is blood sugar of 140 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 (2 hours after eating): A blood sugar level of 140 mg/dL is generally within the target range for most people with diabetes (typically less than 180 mg/dL).

If you consistently have blood sugar levels of 140 mg/dL or higher, especially when fasting, it is important to consult a healthcare professional for further evaluation and management.
