Hallow Dear, Placenta is an organ which supplies nutrition, oxygen and hormones to the baby. when placental abruption takes place, baby is deprived of all these; in short, the baby gets suffocated and starved. hence, still birth is a common outcomes of placental abruption. The severity and acuteness depends upon the extent of placental separation. Mostly, the doctor would have started you Sustain to salvage the baby in risk of death; however, when the baby succumbed inspite of the supportive treatment, he had to discontinue the medicine. You should find out the cause behind placental abruption; it could be pregnancy induced hypertension, diabetes, etc. You should treat the cause to prevent recurrence of the accident. You can become pregnant in future. I hope this helps you. Dr. Nishikant Shrotri
