Hypomagnesemia

Hypomagnesemia is an electrolyte disturbance with low levels of serum magnesium. Normal magnesium levels are between 1.46–2.68 mg/dL (0.6-1.1 mmol/L) with levels less than 1.46 mg/dL (0.6 mmol/L) defining hypomagnesemia. Like with other electrolyte and fluid imbalances (see also: hyponatremia, hypokalemia, hypocalcemia, hypercalcemia),[1] hypomagnesemia can cause neuropsychiatric symptoms.
