A number on the meter, but when was it taken? Write the time beside your blood sugar reading. Blood sugar can follow different patterns across the day, so the time gives the number useful context.
Flashcard
Why write the time beside a blood sugar reading?
Answer: Blood sugar can change in patterns across the day. The time helps you understand the situation around that number when you look back later.
For example, a reading at bedtime may be part of a different daily pattern from one taken in the morning. A helpful home record includes both the blood sugar level and the time of day.
You may also note relevant details, such as carbohydrate food, activity, or anything unusual that day, including stress or illness. These details add context, but they do not explain the cause by themselves.
It is like writing the time beside a temperature reading: the time helps describe the situation, but does not give the full reason for the result.

Takeaway: A blood sugar number is easier to look back on when its time is recorded.
