Gestatsiooninädalat

Gestatsiooninädalat, also known as pregnancy week, refers to a unit of time used to measure the duration of a pregnancy. It is calculated from the first day of a woman's last menstrual period. A full-term pregnancy is typically considered to be 40 gestatsiooninädalat long.

Pregnancy is divided into three trimesters, each spanning approximately 13 gestatsiooninädalat. The first trimester (weeks 1-13) is characterized by rapid fetal development and the formation of major organs. The second trimester (weeks 14-27) is a period of significant fetal growth and increased maternal energy levels. The third trimester (weeks 28-40) focuses on further fetal maturation and preparation for birth.

Tracking pregnancy in gestatsiooninädalat allows healthcare providers to monitor fetal growth and development accurately, schedule prenatal appointments and screenings, and estimate the due date. It is a standard system used worldwide in obstetrics and gynecology. The precise calculation of gestatsiooninädalat is crucial for assessing whether a pregnancy is progressing normally and for making informed decisions regarding prenatal care and delivery. Premature birth is defined as birth before 37 completed gestatsiooninädalat, while post-term pregnancy is generally considered after 42 completed gestatsiooninädalat.
