Sugar Curve - What Is It? Which indicators of the sugar curve are normal?

Most often, pregnant women face such a study as a glucose tolerance test, or as it is also called a "sugar curve." However, it can appoint to ladies not in position, and to men. The analysis is necessary in order to find out what the level of fasting blood glucose is after the load.

To whom and when the study is assigned

The need to find out how the body relates to the sugar load in pregnant women occurs in cases where urinalysis is not ideal, the future mother is too fast to increase weight or increase pressure. The sugar curve in pregnancy, the norm of which can be slightly changed, is constructed several times to find out exactly the reaction of the organism. However, it is recommended to carry out this study and those who have a suspicion of diabetes mellitus or this diagnosis has already been confirmed. It is also prescribed to women with an established diagnosis of "polycystic ovaries".

Even if you have relatives in your family who have diabetes, then you should periodically check the blood glucose level. After all, the timely identification of problems will make it possible to do only with preventive measures. For example, if the sugar curve has small deviations from the norm, it is important to control your weight, monitor your diet and exercise. In some cases this will be quite enough to prevent diabetes, but sometimes there is a reasonable need to use special medicines that will not allow it to develop.

How is the analysis done

The study can not be called simple, because it requires special training and is carried out in several stages - only in this way it is possible to achieve a reliable sugar curve. The results of the analysis should be interpreted only by a doctor or a medical consultant, taking into account your state of health, weight, lifestyle, age and attendant problems.

For the diagnosis, the blood is given several times. And in some laboratories it is taken from a finger, and others from a vein. Depending on what kind of blood is being studied, the resulting norms will also differ. The first study is performed strictly on an empty stomach. He must be preceded by a 12-hour fasting, during which you can use only ordinary water. However, it is important that the period of abstinence from drinks and food does not exceed 16 hours. After taking blood, the patient takes 75 grams of glucose dissolved in 200 ml of warm water or tea. Ideally, the analysis should then be performed every 30 minutes for at least two hours. But, as a rule, in laboratories simply make one more fence in 30-120 minutes after the use of a sweet liquid.

Preparation for research

If you are assigned to check the amount of glucose in the blood, then do not try to exclude all the carbohydrate-rich foods a few days before the study. This can lead to incorrect interpretation of the results. Preparation for the analysis is as follows. Three days before the trip to the laboratory, it is necessary to observe the habitual way of life and not change food preferences. But from the use of medication it is necessary to abstain, however, any temporary refusal of treatment should be coordinated with the doctor.

Note, the blood test "sugar curve" may be unreliable if the woman will take it during critical days. In addition, the patient's behavior influences the results of the study. So, in the implementation of this complex analysis must be in a calm state, physical activities, smoking, stress are prohibited.

Interpretation of results

When assessing the results, it is important to consider a number of factors that affect the amount of glucose in the blood. So, it is impossible to diagnose "diabetes mellitus" taking into account only the results of this test. After all, the indices can be influenced by the forced bed rest, preceding the study, various infectious diseases, gastrointestinal problems, which are characterized by impaired absorption of sugar or malignant tumors. Also, the results of the study may distort the failure to comply with established rules for blood sampling or the taking of illicit drugs. With the use of caffeine, adrenaline, morphine, diuretics related to the thiazide series, "Diphenine", psychotropic medications or antidepressants, the sugar curve will be unreliable.

Set norms

If you pass the test, the glucose level should not exceed 5.5 mmol / l for capillary blood and 6.1 for venous blood. Indicators for the material taken from the finger, within 5.5-6 (and, respectively, 6.1-7 - from the vein) indicate pre-diabetes, while talking about possible violations of glucose tolerance.

With higher results, we are already talking about serious problems with the pancreas, but it depends on her work what the sugar curve will be. The norm for the glucose level, which is determined after the specified time after the load, should not be more than 7.8 mmol / l, but under the condition of finger blood testing. If the indicator is within the range of 7,8-11,1, then it is a question of possible violations, and above 11,1 - about diabetes. When collecting venous blood, the indices should not exceed 8.6 mmol / l.

Laboratory staff should be aware if the result of the analysis performed on an empty stomach exceeds 7.8 for capillary and 11.1 for venous blood, then a glucose sensitivity test is prohibited. In this case, it can cause a hyperglycemic coma. If the indicators initially exceed the norm, then there is no sense in figuring out what the sugar curve will be. The results and so will be clear.

Possible deviations

If during the study you got indicators that indicate problems, then the blood should be retested. In this case, it is worth very carefully observe all the conditions: to avoid stress and physical exertion on the day of blood sampling, to exclude alcohol and medication the day before the analysis. Treatment can be prescribed only if both analyzes showed not too good results.

By the way, if a woman is in an interesting situation, then interpret the results better with a gynecologist-endocrinologist, only this specialist can assess whether you have a normal sugar curve in pregnancy. The norm for women in an interesting situation may be slightly different. However, this will not be said in the laboratory. To establish, whether there are no problems, only the expert who knows all features of work of an organism of the future mum can.

It should be noted that diabetes mellitus is not the only problem that can be identified with a glucose-assay test. Another deviation from the norm is a decrease in the amount of sugar in the blood under investigation after a load. This disease is called hypoglycemia, it necessarily requires treatment. After all, it is accompanied by a number of problems such as persistent weakness, increased fatigue, irritability.
