edema (edē´m),

n the accumulation of fluid in the tissues or in the peritoneal or pleural cavities. Primary factors favoring edema are increased capillary hydrostatic pressure (increased venous pressure), decreased osmotic pressure of plasma (hypoproteinemia), decreased tissue tension and lymphatic drainage, increased osmotic pressure of tissue fluids, and increased capillary permeability. Additional renal and hormonal factors are important. Clinical manifestations may consist of a steady weight gain or localized or generalized swelling.
