Blood Glucose values as per WHO recommendation

Diabetes (diabetes mellitus), is a disease in which body doesn't make enough insulin or can't use it as well as it should. When there isn't enough insulin or cells stop responding to insulin, too much blood sugar stays in bloodstream. Over time, that can cause serious health problems, such as heart disease, vision loss, and kidney disease. To prevent or delay possible complications, patients can self-monitor their blood sugar now a days.

The expected values for normal fasting blood glucose concentration are between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L).

When fasting blood glucose is between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) changes in lifestyle and monitoring glycemia are recommended.

If fasting blood glucose is 126 mg/dL (7 mmol/L) or higher on two separate tests, diabetes is diagnosed.

An individual with low fasting blood glucose concentration (hypoglycemia) – below 70 mg/dL (3.9 mmol/L) – will experience dizziness, sweating, palpitations, blurred vision and other symptoms that have to be monitored.

Increased fasting blood glucose concentration (hyperglycemia) is an indicator of a higher risk to diabetes. An individual’s fasting blood plasma glucose (FPG) may be in the normal range because the individual is not diabetic or because of effective treatment with glucose-lowering medication in diabetics. Mean FPG at the national level is used as a proxy for both promotion of healthy diets and behaviours and, treatment of diabetes.
