is 120 blood sugar high

A blood sugar level of 120 mg/dL can be interpreted differently depending on when it was measured:

• Fasting Blood Sugar (before eating): A level of 120 mg/dL is considered prediabetes (normal is below 100 mg/dL, prediabetes is 100–125 mg/dL, and diabetes is 126 mg/dL or higher).
• Postprandial (after eating): A level of 120 mg/dL is generally considered normal (typically, post-meal levels should be below 140 mg/dL).

If your fasting blood sugar is consistently 120 mg/dL, it may indicate prediabetes, and you should consult a healthcare provider for further evaluation and management.
