A glucometer is the cheapest, most powerful diabetes tool you own.
It tells you exactly how your body responded to that paratha, that walk, that stressful meeting. Used well, it teaches you more than a doctor visit can.
When to test
Frequency depends on your treatment:
- Diet/exercise only: 2-3 times a week, varying times
- Oral meds: Once a day, rotating fasting / pre-meal / post-meal
- Insulin: 3-4 times a day, before insulin doses + bedtime
- Pregnant with GDM: 4 times a day — fasting + 1 hour after each meal
Target ranges (most adults)
- Fasting / pre-meal: 80-130 mg/dL
- 2 hours after meal: under 180 mg/dL
- Bedtime: 100-140 mg/dL
Your doctor may adjust these based on age and conditions.
How to log usefully
A number without context is useless. Record:
- Time of day
- Reading (mg/dL)
- Before / after meal? How long after?
- What you ate (rough notes)
- Activity / stress / sleep notes
Patterns emerge after 2-3 weeks. You will spot the foods that spike you, the days that didn't. Take the log to your next doctor visit.
