Circumference of the abdomen by weeks of pregnancy

For a common man in the state of pregnancy is the appearance of a woman - her belly increases. So, to control pregnancy, the dimensions of the abdominal circumference are very important, which are determined by the weeks. But the figure itself will not play an important role if the measurement is not carried out regularly. After all, it is very important dynamics, according to which an experienced doctor can judge the course of pregnancy.

How correctly to measure a circumference of a stomach or belly?

Every pregnant woman knows how to measure. A woman must be in a horizontal position - this measurement will be the most accurate. After all, otherwise, with the existing overstretch of the anterior abdominal wall or problems with the spine, the result will turn out to be incorrect. A normal centimeter tape wraps around the abdomen in the navel at the front and at the maximum bend of the waist from behind.

In addition to the circumference of the abdomen in the second trimester, the height of the standing of the uterus begins to measure - by the end of pregnancy, the approximate weight of the fetus is calculated from it. After 36 weeks, this indicator does not change, the uterus increases no longer in height, but only in breadth.

An important influence on the results of the measurement is the physique of a woman - if she is too thin or obese, then, of course, the figures will be far from the stipulated norms.

Norms the circumference of the pregnant belly by week

The tummy begins to grow from about 10 weeks gestation. But then its parameters are not so important and the volume is not measured. With the progression of pregnancy, around the end of the second trimester, the abdominal circumference should have the following dimensions (with an average build and no excess weight):

• 32-34 weeks - 80-90 cm;
• 38-39 weeks - 90-95 cm;
• 40-42 weeks - 95-105 cm.

So, special attention to the growing tummy begins to be given after 32 weeks. If by this date his circumference is less than 80 cm with a normal physique of a pregnant woman, then this can talk about the lack of water and the lag in the development of the baby.

If, according to the gynecologist's observations, the abdomen's circumference increases at regular intervals, and at the next visit has not changed - this is an occasion to urgently undergo ultrasound - perhaps, the fetus's condition is critical.

By the end of pregnancy the abdomen volume, most often does not exceed 95-105 cm. A sharp deviation from this figure to the large side indicates a multiple pregnancy, polyhydramnios or transverse position of the fetus.
