If one twin dies in the womb in the third trimester then the twin that survives in the third trimester is at an increased risks of complications.
The mother's body will naturally absorb the dead twins tissue and the twin that survived may experience some complications which can include preterm labor, intrauterine growth restriction and in some cases the surviving twin may even die.
When one twin dies in the womb in the third trimester the surviving twin can also be an increased risk of neurological issues or even cerebral palsy, especially if the twins are identical twins.
The deceased twin does not have to be removed as it will be absorbed by the mothers body and can lead to changes in the placental blood flow and amniotic fluid.
If the surviving twin experiences IUGR it means that the surviving twin grows more slowly than expected.
And the surviving twin is often at a higher risk of preterm birth and preterm labor.
The mother may experience preterm labor or even preeclampsia and in rare cases, disseminated intravascular coagulation.
If one twin does die in the womb during the third trimester, doctors will closely monitor the surviving twin and mother and consider whether it's safer for the surviving twin to remain in the womb or be delivered early.
There is also emotional support available if you need it from medical professionals, counselors and support group.
And in some cases the surviving twin may even experience some long term health issues or developmental delays, depending on the severity of the complications during the pregnancy.
