Magnesium is a vital electrolyte that plays a crucial role in many biochemical reactions in the human body, affecting cellular function, nerve conduction, and other needs. Normal serum magnesium levels are between 1.46 and 2.68 mg/dL. Hypomagnesemia is an electrolyte disturbance caused by a low serum magnesium level of less than 1.46 mg/dL in the blood. However, this condition is typically asymptomatic until serum magnesium concentration is less than 1.2 mg/dL (0.5 mmol/L).
Chronic disease, alcohol use disorder, gastrointestinal loss, renal loss, and other conditions can be attributed to hypomagnesemia. Signs and symptoms of hypomagnesemia include mild tremors and generalized weakness to cardiac ischemia and death.
