High Fasting Blood Glucose: what it means
A Fasting Blood Glucose result above the normal range is considered high. Here is what a raised Fasting Blood Glucose can point to, and when it is worth discussing with a doctor.
Reference range: Normal 70–99 mg/dL fasting; prediabetes 100–125; diabetes ≥126
Understand your full resultWhat a high Fasting Blood Glucose can mean
- 100–125 mg/dL — impaired fasting glucose / prediabetes. Reversible in most patients with lifestyle change.
- ≥126 mg/dL on two occasions — meets diabetes diagnostic threshold.
- >250 mg/dL with symptoms — call your doctor today; risk of dehydration and acidosis.
- Stress, infection, steroid medication — transient elevation without true diabetes.
When to discuss with a doctor
Fasting glucose 100–125 mg/dL once is worth repeating; persistent values in this range need a primary-care visit to discuss lifestyle and possibly an HbA1c. A reading ≥126 mg/dL with symptoms (excessive thirst, frequent urination, weight loss) warrants prompt evaluation. Mediora.AI plots your fasting trajectory alongside HbA1c so the pattern is obvious.
