Standard Blood Sugar Levels Chart
| Test Type | Normal Range | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting Blood Sugar | 70–99 mg/dL | 100–125 mg/dL | 126+ mg/dL |
| Blood Sugar After Eating (2 Hours) | Below 140 mg/dL | 140–199 mg/dL | 200+ mg/dL |
| HbA1c | Below 5.7% | 5.7%–6.4% | 6.5%+ |
The fasting blood sugar normal range is measured after at least 8 hours without food. It is one of the most commonly used tests to diagnose diabetes and evaluate metabolic health.
The blood sugar levels after eating test measures how effectively the body processes glucose following meals. High post-meal sugar levels may indicate insulin resistance or impaired glucose tolerance.
The HbA1c test reflects average blood sugar levels over the previous 2–3 months. This test is extremely useful for long-term diabetes monitoring.
Why These Numbers Matter
Maintaining healthy glucose levels reduces the risk of:
- Type 2 diabetes
- Cardiovascular disease
- Stroke
- Kidney problems
- Nerve damage
- Obesity-related complications
Even small increases in fasting blood sugar can significantly increase long-term health risks.
long-term diabetes monitoring.
Morning Blood Sugar Spikes
Many people experience elevated morning sugar levels due to hormonal changes, stress hormones, or late-night eating habits. This phenomenon is often referred to as the “dawn effect.”
Stress and Blood Sugar
Stress triggers the release of cortisol and adrenaline, which can increase blood sugar levels. Chronic stress management is therefore essential for maintaining healthy glucose balance.
