The name "glucose" is a monosaccharide with a sweet taste and related to aldhexoses. In living organisms, it is contained both in free form and as an ester of phosphoric acid.
This substance is actively used in medicine, where it acts as a nutrient component or an integral part of blood substitutes, as well as anti-shock solutions. But, as they say, everything is good in moderation. Exceeding such an indicator as the
normal level of glucose in the blood, which lasts a long time, can lead to unpleasant consequences.
Diabetes
Surely everyone has heard about diabetes. The main link in the pathogenesis of this disease is the lack of a hormone responsible for the utilization of glucose in tissues. As a result, the named monosaccharide accumulates in the blood, and cells and tissues suffer from a lack of energy. That is why it is so important that the norm of blood glucose is always observed .
When taking a sample from a finger, if before that the patient did not eat anything, the indicator should vary between 3.3-5.5 mmol / L. When the blood
glucose norm
is exceeded, but has not yet reached 6.1 mmol / L, this condition is called prediabetes. Otherwise, it can be called a "violation of tolerance." In cases where venous blood was drawn, the values are shifted by about 12%.
Since the diagnosis of changes in sugar level is important in the diagnosis of diabetes mellitus, now in any doctor’s office you can test. The determination of glucose in the blood does not take much time. It is also worth noting that, according to the recommendations of the World Health Organization, all people whose age exceeds 40 years old should take this analysis every 3 years. This will not only allow timely diagnosis of the disease, but also prevent it from starting. This fact is extremely important because it is very difficult to deal with diabetes complications.
Analysis accuracy
But is the rapid blood test accurate? Glucose cannot fool a doctor. Undoubtedly, laboratory tests are more accurate. You cannot make a diagnosis of diabetes mellitus only if the blood glucose level is exceeded. In addition, it should be remembered that there are some factors that may affect the results of the study. They are:
- Drinking alcohol on the eve of blood donation.
- The presence of acute diseases.
- Incorrect preparation for passing the analysis.
If none of these factors occurs in your case, but the results of the study indicate prediabetes, do not despair! Violation of carbohydrate metabolism is still quite insignificant. Get rid of excess weight, take care of proper nutrition. It is necessary to reduce food intake to the level of 1700 kcal per day. Forget about cakes, sweets, pastries and other tasty, but high-calorie foods. Go in for sports. Swimming and water aerobics are great. Do not forget to consult with specialists. Diabetes can be prevented! That is why you should not neglect blood tests for sugar!
