Fluid and electrolyte disorders. Magnesium.

Area of Science:

• Biochemistry
• Clinical Chemistry
• Electrolyte Balance

Background:

• Magnesium is the second most abundant intracellular cation.
• Magnesium plays a critical role in numerous cellular functions.
• Despite its importance, magnesium levels are not routinely measured in clinical practice.

Purpose of the Study:

• To highlight the under-appreciation and under-measurement of intracellular magnesium.
• To emphasize the clinical significance of magnesium in relation to other electrolytes.
• To underscore the complexity in interpreting abnormal magnesium results.

Main Methods:

• Review of existing literature on magnesium's role and measurement.
• Analysis of the interrelationship between magnesium, calcium, potassium, and phosphate.
• Discussion of clinical case scenarios involving electrolyte imbalances.

Main Results:

• Magnesium's essential intracellular role is often overlooked in standard diagnostics.
• Abnormal magnesium levels frequently coexist with imbalances in calcium, potassium, and phosphate.
• The interplay between these electrolytes complicates the diagnosis and management of electrolyte disorders.

Conclusions:

• Increased attention to magnesium measurement is warranted in clinical settings.
• A comprehensive understanding of electrolyte interactions is essential for accurate patient assessment.
• Further research into optimal magnesium monitoring strategies is needed.
