The most frequent medical condition seen during pregnancy is hypertension. In the United States, hypertensive disorders are one of the leading causes of maternal mortality during pregnancy. A thorough review of the literature on hypertension in pregnancy will be presented. The first section of the article defines and categorizes hypertensive diseases in pregnancy. The physiological changes in the vascular or renal systems that occur during pregnancy are described in depth. We will review the fascinating elements of preeclampsia pathophysiology, with a focus on current developments in the area. The current diagnostic techniques as well as the tests that have been suggested for preeclampsia screening are thoroughly discussed. And also discuss preeclampsia's short- and long-term consequences. Finally, we go through current management recommendations, treatment objectives, and the possible risks and advantages of different antihypertensive medication groups. Preeclampsia is still a mystery, and current care relies on the monitoring and treatment of its symptoms. We hope that this in-depth analysis will spur new research in the area and help practitioners better identify women at risk and treat them.
