Excessive accumulation of fluid in the tissues and cavities of the body. More often this phenomenon is observed in the skin, subcutaneous fatty tissue, pleural, abdominal cavity, pericardial shirt, scrotum, etc.
The edematous fluid contains water, sodium and potassium salts, a certain amount of protein and leukocytes. There are more of the latter in the inflammatory nature of O. Through the vascular capillaries there is a constant exchange between tissue fluid and the liquid part of the blood.
The release of fluid through the walls of blood vessels into the surrounding tissue occurs continuously. If a large amount of fluid is released into the surrounding tissue from the vessels, and reabsorption is difficult or has completely stopped, O is formed. This process is also facilitated by changes in the content of sodium and potassium, as well as proteins in the vascular bed and in the surrounding tissues.
The causes of edema may be associated with diseases of the heart, liver, and kidneys. For treatment, diuretics and drugs that regulate water-salt metabolism are used. It is important to see a doctor in a timely manner to prevent complications.
