When the fetus implants in the uterus, the blood vessels are normally calm and functioning properly. In women who experience, pregnancy induced hypertension or preeclampsia, these same vessels constrict causing the blood pressure to rise.

    How Is Pregnancy Induced Hypertension Diagnosed?

    There are three types of pregnancy induced hypertension (PIH). These include:

    Gestational hypertension is the most common form of pregnancy induced hypertension. The pregnant mom will most often be diagnosed with gestational hypertension in the last trimester of the pregnancy and exhibit only an elevated blood pressure reading as a symptom.

    Preeclampsia offers the same symptoms and diagnosis time frame as gestational hypertension. Protein will also be found in the urine during the normal prenatal urine screen.

    Eclampsia is preeclampsia with seizures and is the most serious of all forms of pregnancy induced hypertension. The mother-to-be can suffer from seizures and other complications.
