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 at least 6 ...
Up to 50% of gestational hypertension patients go on to develop some form of preeclampsia. [13] Gestational hypertension will normally resolve by 12 weeks postpartum. [13] In this case, the diagnosis of gestational hypertension will be updated to be transient hypertension of pregnancy. [13]
[38] [39] Patients who have gestational hypertension and pre-eclampsia have an increased risk of eclampsia. [41] Furthermore, women with other pre-existing vascular diseases ( diabetes or nephropathy ) or thrombophilia disease such as the antiphospholipid syndrome are at higher risk to develop pre-eclampsia and eclampsia.
Pre-eclampsia is a multi-system disorder specific to pregnancy, characterized by the new onset of high blood pressure and often a significant amount of protein in the urine or by the new onset of high blood pressure along with significant end-organ damage, with or without the proteinuria.
High blood pressure in pregnancy can be classified as pre-existing hypertension, gestational hypertension, or pre-eclampsia. [33] Women who have chronic hypertension before their pregnancy are at increased risk of complications such as premature birth , low birthweight or stillbirth . [ 34 ]
That was followed by preeclampsia (high blood pressure, which, left untreated, can lead to major complications for the mother and/or child), something that is more common among pregnant women in ...
Women do not show signs of hyperaldosterone, such as hypokalemia, hypernatremia, or high blood pressure. The adrenal gland also produces more androgens, such as testosterone, but this is buffered by estrogen's increase in sex-hormone binding globulin (SHBG). [5] SHBG binds avidly to testosterone and to a lesser degree DHEA. [5]
There is a relation with eclampsia and hypertension during pregnancy. [2] [7] [4] [8] The process of PPCM begins with an unknown trigger (possibly a cardiotropic virus or other yet unidentified catalyst) that initiates an inflammatory process in the heart. Consequently, heart muscle cells are damaged; some die or become scar tissue. Scar tissue ...
