Gestational hypertension or pregnancy-induced hypertension (PIH) is the development of new hypertension in a pregnant woman after 20 weeks' gestation without the presence of protein in the urine or other signs of pre-eclampsia. Gestational Hypertension is defined as having a blood pressure greater than 140/90 on two separate occasions at least 6 hours apart.
妊娠期高血压或妊高征（PIH）是指孕妇妊娠20周后出现新的高血压，尿液中没有蛋白质或其他先兆子痫迹象。妊娠期高血压定义：血压在间隔至少6小时的两个不同时间均大于140/90mmHg。
No single diagnostic test currently exists to predict the likelihood of developing gestational hypertension. High blood pressure is the major sign in diagnosing gestational hypertension. Some women with gestational hypertension may present asymptomatic, but a number of symptoms are associated with the condition.
