Normal Blood Sugar Level Chart (Fasting, After Meal & HbA1c)

One of the most common questions for anyone with diabetes — or worried about it — is simple: what is a normal blood sugar level? This guide gives clear target ranges for fasting, after meals, and HbA1c, plus what the numbers mean.

বাংলা সারাংশ: খালি পেটে স্বাভাবিক সুগার সাধারণত ৪–৬ mmol/L, খাবারের ২ ঘণ্টা পর ৮ mmol/L-এর নিচে থাকা ভালো। আপনার ব্যক্তিগত লক্ষ্য চিকিৎসকের সাথে ঠিক করে নিন।

Note: Targets vary by person (age, pregnancy, other illness, medication). Use this chart as a general guide and confirm your personal targets with your doctor.

Blood sugar target chart (general guide)

When testedNormal (no diabetes)Common target with diabetes
Fasting / before meal4.0–5.4 mmol/L (70–99 mg/dL)4.0–7.0 mmol/L (80–130 mg/dL)
2 hours after a mealunder 7.8 mmol/L (140 mg/dL)under 8.5–10 mmol/L (per your doctor)
HbA1c (3-month average)below 5.7%often around 7% or lower

mmol/L is the unit most commonly used in Bangladesh; mg/dL is shown for reference.

What the numbers mean

  • HbA1c shows your average sugar over ~3 months — the best measure of long-term control. Many aim for around 7%, but your doctor sets your target.
  • Fasting sugar is measured first thing in the morning before eating.
  • Post-meal (2-hour) shows how your body handles food.

How to check accurately at home

The only way to know your own numbers is to test with a reliable meter and good technique.

Accu-Chek Active glucometer for checking blood sugar at home in Bangladesh

Wash and dry your hands, use an unexpired strip, apply a full drop of blood, and record the result with the time and whether it was before or after a meal. Keep a glucometer and test strips at home so you can track trends, not just single readings.

When to see a doctor urgently

  • Very high readings with symptoms (excess thirst, frequent urination, drowsiness).
  • Very low readings (below 4 mmol/L) with sweating, shaking, or confusion — treat low sugar quickly with fast carbs and seek help.
  • Consistently high numbers despite medication.

Frequently asked questions

What is a dangerous blood sugar level?
Persistently very high readings, or lows under 4 mmol/L with symptoms, need prompt medical attention. Discuss your personal danger zones with your doctor.

How often should I test?
It depends on your treatment. People on insulin usually test more often. Your doctor will advise a schedule.

Is fasting or HbA1c more important?
Both matter. HbA1c shows long-term control; daily readings show what's happening right now.
