• Your Dexcom ONE readings do now match your
symptoms.
Example: you do not feel
right but your readings show
your glucose is in target
range. Wash your hands
thoroughly and use your BG
meter. If the BG meter value
matches your symptoms,
use the BG meter value to
treat.
5.2 When to watch and wait
There are times when you should
not treat at all, just watch and
wait.
Stacking insulin: Do not stack
insulin by taking doses too close
together. Wait at least 2 hours
between doses so you do not accidentally force
your glucose down too low. Sometimes, it is best to
watch and wait.
