is 137 a high blood sugar

A blood sugar level of 137 mg/dL can be considered high depending on the context:

• Fasting Blood Sugar: A fasting blood sugar level of 137 mg/dL is higher than the normal range (70–99 mg/dL) and may indicate prediabetes or diabetes.
• Post-Meal Blood Sugar: After eating, blood sugar levels can rise temporarily. A level of 137 mg/dL 1–2 hours after a meal is generally within the acceptable range (less than 180 mg/dL for most people with diabetes).

If you consistently see blood sugar levels of 137 mg/dL or higher, especially when fasting, it’s important to consult a healthcare professional for further evaluation and potential testing (e.g., A1C test).
