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

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

For diabetic adults, the target blood sugar range may vary depending on individual circumstances and treatment goals, but in general, it is commonly recommended to maintain blood sugar levels:

- Before meals (fasting): between 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 target ranges are general guidelines and can be adjusted by a healthcare professional based on individual needs and their diabetes management goals. It's important for people with diabetes to regularly monitor their blood sugar levels and consult with their healthcare provider to determine the best target ranges and adjustments to their treatment plan.
