    Hyponatriämie: Gefährlicher Wassermangel und Natriummangel erklärt

    Best quote from 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.

    Frequently Asked 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.

    Seriously I haven’t even explored this app fully yet but from using it the last few days I am so impressed... BeFreed is on a different level from any other learning app I have used. This makes it ultra engaging and can actually improve your concentration which is great for all the doom scrollers!

    @ladyInfinity

    I bought BeFreed exactly 23 days ago, and I have used it every single day since. It has completely embedded itself into my daily workflow and learning habit.

    @jayallen

    The truth is, the app has exceeded all my expectations. I can ask it to generate audio on any topic, whatever it may be, and the result is impressive. My professional field is a specialization in psychotherapy and it is multidisciplinary; however, the answers are very accurate.

    @Raguipa

    What I appreciate most is how much it's reduced my scrolling – I'm spending less time searching and more time absorbing information. The combination of full audiobooks, podcasts, the learning plans are brilliant.

    @colonyofcreatorsNGO

    I have been a PhotoReading Accelerated Learning Instructor for the past 24 years... books and reading and learning are my thing, and BeFreed has done a great job in providing an innovative approach to disseminating and delivering information in an easy to consume way.

    @BeFreed user

    It is not just a book summary app, I have used the 'fun reading' option and it's a much better summary and way to grasp ideas the traditional way, that alone is worth this deal.

    @austinakon

    I love this app. Used it for several days and I cannot stop listening. Such a great way to start.

    @jcrules328

    I really like the program; I have already tested it for around one month, and I feel that it's an amazing gem. It works so well because I can use BeFreed to create my own topics, and the voice is so good with unlimited choice of narrations.

    @DanielCZ

    I love the fact that I can get useful, condensed, information and ideas in a 8 - 15 minute podcast style audio. I'm not a general fan of podcasts because of all the fluff, but this cuts through all that.

    @BeFreed user

    I am finishing up my doctorate, and have to read a lot of unfamiliar material... With BeFreed, you simply enter a prompt, and the app finds source material for you and generates an audio podcast. I find the process in BeFreed to be more streamlined than NotebookLM.

    @Brad

    I often search YouTube for something to listen to whilst making breakfast, when I'm out walking, commuting, etc, and BeFreed has provided an even more targeted approach, without the adverts and the fluff!

    @BeFreed user

    The absolute best part about this platform is its versatility. There is literally no subject that is off-topic. It handles whatever you throw at it... It is rare to find an learning tool with zero limitations that actually delivers on its promises.

    @jayallen

    BeFreed is fantastic. The user-friendly design means I spend less time navigating and more time learning. The mix of audiobooks, podcasts, and learning plans is a genius combo that has completely changed my daily routine.

    @BeFreed user

    At the start I needed a while to understand how to create podcasts in italian language and boom! It is so great! I can ask to explain every argument and it does so well and so smartly!

    @matteo77

    BeFreed has become my daily app for audio books tools... What I like the most is the way you put your text and come with an audio that you can listen on the go.
