.[5] Fast recovery within 2-3 seconds, is more sensitive than specific at detecting hypoalbuminemia. Presumably this is related to the viscosity of the interstitial fluid thus hypoalbuminemic interstitial fluid can reform more quickly.[5]
