is 148 high blood sugar

A blood sugar level of 148 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 higher than the normal range (70–99 mg/dL) and may indicate prediabetes or diabetes.
• Post-Meal Blood Sugar: If this reading is taken 1–2 hours after eating, it is slightly elevated but may still be within an acceptable range for some individuals. However, consistently high post-meal readings could indicate poor blood sugar control.

When to Consult a Doctor:

• If your fasting blood sugar is consistently above 126 mg/dL, it may indicate diabetes.
• If your post-meal blood sugar is consistently above 180 mg/dL, it may suggest poor glucose management.

Always consult a healthcare professional for personalized advice and further testing, such as an A1C test, which provides an average blood sugar level over the past 2–3 months.
