What causes fetal distress?

Poor perfusion. Anything that prevents oxygenation of your fetus can cause "distress". Placental abnormalities, premature separation, or cord compression or blockage. Poor blood flow to the uterus can also cause it whether from hemorrhage, ischemia, or injury. Fetal malformations can also cause it. In short, prenatal care ensures that you are not at risk for these and screens for problems with ultrasound & nsts.
Multiple factors. Ombilical cord compressions, abnormalities within the placenta. The main reason for fetal distress in all the cases it s hypoxia caused by different etiologies.
Fetal Distress. There are many causes of fetal distress. One that occurs prior to labor is caused by a placental problem and effects fetal growth. Other causes occur during labor. A common cause during labor is intermittent umbilical cord compression. Sometimes this occurs in a way that a vaginal delivery is possible and sometimes this occurs in a way that an emergency cesarean section is indicated.

Can the sickle cell trait cause fetal distress?

Yes. In a study from the 90's, fetal distress in labour was seen in 17% and 11.5% were delivered by emergency caesarean section. Compared with a comparable group of women without sickle cell trait, the mean birthweight of the babies (3202 g) was not reduced. The main maternal complications were recurrent urinary tract infections (6%) and haematuria (16.5%).

What is fetal distress?

Low fetal health. A decrease in fetal well-being can happen for several reasons. Fetal distress can occur during the pregnancy or during labor. The warning signs are a decrease in the usual daily level of movement, greenish material present in a sample of the amniotic fluid, a decrease in the heart beats on routine check or during a labor contraction.
Archaic term. Fetal distress is not ascertainable prospectively, which is why this term has become obsolete. It has been used to successfully ruin careers of competent obstetricians and should not be used in medical records anymore. One should instead describe the actual findings of fetal surveillance, rather than loosely interpreting them in a cavalier fashion that neglects the complexities of fetal physiology.
