Blood sugar level, also known as blood glucose level, refers to the concentration of glucose present in your blood. Glucose is a primary source of energy for your body's cells and is derived from the foods you eat.
- Normal Range: For most people, a normal fasting blood sugar level is between 70-99 mg/dL.
- Prediabetes: Fasting blood sugar levels between 100-125 mg/dL may indicate prediabetes.
- Diabetes: A fasting blood sugar level of 126 mg/dL or higher typically indicates diabetes.
Blood sugar levels can be measured using a blood glucose meter or through lab tests like the A1C test, which provides an average blood sugar level over the past 2-3 months.
Maintaining healthy blood sugar levels is crucial for overall health, as consistently high or low levels can lead to serious complications.
