Flüssigkeitshaltung

Flüssigkeitshaltung refers to the body's ability to regulate and maintain the correct balance of fluids, both intracellular and extracellular. This process is crucial for numerous physiological functions, including nutrient transport, waste removal, temperature regulation, and maintaining cell structure. The primary organs involved in Flüssigkeitshaltung are the kidneys, which filter blood and adjust urine output to conserve or excrete water and electrolytes. The hormonal system also plays a vital role, with hormones like antidiuretic hormone (ADH) and aldosterone influencing water reabsorption in the kidneys and electrolyte balance.

The balance of electrolytes, such as sodium, potassium, and chloride, is intrinsically linked to fluid balance. These electrolytes help control the movement of water across cell membranes through osmosis. Disruptions in Flüssigkeitshaltung can arise from various factors, including inadequate fluid intake, excessive fluid loss through sweating or vomiting, certain medical conditions like kidney disease or heart failure, and some medications. Symptoms of impaired Flüssigkeitshaltung can range from mild dehydration, characterized by thirst and dry mouth, to more severe conditions like edema (fluid retention) or electrolyte imbalances that can affect nerve and muscle function. Maintaining proper Flüssigkeitshaltung is essential for overall health and well-being.
