Pregnancy-induced hypertension is high blood pressure that occurs during pregnancy. Medical professionals also refer to the condition as gestational hypertension. In some cases, hypertension during pregnancy can lead to a more dangerous condition known as preeclampsia. Preeclampsia is a condition that usually starts after the 20th week of pregnancy and is due to increased blood pressure and protein in the urine. Preeclampsia affects the placenta, and it can affect the mother's kidney, liver, and brain. Preeclampsia is a major cause of fetal complications, which include low birth weight, premature birth, and stillbirth.
High blood pressure in pregnancy may not cause signs or symptoms. If protein is present in the mother's urine, then preeclampsia is present. Other symptoms that can be associated with preeclampsia include persistent headaches, blurred vision, sensitivity to light, and abdominal pain.
