Compared with single babies, twins are four times more likely to die in pregnancy, seven times more likely to die shortly after birth and six times more likely to have cerebral palsy. Mothers also face serious health risks from multiple pregnancy.
Women who are pregnant with twins and triplets are more likely to experience health problems such as hypertension (high blood pressure), pre-eclampsia and gestational diabetes than mothers of singletons. They are also twice as likely to die during pregnancy or birth.
At least half of all twins are born earlier than singleton babies and weigh less. They are more likely to experience serious health problems. Twins are also up to six times more likely to die during birth or the first year of life than singletons.
