How does pregnancy-induced hypertension affect the body?

Pregnancy-induced hypertension (PIH) has the capacity to affect both your body and your child's body. Your high blood pressure may inhibit blood flow to some of your vital organs or to your child. This can cause swelling, weight gain, vision problems, and protein in your urine. Occasionally, PIH results in the placenta tearing away from the uterus because of improper nutrition.
