A blood sugar level of 138 mg/dL can be considered high depending on when the measurement was taken:
- Fasting Blood Sugar: If measured after fasting (not eating for at least 8 hours), a level of 138 mg/dL is higher than the normal range (70–99 mg/dL) and may indicate prediabetes or diabetes.
- Post-Meal Blood Sugar: If measured 1–2 hours after eating, 138 mg/dL is generally within a normal range (typically less than 140 mg/dL for non-diabetic individuals).
For a definitive diagnosis, consult your healthcare provider. They may recommend additional tests like the A1C test, which provides an average blood sugar level over the past 2–3 months.
