what's a blood sugar level

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.
