What Are the Causes of Pitting Edema?
The causes of pitting edema are usually linked to an underlying condition that affects various organs or limbs of the body, causing fluid retention. The most common underlying diseases include heart disease, kidney disease, and liver disease. In addition, varicose veins and inflamed veins may be causes of pitting edema. Pitting edema may also be caused by pregnancy, poor diet, and certain medications. Edema is the swelling of a person’s body tissue, usually in the legs, feet, hands, or arms. The swelling is caused by an accumulation of body fluids underneath the surface of the skin. Pitting edema can usually be identified when a person applies pressure to the swollen portion of the skin. If pitting edema is present, an indication will persist after the pressure is released. Pitting edema is more common that non-pitting edema, where an indentation does not persist after the release of pressure to the swollen area.
