A multiple pregnancy has a higher risk than a single pregnancy, so the surrogate will receive a more comprehensive medical check. The surrogate will have to go to the clinic more times to check the correct fetal development and assess the risk of premature birth. The doctor will indicate how to proceed in each case.
In addition, the surrogate should rest properly to prevent uterine contractions and reduce her physical activity as the pregnancy progresses. It is also essential to follow an adequate diet with daily supplements of folic acid and iron.
The surrogate must acquire the appropriate weight for a twin pregnancy, as otherwise there will be a risk that the babies will have low birth weight. This situation could endanger the survival of babies, so it is vitally important that they reach a minimum weight.
