ok so last nite my 20 yrs old brother went upstairs to get a drink. a few seconds after he got up there we heard a huge noise..like something was gonna fall through the celling. we all ran upstairs and my bro passed out. he was really white(even his lips) couldnt talk and was out fro prolly 4 mins. we have a lot of diabetics in my family. my grandmother has a glucose tester here so my mmom used it this mornin and it came back 83.....is that high or low or wat?? wat should ur blood measure normally? does it matter male or female? should he see a doctor????
