What is the normal range for blood sugar levels in mg/dL?

The correct choice regarding the normal range for blood sugar levels is based on established medical guidelines. In general, a fasting blood glucose level is considered normal if it falls between 70 and 100 mg/dL. This range indicates that the body is effectively managing blood sugar levels, which is crucial for maintaining good health and preventing conditions such as diabetes.

The upper limit of 100 mg/dL in this range signifies a healthy threshold for glucose metabolism, as levels above this may indicate impaired glucose tolerance or prediabetes, especially if they are consistently observed. This is why the range of 70 to 110 is significant; it effectively captures the normal span while allowing for some minor variations that may occur naturally throughout the day.

Understanding this range is vital for healthcare providers and those monitoring their own blood sugar levels, particularly individuals with diabetes. Knowledge of what constitutes a normal range helps inform decisions regarding dietary choices, medication administration, and overall health management.
