Why is one side of my belly bigger than the other?

During pregnancy, the pregnant mother's abdomen is a more sensitive area and it is also an area that we need to pay attention to at all times. Some pregnant women find that the two sides of their abdomen are not the same size, and of course they are concerned about the reason. So, what is the reason why one side of the abdomen is bigger than the other?

First, generally speaking, this phenomenon is normal. It may be that the fetus likes a certain part more and then stays there for a long time. If such a situation occurs and pregnant mothers cannot tell whether there is a problem, the best way is to go to the hospital for a B-ultrasound examination and have the doctor conduct an assessment. In this way, pregnant mothers will not worry too much about this matter and will not be too worried.

Second, this is also closely related to the mother’s sleeping posture. We all know that during pregnancy, it is best to sleep on the left side, which is good for the fetus in the belly and can effectively prevent the problem of the umbilical cord around the neck of the fetus. However, this posture will also make the fetus stay in one area in the belly, so the pregnant mother's abdomen will appear to be larger on one side and smaller on the other.

What is the standard size of a pregnant belly?

The expansion of the uterus during pregnancy is cyclical, mainly manifested by the rise of the uterine fundus and the increase of the fetal abdominal circumference. Therefore, the uterine height and fetal abdominal circumference are generally used to consider the abdominal size of pregnant women. In addition, the pregnancy period and baby's development can be inferred by accurately measuring the standard values ​​of uterine height and fetal abdominal circumference.

The general method of accurately measuring uterine height is to let the pregnant woman lie flat on the bed after urinating, and use a soft tape to accurately measure the distance from the center of the upper edge of the ischial tuberosity to the fundus of the uterus. Generally, it is measured once every 4 weeks starting from the 20th week of pregnancy, every 2 weeks from 28 to 35 weeks of pregnancy, and once a week after 36 weeks of pregnancy. The way to measure the fetal abdominal circumference is to accurately measure the length of the waist and abdomen around the navel. When measuring, make the lower part of the tape completely close to the body, but do not tighten the abdomen. From the matching uterine fundus height and fetal abdominal circumference data, it can be determined whether the size of the uterus is appropriate for the number of weeks of pregnancy.

Generally speaking, it is normal for one side of the abdomen to be larger than the other during pregnancy. For this situation, mothers must not be too anxious or lose their composure. Pay attention to rest and replenish nutrients well. During this period, mothers can do some prenatal education for their babies, such as music prenatal education, fitness exercise prenatal education, etc.
