Obstetrics. 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. [ 1] Gestational hypertension is defined as having a blood pressure greater than 140/90 on two occasions ...
Cerebral or visual disturbances. Pre-eclampsia is a progressive disorder and these signs of organ dysfunction are indicative of severe pre-eclampsia. A systolic blood pressure ≥160 or diastolic blood pressure ≥110 and/or proteinuria >5g in a 24-hour period is also indicative of severe pre-eclampsia. [ 6]
A classification of hypertensive disorders of pregnancy uses 4 categories as recommended by the U.S. National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy: [10] Chronic hypertension; Preeclampsia-eclampsia; Preeclampsia superimposed on chronic hypertension;
HELLP syndrome. HELLP syndrome is a complication of pregnancy; the acronym stands for hemolysis, elevated liver enzymes, and low platelet count. [ 1] It usually begins during the last three months of pregnancy or shortly after childbirth. [ 1]
Hypertension occurs in approximately 8–10% of pregnancies. [25] Two blood pressure measurements six hours apart of greater than 140/90 mmHg are diagnostic of hypertension in pregnancy. [32] High blood pressure in pregnancy can be classified as pre-existing hypertension, gestational hypertension, or pre-eclampsia. [33]
In the developed world eclampsia rates are about 1 in 2,000 deliveries due to improved medical care whereas in developing countries it can impact 10–30 times as many women. [1] [14] Hypertensive disorders of pregnancy are one of the most common causes of death in pregnancy. [14] They resulted in 46,900 deaths in 2015. [6]
2 per 100,000 per year [ 4] Idiopathic intracranial hypertension ( IIH ), previously known as pseudotumor cerebri and benign intracranial hypertension, is a condition characterized by increased intracranial pressure (pressure around the brain) without a detectable cause. [ 2] The main symptoms are headache, vision problems, ringing in the ears ...
Hypercoagulability in pregnancy is the propensity of pregnant women to develop thrombosis (blood clots). Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding. [1] However, when combined with an additional underlying hypercoagulable ...
