    Meilleure citation de Hyponatriämie: Gefährlicher Wassermangel und Natriummangel erklärt

    “

    Die Hyponatriämie ist meistens ein Wasserproblem: Der Körper behält zu viel Wasser zurück oder trinkt mehr, als die Niere ausscheiden kann, wodurch das Natrium gefährlich verdünnt wird.

    Foire aux questions

    Unter einer Hyponatriämie versteht man ein gefährliches Absinken der Natriumkonzentration im Serum auf einen Wert von unter 135 Millimol pro Liter. Wie Lena im Podcast erklärt, handelt es sich dabei nicht nur um ein bisschen zu wenig Salz, sondern um eine ernsthafte Störung des Elektrolythaushalts. Natrium fungiert hierbei als wichtigster Taktgeber für die gesamte Flüssigkeitsverteilung im menschlichen Körper, weshalb ein Mangel das gesamte System belasten kann.

    Eli weist darauf hin, dass bei fast 14 % der Läufer des Boston-Marathons nach dem Rennen eine Hyponatriämie festgestellt wurde. Das Problem entsteht oft durch gut gemeinte Hydrierung, wenn Sportler bei extremer Belastung literweise Wasser trinken, ohne auf den Salzhaushalt zu achten. Diese übermäßige Wasserzufuhr kann die Natriumkonzentration so stark senken, dass der Zustand für die Läufer trotz ihrer sportlichen Ambitionen lebensgefährlich wird.

    Obwohl man oft weniger davon hört als von Magnesiummangel, ist die Hyponatriämie im Krankenhaus extrem verbreitet. Laut Lena tritt dieser Zustand bei etwa 15 bis 30 % aller Patienten auf, was bedeutet, dass fast jeder dritte Krankenhauspatient betroffen sein kann. Diese hohe Zahl verdeutlicht, dass ein gestörter Natriumhaushalt kein Nischenthema für Extremsportler ist, sondern eine fundamentale Rolle in der medizinischen Versorgung und für die Gesundheit spielt.
