This article provides a comprehensive and in-depth exploration of the multifaceted effects of Hypomagnesemia on human health, with a specific focus on its intricate associations with mechanisms regulating blood pressure and metabolic syndrome. Firstly, the fundamental concept of hypomagnesemia is elucidated, followed by a detailed analysis of its prevalence, risk factors, and Magnesium Deficiency Score. Furthermore, this article delves into the intricate relationship between hypomagnesemia and blood pressure regulation, encompassing its impact on endothelial function, vascular calcification, oxidative stress and inflammatory response, sympathetic nervous system activity as well as the renin–angiotensin–aldosterone system (RAAS). Additionally, it explores the correlation between hypomagnesemia and insulin resistance, metabolic syndrome along with other health issues. Notably noteworthy is that this paper also places special emphasis on exploring the potential role of hypomagnesemia in specific diseases such as renal hypertension and preeclampsia while providing novel insights for their prevention and treatment. Finally, this article summarizes the diverse effects of hypomagnesemia on health while anticipating future research directions. Future studies should further investigate the pathogenesis underlying hypomagnesemia while optimizing assessment methods for magnesium deficiency to develop targeted intervention strategies aimed at offering improved treatment options alongside preventive measures for patients.
