Enter your fasting blood sugar reading to screen for normal levels, prediabetes, or diabetes.
Fasting blood glucose is measured after abstaining from eating for at least 8 hours. The chart below uses guidelines from the American Diabetes Association.
| Fasting Blood Sugar (mg/dL) | Approx. mmol/L | Description |
|---|---|---|
| < 70 mg/dL | < 3.9 | Low (Hypoglycaemia) |
| 70 – 99 mg/dL | 3.9 – 5.5 | Normal |
| 100 – 125 mg/dL | 5.6 – 6.9 | Prediabetes |
| ≥ 126 mg/dL | ≥ 7.0 | Diabetes |
Fasting blood glucose levels between 70 and 99 mg/dL are considered normal. A level between 100 and 125 mg/dL means you have impaired fasting glucose — a type of prediabetes — which significantly increases your risk of developing type 2 diabetes.
A level greater than 126 mg/dL usually indicates diabetes (confirmed by two separate tests). For a comprehensive overview, see the EMG Diabetes section.
Blood sugar too low. Can cause dizziness, sweating, confusion. Requires immediate attention if symptoms present.
Healthy fasting range. Maintain with balanced nutrition, regular exercise, and stress management.
Impaired fasting glucose. Fully reversible with a 5–7% weight loss and 150 min/week of moderate exercise.
Consistent with diabetes. Requires medical evaluation, lifestyle modification, and possibly medication.
