You Are Not Your Blood Sugar Numbers

A great many people with diabetes describe a reading as "good" or "bad", and by extension themselves. That framing is understandable and it makes management measurably harder.

A reading is a measurement, not a moral outcome. Blood sugar responds to sleep, stress, illness, medicines, hormones, the time of day and what you did yesterday, as well as to what you ate. Treating every number as a report on your discipline means you are being graded on things you did not control.

What guilt actually does

• It makes people test less, because the number feels like judgement — and less information makes management worse.
• It produces over-correction: skipping the next meal, taking extra insulin, exercising to punish rather than to help.
• It gets in the way of asking for help, because a high result feels like something to hide from your doctor.
• It is a route into burnout, which a third to a half of people with diabetes experience over any 18 months.

A different way to read a number

Try replacing "I was bad today" with a question: what was different? Late dinner, poor sleep, a stressful day, a missed dose, an unusual meal. Sometimes the answer is nothing identifiable, and that is a real and normal answer too.

Your doctor needs the honest numbers, including the ones you dislike. A log edited by shame leads to the wrong treatment decisions.
