is 120 glucose high

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

• Fasting Blood Sugar: A fasting blood sugar level of 120 mg/dL is higher than the normal range (70-99 mg/dL) and may indicate prediabetes or diabetes.
• Post-Meal (Postprandial): A blood sugar level of 120 mg/dL 2 hours after eating is generally within the normal range (less than 140 mg/dL).

Key Points:

• Normal Fasting Glucose: 70-99 mg/dL
• Prediabetes (Fasting): 100-125 mg/dL
• Diabetes (Fasting): 126 mg/dL or higher

If you consistently have fasting blood sugar levels of 120 mg/dL, it is advisable to consult a healthcare professional for further evaluation.
