Zusammenfassung
Die Regulation des Energiestoffwechsels ist ein komplexes Wechselspiel zwischen Hormonen, exogenen Nährstoffen und dem Austausch von Substraten mit dem Ziel, eine konstante und ausreichende Versorgung aller Organe des Körpers sicherzustellen. Insulin steuert sowohl in der Resorptions- wie der Postresorptionsphase als Schlüsselhormon den Austausch und die Verteilung von Substraten. Glukagon, Kortisol, Katecholamine und das Wachstumshormon spielen eine wesentliche Rülle fur den Energiestoffwechsel in Zeiten eines akuten Glukosebedarfs, wie er bei Arbeitsbelastung, im Streß oder als Reaktion auf eine Hypoglykämie vorkommt. Wichtigste Organe für die Aufrechterhaltung der Energiehomöostase sind die Leber und die Niere auf Grund ihrer besonderen Fähigkeit, Glukose zu produzieren; das Gehirn, da es von Glukose als seinem wesentlichen Energiesubstrat abhängig ist; die Muskulatur und das Fettgewebe auf Grund ihrer Fähigkeit, auf Insulin zu reagieren und Glukose in Form von Glykogen und Fett zu speichern (s. Shulmann et al. 1997; Tungermann u. Möhler 1980).
