What is a Healthy Fasting Blood Sugar Level?
Fasting blood sugar (FBS) is the level of glucose in your blood after not eating for at least 8 hours. It is a key indicator of how well your body regulates blood sugar and can help detect early signs of diabetes or insulin resistance.
Healthy Fasting Blood Sugar Levels by Category
| Category | Fasting Blood Sugar (mg/dL) | Fasting Blood Sugar (mmol/L) |
|---|---|---|
| Normal (Non-Diabetic) | 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 or higher | 7.0 mmol/L or higher |
📌 For children with diabetes, fasting blood sugar targets may range from 80–130 mg/dL (4.4–7.2 mmol/L), depending on individual needs.
Why is Fasting Blood Sugar Important?
✅ Indicates overall blood sugar control – Helps assess how well your body processes glucose overnight.
✅ Detects prediabetes early – Can identify insulin resistance before diabetes develops.
✅ Guides diabetes management – Helps track progress for those managing blood sugar levels.
✅ Prevents long-term complications – Stable levels reduce the risk of heart disease, kidney issues, and nerve damage.
How to Maintain a Healthy Fasting Blood Sugar Level
✔ Eat a balanced diet – Include fiber, protein, and healthy fats in meals.
✔ Avoid late-night snacks – Give your body time to regulate glucose levels overnight.
✔ Stay physically active – Regular exercise improves insulin sensitivity.
✔ Manage stress – High stress levels can raise blood sugar.
✔ Get quality sleep – Poor sleep affects glucose metabolism.
✔ Monitor your blood sugar – Use a glucose meter or continuous glucose monitor (CGM) to track levels.
Final Thoughts
Maintaining a healthy fasting blood sugar level is key to preventing diabetes and supporting overall well-being. If your levels are consistently high, consult a healthcare provider to discuss potential lifestyle changes or medical interventions.
