Symptoms, complications, factors and diagnosis



It’s always fun to see twins or triplets grow up together. Twin pregnancies are now more common as families often choose infertility treatment. Pregnancies that occur with infertility treatment tend to result in multiple pregnancies.

This blog is a comprehensive guide to multiple pregnancy with a focus on twin pregnancy.

What is a twin pregnancy and how does it happen?

A twin pregnancy is when a mother carries two babies at the same time. Twin pregnancy can happen in two main ways.

  • A fertilized egg can split into two parts and implant in the uterine wall as two different embryos. They are called identical twins. They can look alike and be of the same sex, since the same egg and sperm are involved.
  • Two different sperm can fertilize two eggs at the same time, known as fraternal twins. Fruits may not look the same and may not always be of the same sex, as two different sperm are involved.

What factors increase the likelihood of a twin pregnancy?

Several factors can contribute to a twin pregnancy.

  1. Women over 30 are more likely to conceive multiples. Hormonal changes in adult women prepare their bodies to release more than one egg per month. Thus, the chances of fertilization of all released eggs are high.
  2. Genetics is another important player in ensuring that women carry multiple fetuses. The probability of a twin pregnancy increases dramatically if the mother has twins or if there are twins in the family. This may be due to the transmission of the hyperovulation gene from parent to child.
  3. Research shows that women with a higher BMI and taller height are more likely to have multiple pregnancies, even if the reason is unclear.
  4. Modern infertility treatments have increased the number of twins and multiple pregnancies. In procedures such as IVF, a health care provider may place several fertilized eggs into the mother’s system to increase the chances of a successful pregnancy. All zygotes can develop as babies, resulting in a multiple pregnancy.

How to determine a twin pregnancy?

Only an Ultrasound examination can determine and confirm the number of children in the mother’s womb. The scan helps the healthcare provider check the number of fetuses growing in the uterus. Health professionals may also suspect a multiple pregnancy if more than one heartbeat is heard during a fetal Doppler.

What are the symptoms of multiple pregnancy?

Symptoms during a twin pregnancy can also be slightly different from a singleton pregnancy. The mother may experience more of the following:

  • Morning sickness
  • Heavy vomiting and nausea
  • Rapid weight gain
  • Tender and painful breasts in the first trimester

What are the possible complications of a twin pregnancy?

  • Complications are characteristic of all pregnancies, regardless of the number of children in the mother’s womb. But multiple pregnancies are considered more difficult, and health professionals take extra precautions with such pregnancies.
  • Pregnant women are developing diabetes mellitus due to increased hormones from the placenta. As the placenta increases in multiple pregnancies, the risk of gestational diabetes may also increase. This can affect the baby’s health, and a nutritionist can help the mother manage it gestational diabetes .
  • Premature labor and delivery is the most common complication of twin or multiple pregnancy. A health care professional may recommend injections to extend the pregnancy period for the full development of all the baby’s organs. Premature birth can cause vision, breathing, digestive problems and infection in the newborn.
  • Similar to diabetes, pregnant women can also get gestational diabetes arterial hypertension. Complications double when a woman carries more than one fetus.
  • The placenta may detach from the uterine wall in some women before delivery. This emergency situation is more common in women who carry several children.
  • More than half of cases of multiple pregnancies face complications related to the growth of one of the children. This condition is called intrauterine growth retardation. This can lead to premature birth with low birth weight.
  • Identical twins with identical placentas can develop twin-to-twin transfusion syndrome. In this condition, the babies share their blood, resulting in one baby receiving more blood than the other. This can have a dangerous effect on both children.

How to stay healthy during a twin pregnancy?

A twin pregnancy requires more frequent prenatal visits than a singleton pregnancy. Calorie intake should be optimal for the growth and development of all children and mothers. Research shows that ideally, a mother-to-be should consume an additional 300 calories per child. Along with eating, it’s important to do low-impact exercise to stay healthy.

When you are pregnant with twins, it is very important to hydrate yourself and rest to deal with stress and discomfort. Always choose a health care provider who has experience with multiple births to make the process easier. Research also shows that the odds after giving birth depression high in mothers with twins or multiples. It is very important to take proper care of mothers and children. Always consult a health care professional for mother and baby needs and any medical emergencies.


All pregnancies require attention and care. But multiple pregnancy requires additional care. With proper care and medical care, having many children becomes easier. Physicians must closely monitor complications of preterm birth and fetal growth retardation. Get personalized advice from the right doctor for a smooth pregnancy.

Frequently Asked Questions (FAQ)

What is Vanishing Twin Syndrome?

Missing twin syndrome is the miscarriage of one of the babies during a twin pregnancy. This usually happens in the first trimester, when one of the embryos detected on ultrasound stops developing.

Do twins have the same amniotic sac?

Some twins do share an amniotic sac and placenta. But it is ideal if each baby has its own amniotic sac and placenta for nutritional and protective purposes. Fetal complications such as umbilical cord entanglement and nutrient imbalances can occur when babies live in the same amniotic sac.

Are mothers with multiples more likely to have cesarean births?

yes. The chances of a cesarean section are high in multiple births, as they are more prone to complications.
