is 143 a high blood sugar

A blood sugar level of 143 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 a reasonable range (typically <180 mg/dL for people with diabetes).

When to Be Concerned:

• If fasting blood sugar consistently exceeds 125 mg/dL, it may indicate diabetes.
• If post-meal blood sugar consistently exceeds 180 mg/dL, it may suggest poor blood sugar control.

Always consult your healthcare provider for a proper diagnosis and management plan.
