When a baby dies in uterus at 20 weeks of pregnancy or later it is known as Still birth.
Causes
A greater proportion of still births seem to occur in otherwise healthy babies and most often the cause is unexplained.
Common causes include:
1. Poor or significantly decreased fetal growth.
2. Placental abruption which means placenta begins to separate before the baby is delivered.
3. Birth defects or chromosomal disorders
4. Infections affecting mother, baby or the placenta.
5. Problems with the umbilical cord like prolapse or knot in the cord.
6. Severe lack of nutrition
7. Lack of oxygen or trauma during delivery
8.Medical conditions in mother like diabetes or high blood pressure.
9.Exposure to toxic environmental agents like pesticides or carbon monoxide.
10. A personal or family history of blood clotting conditions like thrombosis.
11. A previous still birth.
12. Use of Alcohol and drugs during pregnancy.
13.Obese mother
