what should your blood sugar be fasting

Fasting blood sugar levels are an important indicator of your overall glucose control. 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

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