Blood sugar level, also known as blood glucose level, refers to the concentration of glucose in your blood. Glucose is a primary source of energy for your body's cells and is derived from the foods you eat. Maintaining a healthy blood sugar level is crucial for overall health, especially for individuals with diabetes or prediabetes.
Normal Blood Sugar Levels:
- Fasting (before eating): 70–99 mg/dL
- 2 hours after eating: Less than 140 mg/dL
Blood Sugar Levels in Diabetes:
- Fasting (before eating): 126 mg/dL or higher indicates diabetes.
- 2 hours after eating: 200 mg/dL or higher indicates diabetes.
Blood Sugar Levels in Prediabetes:
