Changes in belly size during pregnancy and their causes
Pregnancy is a very special experience in every woman\’s life. It means that future mothers need to endure many physical and psychological changes. Changes in belly size during pregnancy are one of the most obvious changes during pregnancy. During pregnancy, a pregnant woman\’s belly will gradually increase in size over time. This article will introduce in detail the changes in belly size during pregnancy and the causes from several aspects.
1. Belly changes in early pregnancy
The early pregnancy period generally refers to the first three months of pregnancy. This period is called the most important period of fetal organ development. At this time, the baby\’s body is in a period of rapid development. However, the belly generally does not become significantly larger during this period. Therefore, the belly does not always change significantly, except for a vague increase in waist size. This may be partly because the baby is very small and cannot be clearly assessed from the belly on ultrasound.
As the fetus grows, the size of the belly will begin to change.
2. Belly changes in the second trimester
The second trimester generally refers to the fourth to sixth month of pregnancy. At this time, fetal development has entered a stable period and the belly will grow faster. In the second trimester, the baby begins to grow gradually, and the belly will become significantly larger at this time. In the second trimester, the best way to estimate your baby\’s size is from a cross-section of your belly and intra-abdominal fluid. The subcutaneous fat in the belly is rejected and the uterus begins to expand, which is why the belly area becomes larger in the second trimester.
3. Belly changes in late pregnancy
The third trimester generally refers to the seventh to ninth month of pregnancy. At this time, the fetus is growing faster and its size is also increasing. At this time, the belly has become very big, almost the same size as the baby. Moreover, although the baby can be seen moving in many pregnant women, the fetus in the third trimester has become too large and has no room to move. At this time, the belly has swollen like a ball, and it will cause a lot of physical discomfort to pregnant women.
4. Why does the belly get bigger during pregnancy
There are many reasons why your belly keeps getting bigger during pregnancy. One of the most important reasons is changes in female hormones. Rising hormone levels during pregnancy promote the expansion of the uterus, giving the baby more room to grow. One of the secondary reasons is the growth and development of the fetus. As the pregnancy continues, the fetus continues to grow, which is also the reason why the belly gradually becomes larger.
Summary
During pregnancy, the size of the belly changes significantly. The belly will not become significantly larger in the first trimester, but will gradually become larger in the second trimester. In the third trimester, the belly has become very large, the fetus is already very large, and there is not much room for growth. These changes are due to hormone levels and the growth and development of the fetus. It is very helpful for every expectant mother to understand the changes in belly size and the causes, which can help them better cope with the changes during pregnancy.
