Blood sugar: long-term value - Informative


The measurement of the actual blood glucose levels is very important in diabetes mellitus.

The importance of blood glucose

  • The blood sugar level states - as the name suggests - how much glucose is in the blood. Measured from the venous blood, as happens in a blood sample, the acute value should not exceed 100-110 mg / dl in healthy and sober people before. If you measure it with a Stix from z. B. fingertip, it should be slightly higher.
  • The glucose content of the body is regulated by various hormones. Insulin ensures that the blood sugar level drops and the glucose is absorbed and used in the cells, eg, as after a meal. Glucagon is, however, free glucose in the bloodstream by nutrients are removed from storage in the cells. Both hormones are produced in the pancreas.
  • When it comes to low concentrations in the blood can be up to coma and cravings subsequent cold sweats, confusion. Excessively high levels resulting long-term damage to vessels of the retina, kidneys and nerves. The latter occurs in the disease Diabetes mellitus. Type 1 is usually caused by an autoimmune process against the hormone-producing cells in childhood type 2. By a faulty insulin production and effect in mostly older, well-fed people

Acute values ​​and long-term value

  • The current blood sugar is determined several times a day with diabetes mellitus, otherwise only in the context of screening from the age of 35. These blood is taken from the fingertip or vein.
  • The current blood sugar levels but says naturally requires only the current situation. In diabetics, it is very important to know the long-term values ​​in order to know whether the drug therapy strikes suffizient or the drugs were taken correctly.
  • The long-term value for the blood sugar level is HbA1c. If a longer time have prevailed in the blood high glucose concentrations, there is a non-enzymatic hitch of glucose to proteins in the hemoglobin of red blood cells - the HbA1c!
  • The value provides information about the last 3 months. He should be <6.5% of the total Hb in the ideal case. In diabetic patients, values ​​are below 7.5% still good.
