is 140 blood sugar high

A blood sugar level of 140 mg/dL can be considered high depending on the context:

• Fasting Blood Sugar: A fasting blood sugar level of 140 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 140 mg/dL 1–2 hours after a meal is generally within the target range for most people with diabetes.

Key Points:

• Normal Range: 70–99 mg/dL (fasting)
• Prediabetes: 100–125 mg/dL (fasting)
• Diabetes: 126 mg/dL or higher (fasting)

If you consistently experience blood sugar levels of 140 mg/dL or higher, consult a healthcare professional for further evaluation and management.
