Spotting Patterns, Not Single Readings
A single blood sugar reading is a photograph of one moment. Diabetes is managed on the film, not the photograph.
This matters because reacting to individual numbers produces worse control than reading patterns does. A high after dinner leads to a skipped breakfast, which leads to a low, which leads to over-treating it, and by the end of the week nothing is interpretable.
Three questions to ask of a week of readings
- Is it the same time of day? Highs clustered before breakfast point somewhere completely different from highs clustered after dinner.
- Is it the same direction? Consistently high, consistently low, or swinging widely between the two — these are three different problems.
- What else was going on? Sleep, illness, stress, a changed routine. A week of poor readings often has a week of poor sleep sitting behind it.
Test at consistent times so the readings are comparable. Four readings taken whenever you remembered cannot be lined up against each other; one reading taken at the same hour every day can.
Give a change two weeks. Whether it is a new medicine, a smaller rice portion or a post-meal walk, a few days is noise. Two weeks of readings at the same times is a signal you can act on.
