Women undergo many physical changes during pregnancy due to hormonal fluctuations and the need to accommodate a growing fetus.
Three trimesters of pregnancy
Human pregnancy lasts 280 days, or 40 weeks, and is divided into three trimesters. Each trimester lasts three months.
- The first trimester lasts from the last menstrual period to 13 weeks.
- The second trimester lasts 14-27 weeks.
- Followed by the third trimester, which lasts 28-42 weeks.
- Around 40 weeks, labor can begin. Preterm labor occurs before 37 weeks of gestation.
- Several developmental changes occur in the fetus during each trimester and continue until childbirth.
Changes in mother's body:
- Morning sickness subsides during the second trimester, the uterus expands up to 20 times its normal size, breasts enlarge, and fetal movements may be felt.
- The fetus grows the fastest and gains the most weight during the third trimester. The abdomen drops, and the fetal movement becomes quite strong. The woman is prepared to give birth.
Thus, we can conclude that to accommodate the growing fetus, several anatomical changes must occur in the female body, including placental development, weight gain, abdominal extension, breast enlargement, glandular development, and posture changes.
