what should my fasting blood glucose be

Fasting blood glucose levels are an important indicator of your metabolic health. Here are the general guidelines:

• Normal: 70–99 mg/dL (3.9–5.5 mmol/L)
• Prediabetes: 100–125 mg/dL (5.6–6.9 mmol/L)
• Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests

It's important to note that these ranges may vary slightly depending on the laboratory or healthcare provider. If your fasting blood glucose is consistently outside the normal range, consult your healthcare provider for further evaluation and management.
