What It Measures
The concentration of glucose (sugar) in the blood after 8-12 hours of fasting.
Fasting blood glucose measures the sugar level in your blood after an overnight fast. It is a primary screening tool for diabetes and metabolic health.
Current Value
What High Means
Elevated fasting glucose indicates insulin resistance, prediabetes (100-125 mg/dL), or diabetes (≥126 mg/dL). Chronically high glucose damages blood vessels, nerves, kidneys, and eyes.
Possible Symptoms
Increased thirst, frequent urination, fatigue, blurred vision, slow wound healing
What Low Means
Low glucose (hypoglycemia, <70 mg/dL) can cause shakiness, confusion, dizziness, and in severe cases, loss of consciousness. May indicate excess insulin or adrenal issues.
Possible Symptoms
Shakiness, sweating, rapid heartbeat, anxiety, hunger, confusion
Risk Factors
Type 2 diabetes, cardiovascular disease, kidney disease, neuropathy, retinopathy
