Pregnancy is a high-risk condition. Some of the more common complications of pregnancy include preeclampsia, small for gestational age (SGA), gestational diabetes mellitus (GDM), and preterm birth. Preeclampsia involves hypertension, protein in the urine, and swelling. If a woman with preeclampsia has a seizure then it becomes eclampsia. SGA are babies that are smaller than they are supposed to be based on the length of the pregnancy. GDM is diabetes that appears during pregnancy and usually resolves after birth. Preterm birth is when the baby comes before his or her due date.
