There are numerous causes of fetal demise in the 3rd trimester, in 25-60 % there is no identifiable cause, but there is a study shows about 65 % of deaths are due to placental causes here is a list of the common causes :1- placental : like cord accidents, photo maternal hemorrhage, premature separation of membranes 2- maternal like diabetes, infections, systemic illness, pre-eclampsia or hypertension, thrombophilia 3- fetal like chromosomal or genetic abnormality, infection or fetal HY Chat Doctor. There are few things that you can do to overcome a treatable cause like controlling the blood sugar if diabetic or doing an oral glucose tolerance test in the next pregnancy, high vaginal swab for culture for some types of bacteria, vigorously treating any urinary tract or vaginal infection in the next pregnancy. Searching for inherited thrombophilia can be helpful. I hope this helps
