Severe hypomagnesemia usually results in concentrations of
< 1.25 mg/dL (< 0.50 mmol/L)
. Associated hypocalcemia and hypocalciuria are common. Hypokalemia with increased urinary potassium excretion and metabolic alkalosis.
What magnesium level is too high?
Magnesium levels
between 7 and 12 mg/dL
can impact the heart and lungs, and levels in the upper end of this range may cause extreme fatigue and low blood pressure. Levels above 12 mg/dL can lead to muscle paralysis and hyperventilation. When levels are above 15.6 mg/dL, the condition may result in a coma.
What is considered severely low magnesium?
A normal serum (blood) magnesium level is 1.8 to 2.2 milligrams per deciliter (mg/dL). Serum magnesium lower than 1.8 mg/dL is considered low. A magnesium level
below 1.25 mg/dL
is considered very severe hypomagnesemia.
When should hypomagnesemia be corrected?
Treatment of Hypomagnesemia
Treatment with magnesium salts is indicated
when magnesium deficiency is symptomatic or the magnesium concentration is persistently < 1.25 mg/dL (< 0.50 mmol/L)
. Patients with alcohol use disorder are treated empirically. In such patients, deficits approaching 12 to 24 mg/kg are possible.
What is hypomagnesemia level?
Hypomagnesemia is an electrolyte disturbance caused when there is a
low level of serum magnesium (less than 1.46 mg/dL)
in the blood. Hypomagnesemia can be attributed to chronic disease, alcohol use disorder, gastrointestinal losses, renal losses, and other conditions.
What are signs of low magnesium?

lack of
emotion, delirium, and even coma. Scientists have suggested that deficiency may also cause anxiety, but no strong evidence supports this idea.
What is the treatment for hypomagnesemia?
Oral magnesium salts
(eg, magnesium gluconate 500 to 1000 mg orally 3 times a day) are given for 3 to 4 days. Oral treatment is limited by the onset of diarrhea. Parenteral administration is reserved for patients with severe, symptomatic hypomagnesemia who cannot tolerate oral drugs.
What are side effects of low magnesium?
Muscle weakness, confusion, and decreased reflexes
with severely low blood magnesium levels. You may also notice “jerky” movements, high blood pressure, and irregular heart rhythms with severely low blood magnesium levels.
What does low magnesium do to the body?

weaken your bones
, give you bad headaches, make you feel nervous, and even hurt your heart. It can also lead to low levels of other important minerals like calcium and potassium.
