What is the normal blood sugar range?

The normal blood sugar range for a healthy individual, particularly when measured in a fasting state, is generally considered to be between 70 and 100 mg/dL. However, values can vary slightly, and some sources accept a range up to 120 mg/dL after meals. Therefore, the choice indicating a normal blood sugar range of 80-120 mg/dL is appropriate as it encompasses the accepted normal levels for fasting blood glucose and postprandial values. This range allows for variations that can occur after eating, acknowledging that blood sugar levels can naturally rise after consumption. Understanding these ranges is critical for effectively monitoring and managing blood glucose levels in clinical settings.
