The complications of low amniotic fluid are as follows: 1. Low amniotic fluid can lead to fetal limb adhesions and increased malformations during pregnancy, and in the middle and late stages of pregnancy, it can lead to chronic intrauterine hypoxia in the fetus, causing intrauterine stillbirth or neonatal asphyxia in severe cases, and neonatal asphyxia may lead to irreversible neurological damage, requiring rehabilitation treatment such as hyperbaric oxygen at a later stage; 2. Low amniotic fluid can lead to a lower delivery rate in pregnant women, and when the cervical condition is immature or combined with placental hypoplasia, it can increase the chance of cesarean delivery and increase the damage.
