How often should you check your blood sugar? Which finger gives the most accurate reading? Is the meter you’re using actually trustworthy?
These are questions people living with diabetes ask quietly — sometimes for years — without ever getting clear answers. And the answers matter, because how well you manage diabetes at home depends almost entirely on how well you understand your own numbers.
Here are five things worth knowing.
Â
1. Self-monitoring isn’t optional — it’s how you stay in control
Blood sugar moves all day. It rises after meals, falls between them, and shifts with stress, sleep, exercise, and illness. A clinic test once every three months can’t capture any of that.
Self-monitoring at home is how you see what your body is actually doing — and the value isn’t in any single number. It’s in the patterns those numbers reveal: which meals push you up, which habits bring you down, which warning signs are early enough to act on.
Done well, self-monitoring isn’t about anxiety. It’s about confidence.

2. How often you check depends on your treatment
There’s no universal answer to “how often should I test?” It depends on your medication, your stage of diabetes, and your healthcare provider’s guidance. As a general guide:
- Most people on insulin check 2–4 times a day, often before meals and at bedtime
- People on oral medication typically check 1–2 times daily, or as advised by their doctor
- Newly diagnosed or adjusting medication? You may need to check more frequently for a few weeks to establish patterns
If you’re not sure, ask your doctor or pharmacist for a schedule that fits your plan. Consistency matters more than frequency.

3. Your meter has to be accurate — or none of it matters
Here’s the part most people skip: a meter that gives wrong readings is worse than no meter at all. It can lead to too much insulin, the wrong meal, or a missed warning sign.
The global standard for accuracy is ISO 15197:2013 — the test every quality meter must pass to prove its readings match laboratory values. Cheaper, unbranded meters often don’t meet this standard.
This is why ISN Medical distributes Accu-Chek Instant, made by Roche, the global leader in blood glucose monitoring. Accu-Chek Instant is ISO-certified, features a visual range indicator that shows you instantly whether you’re in target, and is built to perform reliably in Nigerian conditions — heat, humidity, travel, and all.
When your meter is dependable, every other habit on this list works.

4. Track your numbers — your phone makes it easy
Reading your blood sugar is only step one. Step two is tracking it over time, so you and your doctor can see the patterns.
Handwritten logbooks work, but they’re easy to forget and easy to lose. Modern meters like Accu-Chek Instant pair seamlessly with the MySugr app, which logs every reading automatically, calculates your averages, and shows your time-in-range at a glance.
At your next consultation, you can show your doctor weeks of clean, organised data instead of a half-full notebook. Better data leads to better decisions.

5. You don’t have to do it alone
Living with diabetes is a daily practice — and like any practice, it’s easier with a community.
The LiveWell Club is ISN Medical’s community for Nigerians living with diabetes (and the families who care for them). Members get monthly tips, expert sessions, recipe ideas, and real conversations from people on the same journey.
The right meter is essential. The right people make it sustainable.
