is blood sugar of 120 high

A blood sugar level of 120 mg/dL can be considered high or normal depending on the context:

• Fasting Blood Sugar: If measured after fasting (not eating for at least 8 hours), a level of 120 mg/dL is higher than the normal range (70–99 mg/dL) and may indicate prediabetes or diabetes.
• Post-Meal Blood Sugar: If measured 1–2 hours after eating, a level of 120 mg/dL is generally within the normal range (less than 140 mg/dL).

Key Points:

• Normal Fasting Blood Sugar: 70–99 mg/dL
• Prediabetes (Fasting): 100–125 mg/dL
• Diabetes (Fasting): 126 mg/dL or higher

If you consistently see fasting blood sugar levels of 120 mg/dL, consult a healthcare professional for further evaluation.
