Most often with such research as the glucose tolerance test, or as it is also called "sugar curve"face pregnant women. However, it can appoint and ladies are not in the position, and men. The analysis is necessary in order to find out what the level of fasting blood glucose and after exercise.
Who and when is prescribed a study
The need to find out how the body treats the sugar load in pregnant women arises in those cases if the urine tests are not perfect, the expectant mother’s weight increases too quickly or the pressure rises. The sugar curve during pregnancy, the norm of which may be slightly modified, is plotted several times to accurately determine the response of the body. However, it is recommended to conduct this study and those who have a suspicion of diabetes or this diagnosis has already been confirmed. It is also prescribed for women with an established diagnosis. "polycystic ovaries".
How is the analysis performed?
The study can not be called simple, because it requires special training and is carried out in several stages – the only way to achieve that a reliable sugar curve is obtained. The results of the analysis should be interpreted only by a doctor or medical consultant, taking into account your health condition, weight, lifestyle, age and related problems.
Preparation for the study
Notice blood test "sugar curve" may be unreliable if a woman takes it during critical days. In addition, the patient’s behavior influences the results of the study. Thus, when implementing this complex analysis, it is necessary to be at rest, physical exercise, smoking, and stress are prohibited.
Interpretation of results
When evaluating the obtained indicators, it is important to consider a number of factors that influence the amount of glucose in the blood. So, make a diagnosis "diabetes" considering only the results of this test is impossible. Indeed, the indicators may be affected by forced bed rest, previous research, various infectious diseases, problems with the gastrointestinal tract, which are characterized by impaired sugar absorption or malignant tumors. Also, the results of the study can distort the failure to comply with the established rules for blood sampling or taking illegal drugs. When consumed caffeine, adrenaline, morphine, diuretics, belonging to the thiazide series, "Difenina", psychotropic drugs or antidepressants, the sugar curve will be unreliable.
If you are taking 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, in the range of 5.5-6 (and, accordingly, 6.1–7 – from the vein) indicate a prediabetes state, and they indicate possible impairment of glucose tolerance.
Laboratories should know if the result of an analysis performed on an empty stomach exceeds 7.8 for capillary and 11.1 for venous blood, then it is prohibited to conduct a glucose sensitivity test. In this case, it can cause hyperglycemic coma. If the indicators initially exceed the norm, then it makes no sense to find out what the sugar curve will be. The results will be clear.
If during the study you received indicators that indicate problems, it is better to retake the blood. At the same time, it is necessary to observe all conditions very carefully: avoid stress and physical exertion on the day of blood collection, exclude alcohol and medications a day before the analysis. Treatment can be prescribed only if both analyzes have shown not very good results.
By the way, if a woman is in an interesting position, then it is better to interpret the results obtained with a gynecologist and endocrinologist, only this specialist can assess whether you have a normal sugar curve during pregnancy. The norm for women in an interesting position may be slightly different. However, this will not be said in the laboratory. Establish whether there are problems, can only a specialist who knows all the features of the body of the future mother.
It should be noted that diabetes mellitus is not the only problem that can be determined using the glucose-assay test. Another deviation from the norm is a decrease in the amount of sugar in the studied blood after exercise. This disease is called hypoglycemia, it necessarily requires treatment. After all, it is accompanied by a number of problems such as constant weakness, fatigue, irritability.
