In comparison to a single birth, anaemia is more than twice as likely in multiple pregnancies. The chance of congenital (existing at birth) abnormalities, such as cardiac, gastrointestinal, and neural tube problems (such as spina bifida), is around double in babies of multiple births. expecting triplets or twins. A multiple birth is when you are carrying more than one child. Three babies are triplets, and two babies are twins. As more women use fertility treatments and become pregnant at later ages, multiple pregnancies are becoming more prevalent. Your pregnancy may not necessarily be difficult just because you are carrying multiples. Multiple-pregnant women do, however, have an increased risk of problems like high blood pressure and preterm labour. All multiple pregnancies are therefore regarded as high-risk.
