  • Title: Hypomagnesemia. A review of pathophysiological, clinical and therapeutical aspects.
    Author: Iannello S, Belfiore F.
    Journal: Panminerva Med; 2001 Sep; 43(3):177-209. PubMed ID: 11579331.
    Abstract:
    The aim of this paper is to discuss, on the basis of an extensive literature review, the role of magnesium (Mg) in health and disease. Mg is an essential cation playing a crucial role in many enzyme systems. Quantitative Mg body stores are regulated by metabolic and hormonal effects on gastrointestinal absorption and renal excretion. Mg is a smooth muscle relaxant, dilates coronary arteries and peripheral vessels, exerts antiarrhythmic effects, may have a permissive effect on catecholamine actions and can play a role in various thrombogenic conditions. Today, hypomagnesemia has become a recognized medical occurrence which may be associated with many different diseases, either genetic or acquired. Mg deficiency is one of the most frequent electrolyte abnormalities in clinical practice, but it is probably the most underdiagnosed one. Clinical manifestations of hypomagnesemia may begin insidiously or dramatically sudden. A large part of the population (especially aged subjects) may have an inadequate Mg intake and a chronic latent Mg deficiency. Routine inclusion of serum Mg analysis in the electrolyte panel represents a continued need to recognize hypomagnesemia and to treat Mg-depleted patients. New clinical studies on Mg deficiency are necessary to ascertain the usefulness and cost-effectiveness of Mg replacement therapy.
