Twillingegraviditet

Twillingegraviditet refers to a pregnancy involving two fetuses. This can occur in two main ways: through identical (monozygotic) twins, where a single fertilized egg splits into two, or fraternal (dizygotic) twins, where two separate eggs are fertilized by two different sperm. Monozygotic twins are genetically identical, while dizygotic twins share about 50% of their genetic material, similar to regular siblings.

The diagnosis of a twillingegraviditet is typically made during an early ultrasound examination, where the presence of two gestational sacs or two fetuses can be identified. Increased levels of human chorionic gonadotropin (hCG) may also be observed, though this is not a definitive diagnostic tool.

Pregnancies with twins are considered higher risk than singleton pregnancies. Potential complications can include an increased risk of preterm birth, low birth weight for one or both babies, preeclampsia in the mother, and gestational diabetes. If the twins share a placenta (monochorionic twins), there is a specific risk of twin-to-twin transfusion syndrome, where blood flow between the fetuses becomes unbalanced. Regular prenatal care with more frequent monitoring is crucial for managing a twillingegraviditet. The delivery method will be determined based on the position of the fetuses, the presence of complications, and the overall health of the mother and babies.
