Patient's question:
NoDoctor's answer:
36 weeks is considered preterm birth, and delivering between 28 and 37 weeks of pregnancy is classified as preterm. Maternal factors include acute infectious diseases, severe anemia, and cardiovascular, liver, kidney, and other internal diseases. Other maternal factors include pregnancy complications, antepartum bleeding, premature rupture of membranes, uterine malformations, and trauma. Fetal factors include twin or multiple pregnancies, polyhydramnios, and fetal malformations. The primary prevention of preterm birth is for pregnant women to undergo regular prenatal examinations to detect these conditions early and actively treat them, thereby eliminating or reducing the factors that may lead to preterm birth.
