The presence or absence of sugar in the urine is an "indicator" of the level of glucose in the blood. Normally, sugar in the urine during pregnancy is absent, but it happens that during the next analysis, experts still find it. But at the same time warn: a single case of the appearance of sugar in the urine during the bearing of a baby is not a reason for panic and is not an obligatory sign of diabetes. Furthermore, often sugar in the urine during pregnancy (if its level is raised slightly) can be regarded as a physiological phenomenon.
So, sugar in the urine appears due to some phenomena that occur in the body. Initially, glucose always penetrates through the renal filter into the primary urine, however, due to its active absorption, it does not enter the secondary urine, that is, the final urine (the one that eventually becomes the "raw material" for analysis). If the amount of glucose rises and the kidneys do not cope with its "absorption" in the blood, the excess glucose is released as sugar in the urine. It is known that during pregnancy the female organism works doubly: sometimes the kidneys simply can not process the synthesized amount of glucose.
You should also take into account the factor, that during the gestation of the baby the body triggers a special anti-insulin mechanism, through which so much glucose circulates in the blood, as the growing baby needs. If this mechanism works too "hard", producing an excessive amount of glucose, which is no longer needed by either the mother or the child, and with which the kidneys can not cope, it is excreted from the body, showing increased sugar in the urine during pregnancy. Most often this phenomenon is recorded in the third trimester of pregnancy.
Usually, a slight and short increase in sugar in the urine while waiting for the baby is not a threat to pregnancy or the fetus itself. But about the pathology you can say if the elevated sugar level is fixed repeatedly or the figures are excessively overestimated. In this case, it is necessary to conduct a blood test to determine the level of glucose - with such indicators there is a probability of the development (or already presence) of diabetes maternal.
The diabetes mellitus of pregnant women is indicated not only by increased sugar in the urine during pregnancy, there is this ailment and other very noticeable unpleasant symptoms. Among them: frequent urination, high blood pressure, repeated moniliasis infections of the vagina, and all this - against a background of increased appetite. The tendency to develop diabetes mellitus pregnant women are women at risk: a hereditary predisposition to this disease; pregnant women after the age of 30; overweight women; mothers, whose weight of the first children exceeded 4. 5 kg; who registered elevated sugar in the urine or non-perception of glucose before pregnancy.
To prevent the pathological increase of sugar in the urine during pregnancy, you can by following a set of rules. In addition to the need to regularly see a doctor, you must also follow a diet for pregnant women and follow the weight, adhere to the principles of a healthy lifestyle, perform physical exercises. At the first symptoms of the disease, immediately consult a doctor - timely response to the situation allows you to lower blood glucose (and hence sugar in the urine), thereby preventing any undesirable effects of diabetes in pregnant women.
