Gestatsiooninädalad

Gestatsiooninädalad, often referred to as weeks of gestation, represent the standard method of measuring the duration of a pregnancy. This measurement begins from the first day of the woman's last menstrual period. A full-term pregnancy is typically considered to be 40 gestatsiooninädalat.

Pregnancy is commonly divided into three trimesters, each lasting approximately 13 weeks. The first trimester encompasses weeks 1 through 13 and is a period of significant development for the embryo and fetus. During this time, major organs and body systems begin to form. The second trimester spans from week 14 to week 27, and it is often characterized by a decrease in morning sickness and a noticeable growth in the fetus. The third trimester, from week 28 until birth, is when the fetus continues to grow rapidly and prepares for life outside the womb.

Calculating gestatsiooninädalad is crucial for prenatal care. It helps healthcare providers estimate due dates, monitor fetal growth and development, and determine the timing of various screenings and tests. For example, certain genetic screenings are offered within specific gestational windows. Premature birth is defined as delivery before 37 completed gestatsiooninädalat, while post-term birth occurs after 42 completed gestatsiooninädalat. This standardized system ensures consistent communication and care throughout the pregnancy journey.
