Occasionally, a twin or triplet pregnancy occurs by chance. In other instances, particular factors are at work. For instance, twin pregnancies become more common as you age, since hormonal changes might result in the production of more than one egg at a time. Twins or other multiples are also more likely to occur when assisted reproductive methods such as in vitro fertilization are used. The most frequent kind of twins is fraternal twins, which develop when two distinct eggs are fertilized by two distinct sperm. Each twin is born with a separate placenta and amniotic sac. Twins might be two females, two males, or a boy and a female.
When a single fertilized egg divides and develops into two babies, identical twins emerge. Twins that are identical may share a placenta and an amniotic sac, or they may share a placenta but have different amniotic sacs. The two infants are genetically similar. They’ll be of the same sex and share physical attributes and traits. Identical twins seldom fail to fully divide into two persons. These infants are referred to as conjoined twins. Triplets and higher-order multiples might be identical, fraternal, or a mix of the two.
Complications of twins Pregnancy.
Preterm labor and birth- Over three out of every five twins and virtually all higher-order multiples are born prematurely (born before 37 weeks). The more fetuses present during pregnancy, the greater the chance of preterm delivery. Premature birth occurs when a baby’s body and organ systems have not completely formed. These infants are often premature and have low birth weights. This equates to a weight of less than 5.5 pounds (2,500 grams). They may need assistance breathing, eating, fighting infection, and maintaining body temperature.
Gestational high blood pressure-Women carrying multiple fetuses are more than twice as likely to develop prenatal hypertension. This health condition often manifests sooner and is more severe than during a single-baby pregnancy. Additionally, it may increase the likelihood of the placenta detaching prematurely (placental abruption).
Gestational diabetes-Women who have numerous fetuses are at an increased risk of developing gestational diabetes.
Anemia-Anemia is almost twice as prevalent in multiple pregnancies as it is in single births.
Birth defects-Multiple birth kids are almost twice as likely to suffer birth abnormalities (congenital) such as spina bifida and other neural tube disorders, as well as digestive system and heart difficulties.
Miscarriage-In multiple pregnancies, a condition known as the disappearing twin syndrome is more prevalent. It occurs when more than one fetus is discovered but then disappears (or is miscarried). This is a common occurrence throughout the first trimester. This may occur as a result of bleeding. The chance of miscarriage is also increased in the latter trimesters.
Cesarean (C-section) delivery-Unusual fetal postures increase the likelihood of a C-section.
Postpartum hemorrhage – The huge placental region and dilated uterus put a woman at risk for postpartum hemorrhage.
