Function

Function

  • Glucose is a common medical analyte measured in blood samples. Eating or fasting prior to taking a blood sample has an effect on the result. A high fasting glucose blood sugar level may be a sign of prediabetes or diabetes mellitus.


Glucose levels

Glucose Levels


Normal blood sugars

Normal Blood Sugars

  • A normal fasting (no food for eight hours) blood sugar level is between 70 and 99 mg/dL

  • A normal blood sugar level two hours after eating is less than 140 mg/dL


Pre diabetes

Pre-diabetes

  • A fasting blood glucose in between 100-125 mg/dL

  • You are at high risk of developing diabetes. You can prevent or delay diabetes by increasing physical activity, eating healthful foods, and maintaining or losing weight

  • Pre-diabetes is also called impaired fasting glucose (IFG)


Diabetes

Diabetes

  • Two consecutive fasting blood glucose tests that are equal to or greater than 126 mg/dL


Sources and absorption

Sources and absorption

  • Most dietary carbohydrates contain glucose

  • Liver cell glycogen can be converted to glucose and returned to the blood when insulin is low or absent

  • muscle cell glycogen is not returned to the blood because of a lack of enzymes
