what is fasting sugar

Fasting sugar, also known as fasting blood glucose (FBG), refers to the level of glucose in your blood after not eating or drinking anything (except water) for at least 8 hours. It is a common test used to diagnose prediabetes, diabetes, or to monitor blood sugar control in people with diabetes.

Normal Fasting Blood Sugar Levels:

• Normal: Less than 100 mg/dL
• Prediabetes: 100 to 125 mg/dL
• Diabetes: 126 mg/dL or higher on two separate tests

Why is it important?

Fasting blood sugar levels provide insight into how well your body manages glucose without the influence of recent food intake. High fasting sugar levels may indicate insulin resistance or diabetes, while low levels could suggest hypoglycemia.

If your fasting sugar levels are consistently high, consult a healthcare provider for further evaluation and management.
