Gestatsiooninädal

Gestatsiooninädal refers to a unit of time used to measure the duration of pregnancy. It represents one week of development from conception. Pregnancy is typically divided into weeks, starting from the first day of the last menstrual period, even though conception usually occurs about two weeks later. This system allows for a standardized way to track fetal growth and maternal changes.

The full term of a human pregnancy is approximately 40 gestatsiooninädalat, or 280 days, from the first day of the last menstrual period. However, a pregnancy is considered full-term if it lasts between 37 and 42 weeks. Babies born before 37 weeks are considered premature, and those born after 42 weeks are considered post-term.

Each gestatsiooninädal marks significant milestones in fetal development. For example, by the end of the first gestatsiooninädal, the fertilized egg has traveled to the uterus. By the end of the fourth gestatsiooninädal, the heart begins to beat. As pregnancy progresses, the fetus grows in size, organs develop, and the body prepares for birth. Healthcare providers use gestatsiooninädalat to schedule prenatal appointments, screenings, and to assess the baby's readiness for birth. This standardized measurement is crucial for monitoring the health of both the mother and the developing fetus throughout the pregnancy journey.
