Approximately 6 to 8 percent are high-risk pregnancies. It could be because of the mother’s age of being under 17 or 35 and above, her lifestyle or preexisting health condition such as high blood pressure or diabetes. Sometimes, a medical condition such as Iron deficiency anaemia, Gestational diabetes or Preeclampsia develops during pregnancy, or it could be a result of a history of preterm birth. Twins or multiple births also categorizes as high-risk pregnancies. Each pregnancy is unique, and hence it’s risk level, but with the regular prenatal visits, screenings and treatments where needed, the chances of preterm delivery can be significantly reduced. In fact, since Samitivej Hospital opened its Preterm Prevention Clinic, they have been able to reduce preterm birth by 50% (compared to the WHO’s target).
