Summary

Magnesium deficiency (hypomagnesemia) is common in hospitalized patients and may not be reflected in serum levels. Early identification of risk factors and proper replacement therapy are crucial for patient health.

Area of Science:

  • Biochemistry
  • Clinical Medicine
  • Human Physiology

Background:

  • Magnesium is the second most abundant intracellular cation and a cofactor in over 300 enzymatic reactions.
  • Hypomagnesemia is prevalent in hospitalized patients, particularly critically ill individuals (approx. 65%).
  • Serum magnesium levels may not accurately indicate intracellular depletion, necessitating alternative assessment methods.

Purpose of the Study:

  • To provide an updated review of common causes of magnesium deficits.
  • To offer practical recommendations for preventing magnesium depletion.
  • To guide correct magnesium replacement therapy and address hypermagnesemia.

Main Methods:

  • Literature review focusing on magnesium's role in health and disease.
  • Analysis of risk factors associated with magnesium deficiency.
  • Discussion of diagnostic challenges and therapeutic strategies.

Main Results:

  • Identified key risk factors for magnesium depletion: diabetes, alcohol abuse, diarrhea, steatorrhea, and diuretic use.
  • Highlighted the inadequacy of serum magnesium levels in reflecting intracellular status.
  • Emphasized the increasing incidence of hypermagnesemia due to kidney failure and expanded use of magnesium salts.

Conclusions:

  • Accurate assessment of intracellular magnesium status is vital, especially when serum levels are misleading.
  • Proactive identification of at-risk patients and timely intervention are essential.
  • Effective management strategies for both magnesium deficiency and excess are necessary in clinical practice.
