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

The normal range for blood sugar levels in mg/dL is considered to be between 70 and 100. This range represents a healthy fasting blood glucose level, which is critical for maintaining overall metabolic functions and preventing conditions like hypoglycemia and hyperglycemia.

When glucose levels fall below 70 mg/dL, it can indicate hypoglycemia, which can lead to symptoms such as dizziness, confusion, and in severe cases, loss of consciousness. Conversely, blood sugar levels above 100 mg/dL may signal issues like insulin resistance or diabetes, particularly if readings are consistently elevated.

The value of 70 to 100 mg/dL is well-established in medical guidelines, making it an important benchmark for healthcare professionals diagnosing and managing blood sugar abnormalities. Understanding this range is essential for individuals with conditions that affect blood sugar levels, as well as for the general population in maintaining good health practices.
