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 Blood Sugar Levels:
- Fasting (before meals): 70–99 mg/dL
- 2 hours after eating: Less than 140 mg/dL
Blood Sugar Levels in Diabetes:
- Fasting (before meals): 126 mg/dL or higher indicates diabetes.
- 2 hours after eating: 200 mg/dL or higher indicates diabetes.
Monitoring Blood Sugar:
- Home Monitoring: Use a glucometer to check blood sugar levels at home.
- A1C Test: Measures average blood sugar levels over the past 2–3 months. An A1C level of 6.5% or higher indicates diabetes.
Maintaining healthy blood sugar levels is crucial for preventing complications related to diabetes, such as heart disease, kidney damage, and nerve damage.
