Reading your sugar log before a doctor visit

Ten minutes with your log before the appointment turns a page of numbers into clear questions. What to look for, and what to bring.

A doctor’s visit is short. If you arrive having already looked through your readings, the time goes on decisions instead of on reading a notebook together. You do not need to interpret the numbers medically — just organise them.

1. Bring the whole log

Bring every reading since your last visit, not only the good ones — the difficult days are often the most useful. If you use a meter, bring it too, and check that its date and time are set correctly so its memory lines up with your notes.

2. Make sure every reading says when it was taken

A number means little without its label. For each reading, note whether it was fasting (first thing in the morning, before food), before a meal, after a meal (and how long after), at bedtime, or random. The BP & Sugar Tracker records this type with every sugar reading.

3. Look for patterns, not single numbers

  • Is one time of day usually higher or lower than the rest — mornings, for example?
  • Do the readings after certain meals stand out?
  • Were there days that looked very different? Note what was different: an illness, travel, a festival, a missed medicine, poor sleep, unusual exercise.

Write down what you notice in plain words. “Fasting readings were higher on most days this month” is more useful in the room than a page of figures.

4. List every low

For each low reading, or each time you felt the signs of low sugar, note the date and time, what you had eaten, what you were doing, and what you did about it. Mention them even if they were mild and you managed them yourself.

5. Be honest about medicines

Bring your current medicines (or their strips) and note any doses you missed or took at a different time. Do not change or stop a medicine yourself because of what the log shows — take the question to your doctor.

6. Write your questions down

  • What range should my readings be in at each time of day?
  • How often, and at what times, should I check?
  • What should I do if my sugar goes low?
  • When is my next HbA1c test due?
  • Is there anything you would like me to record differently?

The tracker’s doctor report puts the counts, averages and ranges for a period you choose on one printable page, which you can hand over at the start of the visit.
