He explained that it can cause premature birth; increase the risk of the baby being large for its gestational age (macrosomia); lead to placental abruption in which the placenta that links the blood supply to the unborn baby starts to come away from the wall of the womb; and cause perinatal death (stillborn baby), among others.
