what is blood sugar reading

A blood sugar reading, also known as blood glucose level, measures the amount of glucose present in your blood at a given time. Glucose is a type of sugar that comes from the food you eat and is your body's primary source of energy. Blood sugar readings are typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L).

Normal Blood Sugar Ranges:

• Fasting (before eating): 70–99 mg/dL (3.9–5.5 mmol/L)
• 2 hours after eating: Less than 140 mg/dL (7.8 mmol/L)

Blood Sugar Levels for Diabetes Diagnosis:

• Fasting: 126 mg/dL (7.0 mmol/L) or higher
• 2 hours after eating: 200 mg/dL (11.1 mmol/L) or higher

Regular monitoring of blood sugar levels is crucial for managing diabetes and preventing complications. If you have concerns about your blood sugar levels, consult a healthcare professional for personalized advice.
