The normal range for blood sugar, specifically fasting blood glucose, is typically between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L) according to the World Health Organization (WHO).
Here's a more detailed breakdown:
Understanding Blood Sugar Levels
Blood sugar levels are a critical indicator of overall health, particularly concerning diabetes and insulin resistance. Fasting blood glucose measures your blood sugar after an overnight fast (at least 8 hours of no eating).
Normal Blood Sugar Range (Fasting)
- Normal: 70 mg/dL to 100 mg/dL (3.9 mmol/L to 5.6 mmol/L) - This range indicates healthy blood sugar regulation.
- Prediabetes: 100 mg/dL to 125 mg/dL (5.6 mmol/L to 6.9 mmol/L) - This suggests impaired glucose tolerance. Lifestyle changes and monitoring are recommended. According to the World Health Organization (WHO), when fasting blood glucose is in this range, changes in lifestyle and monitoring glycemia are recommended.
- Diabetes: 126 mg/dL (7.0 mmol/L) or higher - This typically indicates diabetes. Confirmatory testing is generally required.
| Category | mg/dL | mmol/L | Implication | Recommendation |
|---|---|---|---|---|
| Normal | 70-100 | 3.9-5.6 | Healthy blood sugar regulation | Maintain healthy lifestyle |
| Prediabetes | 100-125 | 5.6-6.9 | Impaired glucose tolerance | Lifestyle changes, monitoring glycemia |
| Diabetes | 126+ | 7.0+ | Possible diabetes | Confirmatory testing, medical consultation |
Importance of Monitoring
Regular monitoring of blood sugar levels is crucial, especially for individuals at risk of developing diabetes. Understanding the normal range helps in early detection and management.
