Blood sugar log

A landscape log for writing down glucose readings through the day and the medicine or food around them. It records what you measure and does not interpret it. It is meant to be taken to appointments with your care team.

What prints

The sheet is landscape, with the heading Blood Sugar Log and lines for your name and the month. The table starts with a Date column. Next come three shaded groups labeled Breakfast, Lunch and Dinner, and each group has two columns: Before and After. Then there is a Bedtime column, a Medicine or insulin column, and a wide column headed Notes (food, activity).

Beneath the table one line reminds you to write each reading in the units your meter shows, either mg/dL or mmol/L, and to share the log with your care team. It also says plainly that the log does not interpret readings.

The settings

  • Heading. A custom title of up to 40 characters; empty keeps the default.
  • Log. Choose "Blood sugar".
  • Rows. From 10 to 31, and the page opens at 20. Use one row per day.

The Morning and evening toggle and the Reading log type menu belong to other logs and do not change this sheet.

Filling it in

Each row is a day. Not everyone checks at every meal, so leave boxes blank when you did not test; a blank is better than a guess. Write only what the meter displayed, in the units it uses. Do not convert between mg/dL and mmol/L on the sheet.

Use the Medicine or insulin column for the name or dose and the time, in whatever shorthand your care team already uses. The Notes column is for context: a large dinner, a long walk, an illness, a missed meal. Short phrases are enough.

The CDC and NIDDK pages above explain what blood sugar monitoring is and why some people do it, and your own care team will tell you when and how often to check. This page does not set any schedule.

Worked example: a few days in March

Your month line says March. On the 3rd you write the number from the meter in Breakfast Before, the number two hours later in Breakfast After, and skip lunch checks. At Dinner Before you record the number and in Notes write "pasta, 20 min walk after". In the Medicine column you write the name and time you took it. On the 4th you test only at bedtime because you were traveling, and you note "on the road".

After two weeks you have 14 rows with a mix of filled and blank boxes. You do not total, average or circle anything. You staple the sheet to your meter's case and bring it to the next visit, where your clinician can read it alongside any meter download.

Good habits for record-keeping

  • Write at the time of the test. Numbers recalled later tend to drift.
  • Keep the page with your meter so the two travel together.
  • If you change units or meters, note the date in the Notes column.
  • Do not use this page to decide what to eat or take. Follow the plan your care team gave you.

The blood pressure log has a similar layout for another home reading. Meals are easier to describe with the meal planner, and the workout log records the activity you mention in Notes.
