Several conditions and risk factors can lead to<unk>  or non-reassuring<unk>  status, including: *Low amniotic fluid (oligohydramnios) *If there is too little amniotic fluid around the baby in the uterus, the baby can have trouble moving around in the uterus and its growth and temperature can be impacted. Low amniotic fluid can be caused by placental issues, high gestational blood pressure, some medications, as well as problems with the<unk>  kidney or urinary tract. *Meconium in the amniotic fluid *If a fetus has meconium in their lungs when they are born, this prevents the pressure in their lungs from falling, which normally facilitates the transition to independent breathing. Since aspiration of meconium can lead to improper oxygenation due to obstruction and carries the potential risk for inflammatory pneumonitis, this is an important diagnosis to make in the setting of newborn respiratory<unk> . *Gestational Hypertension *If hypertension in the mother occurs after the 20th week and meets certain criteria, this is considered preeclampsia/eclampsia. The mechanism of preeclampsia/eclampsia is unknown, but consequences if left untreated can include<unk>  growth restriction or death, as well as pose medical risks to the mother. Signs and symptoms of preeclampsia can include swelling, protein in the urine, headaches, vomiting, and abnormal labs that assess kidney and liver function, some of which may be considered severe preeclampsia or eclampsia. * Post-term pregnancy *Breathing problems *Anemia *Abnormal position and presentation of the fetus * Multiple births * Shoulder dystocia * Umbilical cord prolapse * Nuchal cord * Placental abruption * Premature closure of the<unk>  ductus arteriosus * Uterine rupture * Intrahepatic cholestasis of pregnancy, a liver disorder during pregnancy *Maternal diabetes (Type 1 or 2) or gestational diabetes (GDM)
