A member asked:
Why does it say water is allowed during the 8-12 hour fasting for the 2 hour glucose test? will that not cause a false lower blood sugar?
A doctor has provided 1 answer
Sugar stays same: Drining water does not affect level of blood sugar because it is filtered out by kidneys and does not affect glucose that is consumed as part of the glucose tolerance test.
