Great idea Holger. That’ll come in handy for many People including myself. Thanks!
Gibt es auch eine Liste für die neuen österreichischen Mitglieder, und bzw die neuen Mitglieder, die auf der ‘richtigen’ Seite des Röstigrabens wohnen? 
@Lila: leider erfahre ich von neuen Mitgliedern auch nur durch deren Befreundung mit der Botschaft. Du könntest aber eine Botschaft für Östereich gründen. Frag doch mal Manny danach. Grüße, Holger
Das war ja nur ein Witz, vielleicht nicht ganz erfolgreich. Tut mir leid!
Haha this is awesome… I didn’t know there were that many German people on this site… I moved to America from Germany three years ago… but this is a really good idea… a lot of new words 
New terms: Apotheke, Cholesterin, Gewebeflüssigkeit, Herz-Kreislauf-Erkrankung, Kapillarflüssigkeit, Stechhilfe, Zertifizierter Diabetesberater.
Very good idea.
Very nice! Thank you!
One small correction:
Teststreifen = test stripe = stripe
In U.S. English, they are written: “test strip” – strip, with no “e” at the end.
@JeanV: Thank you! I corrected that.
Is “Zuckerkrankheit” considered hopelessly old fashioned and out of date now?
i.e. is it painful for a young German to hear, maybe like in the US when we hear Wilfred Brimley say DIABEEETIS?
I actually like the German words, they made much more sense to me than the latin- and greek-derived crud they taught us in English class. Kohlenstuff, Waserstuff and Sauerstuff is way better than carbon, hydrogen and oxygen.
@Tim: Zuckerkrankeit is great. I have added it. It is still used but as you have already pointed out it is old fashioned.
LOL, DIABEEETIS is painful. We learn Oxford English at school which is a nice theory. Then in places like Yorkshire we will start to recognize that local accents rule the world.
New terms: Arzt, Ärztliche Bescheinigung, Basalrate, Temporäre Basalrate, Pennadel, Vorfüllung
