is 120 a high blood sugar

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, 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: 100–125 mg/dL (fasting)
• Diabetes: 126 mg/dL or higher (fasting)

If your fasting blood sugar is consistently 120 mg/dL, consult a healthcare provider for further evaluation.
