Blood Sugar Log

Keep every blood sugar reading on one printable page

The blood sugar log is a one-page printable for anyone monitoring their blood glucose. Each row is a single reading, and the columns hold the date, the time of day, a before-meal value, an after-meal value, and a notes column for anything that matters — meals, exercise, medication or how you felt.

Print a fresh sheet at the start of each week, keep it by the meter or in a folder, and fill it in by hand as you test. A clear paper record is easy to hand to a nurse or doctor at your next appointment.

Choose mmol/L or mg/dL for the column headers, and print in A4 or US Letter.

Why use a printable blood sugar log?

Meter memory and phone apps are useful, but a printed log gives you something different — a single view of the week that you can annotate freely and share without screens. Use it for:

• spotting patterns between before-meal and after-meal readings
• noticing how particular meals or activities affect your numbers
• a tidy record to bring to GP, nurse or specialist appointments
• keeping a backup if your meter or app loses data
• tracking trends over weeks when you stack the sheets in a folder

Writing each reading down by hand also makes you pause and reflect on the number, which is part of good day-to-day management.

What you can customise

• Page title: default "Blood Sugar Log" or rename to suit you
• Name / Week-of line: turn the labelled line under the heading on or off
• Row count: 12 to 28 rows — fewer rows leave more height per reading, more rows cover a longer stretch
• Unit: mmol/L or mg/dL, printed in the before-meal and after-meal column headers
• Columns: Date, Time, Before meal, After meal, Notes
• Paper size: A4 or US Letter PDF

Notes and limitations

• This is a printable worksheet, not a fillable PDF or a medical device. You hand-write the readings, which keeps it universal and means no health data is stored anywhere.
• It does not replace advice from a healthcare professional — bring it to your appointments rather than self-diagnosing from it.
• The notes column is narrow by design; use short phrases like "after walk" or "missed dose".
• Print at 100% scale so the columns line up neatly.

How the columns work

Date and Time

Write the day and the time of the reading. Consistent timing — for example, first thing in the morning — makes the numbers easier to compare across days.

Before meal and After meal

Record the value before eating and the value a set time afterwards. Seeing the two side by side shows how a meal affected your level.

Notes

Anything the row does not capture — what you ate, exercise, medication, illness, or how you felt at the time.
