It can, especially if you ate the wrong thing. You should always follow your doctors instructions exactly.
it can however my dr also told me if i can make sure to go at least 8 hrs or more than it should be ok.
Well I only had rice an chicken. An by the time I go to do the test it will be 9hr since I last ate. Soo that should be ok???
I was told to fast for 8 hrs but every doctor is different
My doc told me to eat but don't drink anything but water.
I personally never could waomit I would eat toast and drink water. I feel really week and dizzy if I would wait 8 hours.
