What are normal glucose levels in mg/dL?

50-80
70-110
90-130
100-150

The correct answer is: 70-110

Normal glucose levels for a fasting state in healthy individuals typically range from 70 to 110 mg/dL. This range is critical as it reflects adequate glucose homeostasis in the body, which is essential for normal metabolic functions. When blood glucose levels are maintained within this range, it indicates that the body is effectively regulating glucose through insulin and other hormones. Glucose concentrations below or above this range can suggest various metabolic disorders. Levels below 70 mg/dL may indicate hypoglycemia, which can lead to symptoms such as dizziness, confusion, and even loss of consciousness. Conversely, levels above 110 mg/dL, especially when fasting, may indicate a risk for diabetes or prediabetic conditions as they suggest impaired glucose tolerance. The other ranges provided do not align with established clinical guidelines for normal glucose levels. The choice of 70-110 mg/dL is supported by numerous clinical studies and is widely accepted in medical practice, thus affirming its correctness in identifying normal glucose levels.
