Understanding Blood Sugar Ranges for Diabetes: What's Normal?

For non-diabetic adults, a normal fasting blood sugar level ranges from 70–99 mg/dL (3.9–5.5 mmol/L).

Target Ranges for Diabetic Adults

Individual targets vary based on circumstances and treatment goals, but general guidelines recommend:

• Before meals (fasting): 80–130 mg/dL (4.4–7.2 mmol/L)
• 1–2 hours after meals (postprandial): Less than 180 mg/dL (10 mmol/L)

These are general guidelines; a healthcare professional may adjust targets based on individual needs and diabetes management goals. Regular monitoring and consultation with a provider are essential for optimal control.
