Hiya, Yep stress can indeed affect your BS readings, it helps if you do 'know' what is stressing you? reduce it to as low as you can, retest few hours later and see if made a difference? It can be a bit like when you go for a BP check at hosp [white coat syndrome] it goes up whilst you're there and goes down later after left the hospital.. Happens to me all the time! go to hospital n whoop up it goes! :shock: they usually tell me to sit chill read a book first as result. Do you feel stressed?? Anna.x
