What is on the log
- Fasting: the reading when you wake up, before you eat.
- Breakfast, lunch and dinner: the time you started eating, your reading after the meal, and what you ate.
- Notes: a walk after dinner, a bad night, a sick day, a snack at bedtime.
- Your targets: a box at the top for the numbers your clinic gave you, and whether they want the check 1 or 2 hours after eating.
How to fill it in
- Write your clinic's targets in the box at the top first. Guidelines differ a little (see blood sugar targets); your clinic's numbers are the ones that count.
- Write the time you took the first bite, then check at 1 or 2 hours after that, as your clinic told you (see when to check after eating).
- Write every reading, including the high ones. The log is for your care team to adjust your plan; a high number is information, not a grade.
Why a written log
ACOG tells patients to keep a record of blood sugar levels and bring it to each prenatal visit, and says the log can also be kept in a phone app and emailed to the ob-gyn.1 A log that shows the time of each meal next to each reading lets your team see which meal is the problem.
Questions
Is this log free?
Yes. Download and print as many copies as you need. No sign-up.
What do I write if I forgot to check?
Leave the box empty or write “missed”. An honest gap is more useful to your clinic than a guess.
mg/dL or mmol/L?
Use the unit on your meter. The log has no printed unit so it works for both.
