Many pregnant women can read in his medical records data about the weight of the fruit, but few are wondering about how to calculate it.Meanwhile, there are quite a number of ways to do this, however, is not always the result will be very accurate.
The first and easiest way to calculate the weight of the fruit - keep track of their own weight.However, there is the likelihood that a pregnant woman gains weight, not because the child grows, but because of the edema, overeating and other factors.But if the set weight is strictly individual schedule, you can simply take advantage of special tables of the main indicators of pregnancy for weeks and did not suffer the question: "How to calculate the weight of the child?"But in calculating the "rule of thumb" it should also take into account that the "excess" weight of the body gives a large number of circulating blood.So the accuracy of this method is very, very questionable.
second method of how to calculate the weight of the child, is also quite simple and suitable for self-application, though it requires some skill.Estimated fetal weight is calculated by a simple formula: multiply the height and volume of the uterine fundus of the stomach.Typically, these data can be found at the gynecologist during the next visit, but can be determined independently.The volume of the stomach is measured in centimeters at the level of the navel, but with the height of the uterine fundus is not so easy.The idea is that until the last weeks of pregnancy, this figure coincides with a period in weeks, but this is not always the case.In fact, I find the bottom of the uterus is not too difficult, especially after 12 weeks.Easier still, ask to teach to determine the uterine bottom.Thus, the distance from the pubic symphysis to the uterine fundus is the required value.The above formula provides for accurate measurement of very average values, which may also be incorrect due to features of a constitution and pregnancy.There are other formulas, more accurate, so ask your midwife about how to calculate the weight of the baby, is not out of place at the next visit.Who knows, maybe, an expert tells non-standard way.
Finally, not to be tormented with questions about how to calculate the exact weight of the child, you can refer to the ultrasound, they will help to calculate the weight of the fetus with acceptable accuracy.In order to determine this figure is several dimensions: the size of the head, the length of the arm from shoulder to elbow, thigh length, the amount of the child's abdomen.On the basis of these figures the doctor calculates the weight of the fetus.Many modern phones even do it automatically after measurement and display information about the alleged pregnancy, in accordance with the indicators.This method of how to calculate the weight of the baby, is not always accurate.It depends on many factors: the accuracy and precision of measurements of the position of the fetus in the uterus, and so on. D. In the later stages of calculation errors may be up to half a kilogram!Even ultrasound a few hours before birth can not calculate the weight that will be at birth.
In fact, no one method does not give a completely correct result.But the accuracy of ultrasound or counting by measuring the height of the uterus and the volume of the stomach is acceptable to assess a child's development.And the rest of moms just need to listen to yourself.
