Since the summer travel season is approaching, I thought I would pass along a few words I have found useful to have over the years. You never know when you're in a foreign country and you need to buy glucose/dextrose tablets for treating hypos. This list is not all-encompassing, only those I've managed to save over the years. If anyone has any others in other languages to add, please share them!
German: Traubenzucker (Note: German-made dextrose tabs are sold elsewhere in Central and Eastern Europe, so the word may also work in places like Slovenia, Poland, etc.)
Swedish: druvsocker, dextros
U.K.: In spite of speaking the same language, if you visit a chemist (pharmacy) in the U.K., I found asking for dextrose tabs worked, while asking glucose tabs got me strange looks from the pharmacist.
