The fluid accumulated in edema is formed by an aqueous solution of salts and proteins from the blood plasma. An edema can have various causes, such as changes in the wall of a capillary, decreased plasma oncotic pressure, increased hydrostatic blood pressure, sodium retention, and decreased lymphatic drainage.
