Amar Al Shibli
Tawam Hospital, UAE
Objectives:
• To review the role of Mg+2 in the body.
• Review the Hypomagnesaemia, its causes, symptoms, and
treatment.
• Set simple approach for hypomagnesaemia.
• Review Hypremagnesemia and its consequences
Mg+2 Hemostasis:
•Mg+2 is the 4thmost common cation in the body and the 2nd
most common intracellular cation.
• The kidney is a major regulator of total body Mg+2
homeostasis.
•Most of filteredMg+2 reabsorbed by the thick ascending loop
of Henle.
Hypomagnesemia is defined as a serum magnesium level less
than 1.8 mg/dL (< 0.74 mmol/L)
Symptoms:
•Most patients are asymptomatic until the concentration of 1.2
mg/dL (0.49 mmol/L).
• Early symptoms are nonspecific and include lethargy and
weakness.
• The prominent organ systems associated with Hypo Mg are
the cardiovascular and neuromuscular.
• Muscle weakness.
• Positive Chevostek sign and Trousseau sign tetany, and
generalized seizures.
