Between meals, your current glucose
is 72mg/dL. The Glucose Going Low
message tells you that your glucose
is projected to be low within 15
minutes.
Think about what might be causing
your glucose to go low. Consider
eating a snack to stay within target.
Avoid taking insulin as this can
cause low glucose.

blood glucose test.

Before dinner, your current glucose
is 134mg/dL. The graph shows that
your glucose is going down and so
does the trend arrow
.
Consider what might be causing your
glucose to go down and what you
might do to prevent a low glucose.
For example:
• How much insulin should you take
before your meal?
• Since you see
, should you
consider taking a little less insulin?
