Reading your own glucose log

A glucose log is more useful when you can read it yourself. Reading is not the same as interpreting: you are looking for patterns to bring to your provider, not conclusions to act on alone.

Group by context, not by date

Fasting numbers belong with fasting numbers. Post-breakfast belongs with post-breakfast. Comparing a fasting reading to an after-dinner reading tells you nothing.

Look for the shape, not the outlier

One high reading after a birthday cake is a data point, not a trend. Four out of seven mornings drifting upward is a trend. Your provider is interested in the second.

Note the two-word context

"Late dinner". "Slept badly". "Walked after". A number with two words attached is far more useful than a number alone — both for you and at your appointment.

What you are not doing

You are not deciding whether your numbers are acceptable, and you are definitely not adjusting medication. Ranges and treatment belong to your care team. If a pattern worries you, that is exactly what the "add a question" button is for.

Bringing it to a visit

Show the trend chart, name the pattern in one sentence, and ask a specific question. "My fasting numbers have crept up over the last two weeks — does that change anything?" gets you further than handing over a full log and hoping.
