Fourteen days of continuous glucose, asked one question: how does it vary with the time of day. The answer is a clear daily shape. The question it raises — what causes that shape — needs data this fortnight does not contain, and the last section says exactly which.
Questions
Each was written down before its analysis was run, so what was asked stays
separable from what was found.
“How does my glucose vary as a function of time of day?”
Strongly patterned by the clock. His glucose is lowest around 05:00 and highest around 11:00 — a swing of about 107 mg/dL, and his waking day averages 49 mg/dL above his night. He falls steadily through the night with no early-morning rise, then climbs sharply after 08:00. It survives dropping either of the two sensors. What it cannot show is why — nothing in this export records a meal.
One page: the shape of his day, three ways of measuring it, what was done to break it, the overall level, and one thin lead reported with its fragility.
