what is a normal level of glucose in the blood

Normal blood glucose levels vary depending on whether you are fasting or have recently eaten. Here are the general guidelines:

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

These values are for adults without diabetes. If you have diabetes, your target ranges may differ, and you should follow your healthcare provider's recommendations.

Condition Blood Glucose Level (mg/dL)

Normal (Fasting) 70–99
Prediabetes 100–125
Diabetes 126 or higher

Always consult your doctor for personalized advice.
