ADH, Antidiuretic Hormone, Vasopressin

ADH inhibits diuresis by enhancing renal water reabsorption in the kidney collecting tube. ADH or vasopressin plays an important role in the regulation of osmotic pressure and fluid volume in the body. It concentrates urine by increasing the recovery of water from primary urine. It is excreted mainly at night and helps to sleep through the night without the need to urinate.

ADH wird im Hypothalamus gebildet, in den Hypophysenhinterlappen transportiert und dort durch verschiedenste Regulationsmechanismen in die Blutbahn abgegeben.
ADH besitzt antidiuretische Wirkung, indem es die Wasserrückresorption in den distalen Tubuli sowie in den Sammelrohren der Niere fördert. Dadurch geht dem Körper möglichst wenig Wasser verloren. Die vasopressorische Wirkung des ADH führt zur arteriellen Vasokonstriktion und damit zu einer Blutdruckerhöhung. Die ADH-Ausschüttung wird im Rahmen des osmoregulatorischen Systems gesteuert.

ADH, Antidiuretic Hormone, Vasopressin

ADH inhibits diuresis by increasing renal water reabsorption in the collection tube of the kidney. ADH or vasopressin plays an important role in regulating osmotic pressure and fluid volume in the body. It concentrates urine by increasing the recovery of water from primary urine. It is excreted mainly at night and helps to sleep through the night without the need to urinate.

ADH is formed in the hypothalamus, transported into the posterior pituitary gland and released into the bloodstream through various regulatory mechanisms. ADH has an antidiuretic effect by promoting water reabsorption in the distal tubules as well as in the collection tubes of the kidney. This means that as little water as possible is lost to the body. The vasopressor effect of ADH leads to arterial vasoconstriction and thus to an increase in blood pressure. ADH distribution is controlled by the osmoregulatory system.
