Prematurity happens when a baby is born before 37 weeks’ gestation.
Prematurity happens when a baby is born before 37 weeks’ gestation (time spent developing in the mother's womb). Babies who are part of a multiple birth, such as twins, are more likely to be born prematurely.
Some of the reasons a baby may be born prematurely include:
Abnormally shaped uterus, including heart shaped
Early rupture of the amniotic sac (water breaking)
Cervical incompetence (a cervix that opens before the end of pregnancy)
Chronic medical condition of the mother, such as diabetes or heart disease
