is 120 glucose level high

A blood glucose level of 120 mg/dL can be considered high depending on when the measurement was taken:

• 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.
• Postprandial (After Eating): A blood sugar level of 120 mg/dL 1-2 hours after eating is generally considered normal.

If you consistently have fasting blood sugar levels around 120 mg/dL, it is advisable to consult a healthcare professional for further evaluation and potential testing, such as an A1C test, to assess your average blood sugar levels over the past 3 months.
