what should be fasting blood sugar

Fasting blood sugar (glucose) levels are an important indicator of your metabolic health. Here are the general guidelines for fasting blood sugar levels:

• 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

Fasting blood sugar is typically measured after not eating or drinking (except water) for at least 8 hours. If your levels are consistently high, it may indicate insulin resistance or diabetes. Consult your healthcare provider for a proper diagnosis and management plan.
