Knowledge | Stillbirth: Causes, Symptoms, and Prevention
Definition, Possible Causes, and Management
Stillbirth is the death and delivery of a fetus after 20 weeks of pregnancy. Loss before 20 weeks is called miscarriage. Stillbirth occurs in about 1 in 200 pregnancies and can be devastating, particularly when the pregnancy previously appeared normal.
Most women who experience stillbirth later have a healthy baby. Recurrence is less likely when the cause is a chromosomal abnormality or umbilical cord problem, but risk is higher with chronic maternal disease or inherited parental conditions. Overall, the chance of a subsequent healthy pregnancy is over 90%.
Possible Causes
About half of stillbirths have no identified cause. Known causes include:
Birth defects, with or without chromosomal abnormalities;
Umbilical cord problems such as prolapse, knots, or entanglement that interrupt oxygen supply;
Placental problems such as placental abruption;
Maternal conditions such as diabetes or pregnancy-related hypertension (preeclampsia);
Intrauterine growth restriction (IUGR), which raises the risk of death from inadequate nutrition;
Severe nutritional deficiency or infection;
Environmental toxins such as pesticides or carbon monoxide;
A personal or family history of clotting disorders.
Risk Factors
Risk may be higher with:
A previous stillbirth;
Smoking, heavy alcohol use, or drug misuse;
Obesity;
Maternal age under 15 or over 35.
Symptoms and Management
Stillbirth often has no warning signs, but possible signs include:
Vaginal bleeding, especially abnormal bleeding later in pregnancy, which requires immediate medical attention;
Reduced fetal movement or a change in movement patterns, which requires prompt evaluation.
After a stillbirth, doctors may recommend fetal autopsy and genetic testing to identify the cause and assess future risk. Results may provide answers and emotional reassurance.
If a genetic cause is found, consultation with a genetics specialist may help clarify risks in future pregnancies.
Prevention
Many stillbirths occur without clear risk factors, but risk may be reduced by:
Close monitoring of high-risk pregnancies, including frequent prenatal visits and fetal monitoring for patients with diabetes or hypertension;
Tracking fetal movement, particularly after 26 weeks, and seeking care promptly if movement decreases;
Maintaining a balanced diet, moderate exercise, and taking 400-800 micrograms of folic acid;
Avoiding smoking and alcohol;
Preventing infection by avoiding undercooked food, raw meat, and unpasteurized cheese;
Installing a carbon monoxide detector.
Stillbirth can be psychologically overwhelming. Professional counseling and support groups can help families process grief and rebuild confidence.
