[|AI|]  Hallow Dear, I do empathize your feelings. Though there are varied causes of such sudden accidental death of the fetus in last trimester of pregnancy, let us consider the commonest cause. One thing is sure that this is a sudden acute episode causing death of the baby. Chronic starvation of baby would have retarded the growth of the baby rather than its death. Diabetes is the commonest cause of sudden intrauterine death of fetus without any other symptoms. Was she tested for blood sugar? If not please get it done with understanding that many times the diabetes shows temporarily during the pregnancy and afterwards becomes latent and non-detectable. The other commoner cause is sudden separation of the placenta. However, usually there is some cause behind it like high blood pressure, diabetes, excessive water around the baby, some bolt on the abdomen, etc. Such separation causes pain in the uterus and may cause some amount of vaginal bleeding - which may not be there also. Please try to explore these possibilities by discussion with your Obstetrician. If you want to discuss this in details with me, you may ask me a Direct question. I hope this gives you some direction.
