This is a blood pressure disorder of pregnancy that is diagnosed by two blood pressures taken at least four hours apart that are ≥ 140/90. You must be at least 20 weeks’ gestation in order to be diagnosed with this disorder and have no history of hypertension. We will usually not treat this condition with medication unless the blood pressure warrants it or it progresses in certain ways. However, we will monitor your pregnancy more closely and deliver you at 37 weeks’ gestation (term).
