Who is at risk for PIH?
PIH is more common during a woman's first pregnancy and in women whose mothers or sisters had PIH. The risk of PIH is higher in women carrying multiple babies, in teenage mothers and in women older than 40 years of age. Other women at risk include those who had high blood pressure or kidney disease before they became pregnant. The cause of PIH isn't known.
