Cardiogenic edema occurs when the right heart failure due to heart disease, venous blood cannot be drained into the left ventricle, caused by intravenous pressure increases and the fluid leakage into the interstitial space, causing edema, first appeared in the ankle, the last throughout the body.
Renal edema due to acute and chronic nephritis or nephropathy, renal blood flow reduction of sodium and water retention, increased capillary permeability, reduce urinary protein loss of plasma colloid osmotic pressure caused by too much, can make tissue interstitial fluid accumulation caused by edema. Edema, although common in the lower extremities, occurs first in the eyelids and face, and then affects the lower extremities and the whole body. It is accompanied by oliguria or nocturia and polyuria.
Hepatic edema is mainly due to the destruction of the structure of liver cirrhosis, portal venous obstruction caused by the increase and static pressure, but with malnutrition, liver failure, low plasma albumin is also related to edema from the ankles began to spread, but with significant ascites is most obvious, and the upper limbs and head and face a little wave.
Malnutrition, edema, malnutrition, plasma albumin and edema, the first appeared in the lower limb, gradually spread upward and throughout the body. Before edema, malnutrition, malabsorption, or chronic wasting disease are present.
Local edema of lower limbs due to venous and lymphatic vessels blocked fluid into the interstitial space caused by the following limb thrombophlebitis, lymphatic filariasis, pelvic inflammation, tumor compression or lower extremity vein, edema often occurs in unilateral lower extremity, generally do not spread the body.
