Diabetes management: daily care, the ABCs, and CGM
Key takeaways
- Think ABCs: A1C (often below 7%), Blood pressure (often below 130/80), Cholesterol, and Stop smoking.
- With a CGM, a common goal is more than 70% of the time between 70 and 180 mg/dL, and less than 4% below 70.
- Daily habits — meals, movement, sleep, stress — matter as much as medicines.
- Get regular eye, foot, kidney, and dental checks.
The ABCs of diabetes
| What | Common target for many adults | |
|---|---|---|
| A | A1C | Below 7% (individualized) |
| B | Blood pressure | Below 130/80 mm Hg |
| C | Cholesterol | Set with your doctor; many people with diabetes take a statin |
| S | Stop smoking | Smoke-free |
Targets are personal — your care team may set higher or lower goals depending on age, other conditions, and low-blood-sugar risk.
Monitoring blood sugar
Fingerstick meter
Check as often as your plan says — commonly fasting, before meals, 1–2 hours after meals, and at bedtime. Write down the time and context.
Continuous glucose monitor (CGM)
A small sensor worn on the arm or belly measures glucose every few minutes and shows trends on your phone. International consensus targets for most adults with type 1 or type 2 diabetes:
| CGM metric | Goal |
|---|---|
| Time in range (70–180 mg/dL) | More than 70% (about 17 hours a day) |
| Time below 70 mg/dL | Less than 4% |
| Time below 54 mg/dL | Less than 1% |
| Time above 250 mg/dL | Less than 5% |
Daily habits
- Eat regular, balanced meals using the plate method.
- Move — 150 minutes a week, and break up long sitting; short walks after meals help.
- Sleep 7–9 hours; poor sleep raises glucose.
- Manage stress — stress hormones raise blood sugar. Cardivo's HRV and stress readings can show how your body responds.
- Take medicines as prescribed.
Sick-day basics
Illness can push glucose up. Keep drinking fluids, check glucose more often, and follow your sick-day plan (including ketone testing if you have type 1). Call your doctor if you can't keep fluids down, and call 911 for vomiting with high glucose, trouble breathing, or confusion.
Regular checkups
- A1C every 3–6 months
- Dilated eye exam, kidney tests (urine albumin and eGFR), and a foot exam at least yearly
- Dental checkups and recommended vaccines
- Diabetes self-management education and support — proven to improve outcomes
Cardivo brings glucose logs, blood pressure, heart rate, HRV, and mood into one timeline and a shareable PDF — the "B" and the stress side of diabetes care in one place.

Frequently asked questions
What are the ABCs of diabetes?
A1C, Blood pressure, Cholesterol, and Stop smoking — the four areas that most reduce the risk of diabetes complications when kept on target.
What is a good time in range on a CGM?
For most adults with diabetes, the international consensus goal is more than 70% of readings between 70 and 180 mg/dL, with less than 4% below 70 mg/dL.
How often should I check my blood sugar?
It depends on your treatment. People on insulin often check several times a day or use a CGM; others may check less often. Follow your care team's plan.
