Specialty: Obstetrics and Gynaecology, neonatology, pediatrics, Symptoms: Fetal death at or after 20 / 28 weeks of pregnancy [1] [2]: Overview tab Causes: Often unknown, pregnancy complications [1] [3] Risk factors
Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange taking place across a membrane in the placenta made of two layers, the syncytiotrophoblast and the cytotrophoblast. Fetal-maternal haemorrhage occurs when this membrane ceases to function as a barrier and ...
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).

Severe pre-eclampsia is a significant risk factor for intrauterine fetal death. A rise in baseline blood pressure (BP) of 30 mmHg systolic or 15 mmHg diastolic, while not meeting the absolute criteria of 140/90, is important to note but is not considered diagnostic.
Among women who know they are pregnant, the miscarriage rate is roughly 10% to 20%, while rates among all fertilisation is around 30% to 50%. [1] [7] In those under the age of 35, the risk is about 10% while in those over the age of 40, the risk is about 45%. [1] Risk begins to increase around the age of 30. [7]
A vanishing twin, also known as twin resorption, is a fetus in a multigestation pregnancy that dies in utero and is then partially or completely reabsorbed. [1] [2] In some instances, the dead twin is compressed into a flattened, parchment-like state known as fetus papyraceus.
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
Women who have high blood pressure or who have had a previous placental abruption and want to conceive must be closely supervised by a doctor. [ 17 ] The risk of placental abruption can be reduced by maintaining a good diet including taking folate , regular sleep patterns and correction of pregnancy-induced hypertension .
