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 typically rise. A level of 140 mg/dL 1–2 hours after a meal is generally within the target range for most people with diabetes.
When to Be Concerned:
- If your fasting blood sugar is consistently 140 mg/dL or higher, it may indicate poor blood sugar control and should be discussed with a healthcare provider.
- For non-diabetic individuals, a fasting blood sugar of 140 mg/dL is a sign of impaired glucose tolerance or diabetes.
Always consult your doctor for personalized advice and further testing if needed.
