Glucose and metabolites of carbohydrate metabolism are the main sources in provision of energy of an organism.

The glycemia is a concentration of glucose or sugar in blood. The value of the glycemic index can vary depending on: time of day, meal, age, sex and other features of the person.

To learn what level of glucose in blood, it is necessary to make blood test.

To learn normal value of level of sugar in blood, measurement needs to be taken in the morning and before a breakfast.

Disturbance of a glycemia on an empty stomach

Normal level of sugar in blood varies within 3.3-5.5 mmol/l.

When the metabolism in an organism is broken, cells of fabrics cease to acquire correctly glucose, and it begins to collect in blood. The warning bell has to work when glucose level in blood on an empty stomach is from 5.6 to 6.9 mmol/l.

These figures mean the abnormal level of glucose in blood and a prediabetic state. The diagnosis a diabetes mellitus is not made yet, but already precedes to a disease. In these cases change in a way of life (weight reduction, the balanced food and daily exercise stresses) is necessary. It can be enough to control a situation and even to prevent development of diabetes.

Tell about diabetes when glucose level in blood is higher than 7.0 mmol/l. In this case, if not to begin appropriate treatment, then the diabetic coma can arise at any time.

How to measure glucose level in blood

At healthy people measurement of level of glucose in blood usually joins in any blood test or urine. Especially if it is about the people having obesity 50 years or for which the high pressure or a hypercholesterolemia is diagnosed are more senior. In all cases blood samples and urine have to be received on an empty stomach. 

If the diabetes mellitus is already diagnosed for patients, they have to start measurement of level of glucose in blood every morning before a breakfast. The glucose meter is for this purpose used. It is the device into which the test strip impregnated with a blood drop, taken after a puncture on a hand finger is entered.

Other tests, such as oral glyukozotolerantny test or glikozilirovanny hemoglobin, are applied at patients with diabetes or pregnant women with risk of development of a gestational diabetes mellitus.
