Is 257 glucose reading is normal?

A blood glucose reading of 257 mg/dL is considered significantly high. Normal blood sugar levels for a non-diabetic person usually range between 70-110 mg/dL (3.9-6.1 mmol/L) after fasting. Anything above this range is generally considered elevated and requires attention.

For individuals with diabetes, the target blood sugar levels may vary based on their individual circumstances and management plan. However, generally speaking, a reading of 257 mg/dL would be considered high and may require immediate medical intervention.

It is important to consult a healthcare professional if you have concerns about your blood sugar levels, as they can provide personalized guidance and assistance in managing your diabetes.
