When you checked your glucose
before lunch, it was 90mg/dL and
rising. Before eating lunch, you took
enough insulin to cover the meal and
a little more since your trend arrow
was
.

90 minutes later, your current
glucose is 225mg/dL. The graph
shows that your glucose is still going
up, and so does the trend arrow
.
Don’t take a correction dose within
2 hours of your meal dose. This may
result in “insulin stacking” and low
glucose.
Consider what might be causing
your glucose to go up and what you
might do to prevent a high glucose.
For example:
• Has the insulin you took for your
meal reached its full eect?
• Check your glucose again later.
