What is the normal range for fasting blood glucose levels?

The normal range for fasting blood glucose levels is indeed recognized as 70 to 100 mg/dL. This range indicates the concentration of glucose in the blood after fasting for at least eight hours. Levels within this range suggest that the body's insulin response and glucose metabolism are functioning properly.

A level below 70 mg/dL can indicate hypoglycemia, which is lower than the normal range and may lead to symptoms of low blood sugar. Conversely, levels above 100 mg/dL but below 126 mg/dL are considered to be indicative of prediabetes, while levels at or above 126 mg/dL indicate diabetes.

Understanding these values is important for diagnosing and managing conditions such as diabetes and for monitoring blood sugar levels in at-risk patients.
