nátriumvisszatartással
Nátriumvisszatartás refers to the medical condition where the body retains excessive amounts of sodium, leading to an increase in total body sodium content. This retention typically results in a corresponding increase in body water, as sodium and water balance are closely linked. The kidneys play a crucial role in regulating sodium excretion, and impaired kidney function is a common cause of nátriumvisszatartás. Hormonal factors, such as the overproduction of aldosterone, can also contribute by signaling the kidneys to reabsorb more sodium. Certain medications, particularly nonsteroidal anti-inflammatory drugs (NSAIDs) and some blood pressure medications, can interfere with sodium excretion. Conditions like heart failure, cirrhosis of the liver, and nephrotic syndrome are often associated with nátriumvisszatartás due to altered fluid dynamics and hormonal responses. The clinical manifestations of nátriumvisszatartás primarily relate to fluid overload, including edema (swelling), particularly in the legs and feet, weight gain, and shortness of breath due to fluid accumulation in the lungs. Management strategies focus on addressing the underlying cause, which may involve dietary sodium restriction, diuretic medications to promote sodium and water excretion, and treatment of the primary medical condition.
