What are the normal serum magnesium levels?

The normal serum magnesium levels are indeed within the range of 1.5 to 2.5 mEq/L. Magnesium is an essential mineral that plays a critical role in numerous bodily functions, including muscle contraction, nerve function, and enzyme activity. Maintaining serum magnesium levels within this range is crucial for ensuring that these essential physiological processes function properly.

Values below 1.5 mEq/L may indicate magnesium deficiency, which can lead to symptoms such as muscle cramping, weakness, and cardiac issues. Conversely, levels above 2.5 mEq/L can suggest hypermagnesemia, which may occur due to renal failure or excessive intake of magnesium supplements, leading to complications such as respiratory failure and cardiac arrest.

Understanding the normal range of serum magnesium is vitally important for healthcare providers in assessing and managing patients' electrolyte balance. This range helps clinicians identify imbalances and associated health issues effectively.
