Will want to evaluate relevant factors in pregnancy and how they can influence pregnancy-induced hypertension among women of child-bearing age (15-44 years).
Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. Hypertensive disorders during pregnancy are classified into 4 categories, as recommended by the National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy :Chronic hypertension, Preeclampsia-eclampsia, Preeclampsia superimposed on chronic hypertension, Gestational hypertension (transient hypertension of pregnancy or chronic hypertension identified in the latter half of pregnancy).
If it were only that simple. For example, "in cases of toxemia or pregnancy-induced hypertension (PIH), the physician should suspect hyperthyroidism in the presence of systolic hypertension with an inappropriate low diastolic blood pressure, a wide pulse pressure, also seen in other conditions such as aortic insufficiency, peripheral A–V fistula and Paget’s disease of the bones."
