as i diabetic myself i can give you some advice...diabetics sometimes get low blood sugars which means that their body doesn't have enough sugar in their blood stream...they should be carrying around something sweet like a juice packet or candy bar...anything with alot of carbohydrates (which is on the nutritional facts) that is easy to drink or chew. my friends usually have something in their purse or car for me just in case. diabetics should be carrying around a device called glucagon, it may be called differently but it is a sugar injection that if they pass out someone will have to give to them...oh and if they are passed out do the shot and then call 911. Diabetics also get high blood sugars which means, well they have too much sugar. We also carry around insulin which makes the blood sugar go down. If they pass out for no reason they have a tester or checker whatever you like to call it....please test them before doing anything cause you may not know if their blood sugar is high or low, get someone else to call 911
i know that was alot maybe even too much but i just want to help and there is alot more if your interested...i hope that helps and i hope i didn't scare you with all of that
