Magnesium is as an essential metal implicated in numerous physiological functions of human cells. The kidney plays a crucial role in magnesium homeostasis. In advanced chronic kidney disease, serum magnesium levels are increased. Data from experimental and observational studies suggest that low levels of magnesium are associated with several factors, such as insulin resistance, diabetes, oxidative stress, hypertension, atherosclerosis, and inflammation which are implicated in the progression of chronic kidney disease. Moreover, low levels of magnesium have been correlated with cardiovascular disease and all‐cause mortality in end‐stage renal disease patients. Hypomagnesemia has also been associated with poorer renal allograft and transplant recipients' outcomes. The causality of these relationships has not been completely elucidated. A thorough review of the current literature indicates that low magnesium levels in dialysis patients may reflect a poorer nutritional status and/or are the result of systemic inflammation. Further studies in chronic kidney disease and dialysis patients are needed in order to clarify the causality of these associations.
