Diabetes
Blood sugar monitor
Single readings tell you very little; the pattern tells you almost everything. Log yours, see the chart, and take it to your diabetes team rather than trying to remember.
No readings yet
Add a reading above. The chart, time in range and averages appear once there is something to plot — and none of it leaves this device.
Getting an accurate reading
- Wash and dry your hands — fruit or sugar on a finger gives a falsely high reading.
- Use the side of the fingertip, not the pad, and rotate fingers.
- Check the strips are in date and stored in their pot with the lid closed.
- Record what was happening: before or after food, illness, steroids, exercise, alcohol.
- If a reading does not match how you feel, wash your hands and repeat it.
Treating a hypo
- 15–20 g of fast-acting carbohydrate: 4–5 glucose tablets, 150 ml fruit juice or ordinary cola, or 3–4 teaspoons of sugar in water.
- Wait 15 minutes and retest. Repeat if still below 4 mmol/L (72 mg/dL).
- Once back in range, eat something starchy — a sandwich, fruit, or your next meal if it is due.
- Do not drive until you are in range and have waited 45 minutes.
- If someone is drowsy, confused, fitting or unconscious, do not put anything in their mouth — this is an emergency, call for help.
This is a log, not a diagnosis, and it will never tell you to change a dose. Bring it to your appointments — and see diabetes nutrition for how food, timing and portions move these numbers.
