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.
