All That You Need To Know About Multiple Pregnancies – Part 2

In Part-1, multiple we got to know a bit about multiple pregnancies. In Part-2 of this article, we will see more about the types and complications associated with multiple pregnancies.

So, what are the types of multiple pregnancies that can occur?

The types of multiple pregnancies are:

  1. Fraternal twins: Two separate eggs get fertilized and are implanted in the uterus, hence they are also referred to as ‘dizygotic’ twins (2 zygotes aka 2 fertilized eggs).The babies may look similar or different and may either be of the same gender (2 boys or 2 girls) or of different genders. This type of multiple pregnancies has the lowest risk amongst all as each baby has its own placenta and amniotic sac.
  2. Identical twins: When a single fertilized egg (embryo) gets split in half and is genetically identical (share the same DNA) the babies formed are identical twins. Hence they are referred to as ‘monozygotic’(1 zygote aka 1 fertilized egg). Such siblings share many characteristics and may or may not look physically similar. Identical twins may have their own placenta and amniotic sac or they may share the same placenta and amniotic sac.
  3. Triplets and ‘higher order multiples’ (HOMs): Three or more pregnancies, i.e., triplets, quadruplets, quintuplets, sextuplets or more. This can be either all identical or all fraternal multiples or a combination of both.

What are the challenges faced during multiple pregnancies?

If you are carrying twins, all we advise you is to be healthy and take adequate care of yourself.
