"It has been noted that the gestational diabetes, the incidence is a little more in the multiple pregnancy, probably it is because the multiple pregnancy is seen in a little elderly age group and diabetes is also a problem, which is age related. That could be the reason"

"In general the weight gain will be little minimal or sometimes it may be even there may weight loss in the first trimester because of the excess vomiting and the less intake of the food. But subsequently what happens is there will be a good weight gain, roughly about 2 kgs every month or half kg per week This is the standard weight gain for singleton pregnancy. But in multiple pregnancy, weight gain may be a little more than that because of the extra retention of the water in the mother, increased blood volume in the mother and because of the two fetuses where which both babies contribute to the weight of the mother"

"Let’s try to understand how the multiple pregnancy or how the twin pregnancy is formed. We all know that the sperm unites with the egg and forms the zygote and the zygote keeps on multiplying and undergoes series or stages of the development and forms the embryo. So in twin pregnancy what happens is when there is two types of the twin pregnancy, one is the dizygotic twins and one is the monozygotic twin. Zygocity is refers to the number of eggs from which the baby is formed. So as the name itself indicates that if it is a dizygotic twins, there are two separate eggs that are fertilised by two separate sperms and each one developing into a separate embryo. So that is called as the dizygotic twins and which is common like they are more or less siblings and they may not be of the same sex and there will be having different blood groups and they will be having a different architecture of growth pattern and that is called as non identical twins or fraternal twins or the dizygotic twins and this is very common and this type of twins shows a varied pattern and the incidence of dizygotic twins is increasing because of the increase in pregnancy is happening because of the IVF treatment and also these type of twins show variation in terms of the maternal age and also the parity and also the geographic distribution and also the ethnicity . So these dizygotic twins are more common in women who are of the higher age group and in those women whom we call it as multiparous, those who have had many children and who have had a family history of twins, especially on the maternal side"

"Fetal growth restriction could be seen in multiple pregnancy because of pre-eclampsia problem there is a placental problem, there is a placental pathology and growth restriction is also more common in monochorioinic twins because of the vascular communication between the placenta and sharing of the blood supply by the two babies"

"Monochorioninc and diamniotic twin pregnancy may be associated with the complications and which includes something called as TTTS or Twin-to-twin transfusion syndrome, which is because there are vascular communications between the two placenta. So normally there is no gradient between the two. So it is balanced. So let us say, there is a gradient, So the blood flows, more so from one baby to the other baby, so that one baby acts like the donor and the other baby acts like the recipient. So the recipient baby will have lot of blood and because of the extra blood, the recipient baby’s heart is put into more action. So there is a cardiac strain on the recipient baby and such babies can have excess water around the baby what we call it as a polyhydramnios and such babies will be little bigger. They will go into what is called as a non-immune hydrops and whereas the donor baby will have less water around the baby, goes for what is called as oligamnios and hydramnios and such babies will be very smaller and this is one of the noted and also dreadful complication, which will be identified in the early stage of pregnancy"

"In monozygotic twins what happens is when the zygote keeps on dividing, at one particular stage, the single zygote divides completely into two and each one develops into a separate embryo. That is why it is called as a monozygotic twins. Monozygotic twins genetically they are similar and they share the same blood group and they will be of the same sex. In monozygotic twins what happens is the zygote divides completely into two and each one develops into separate baby. So what happens is in monozygotic twins, they will be of the same sex and they will be of the same blood group and they will be of the same genetic composition. Depending on the stage at which this complete division happens. We call it as diamniotic, dichorionic, monozygotic twins or monoamniotic, monochorionic and monozygotic twins and especially if the division is incomplete, bit the babies may be fused at different levels of the body and that is what we call it as conjoined twins"
