is 128 high for blood sugar

A blood sugar level of 128 mg/dL can be considered high depending on the context:

• Fasting Blood Sugar: If this reading is taken after fasting (not eating for at least 8 hours), it is slightly elevated. Normal fasting blood sugar levels are typically between 70-99 mg/dL. A level of 100-125 mg/dL indicates prediabetes, and 126 mg/dL or higher suggests diabetes.
• Post-Meal Blood Sugar: If this reading is taken 1-2 hours after eating, it is within the normal range. Post-meal blood sugar levels should generally be below 140 mg/dL.

If you consistently see readings around 128 mg/dL, especially while fasting, it’s important to consult a healthcare provider for further evaluation and potential testing, such as an A1C test, which provides an average blood sugar level over the past 2-3 months.
