Gestatsiooninädalate

Gestatsiooninädalad, often referred to as weeks of gestation, is a standard measurement used in obstetrics to track the progress of a pregnancy. It indicates the number of weeks that have passed since the first day of a woman's last menstrual period. This system is crucial for determining the estimated due date and for monitoring fetal development.

Pregnancy is typically divided into three trimesters, each spanning approximately 13 gestatsiooninädalat. The first trimester, from week 1 to week 13, is characterized by rapid embryonic and fetal development. The second trimester, from week 14 to week 27, sees continued growth and maturation of the fetus. The third trimester, from week 28 until delivery, focuses on final development and preparation for birth.

Calculating gestatsiooninädalad usually begins with the date of the last menstrual period, as ovulation and conception typically occur about two weeks later. However, ultrasound measurements, particularly in the early stages of pregnancy, can provide a more precise gestational age. This dating is vital for healthcare providers to assess fetal growth, schedule necessary prenatal screenings, and manage potential complications. A full-term pregnancy is generally considered to be between 37 and 40 gestatsiooninädalat.
