Causes include low dietary intake, alcoholism, diarrhea, increased urinary loss, and poor absorption from the intestines. [1] [4] [5] Some medications may also cause low magnesium, including proton pump inhibitors (PPIs) and furosemide. [2] The diagnosis is typically based on finding low blood magnesium levels, also called hypomagnesemia. [6]
Major causes of hypomagnesemia are from gastrointestinal losses such as vomiting and diarrhea. Another major cause is from kidney losses from diuretics, alcohol use, hypercalcemia, and genetic disorders. Low dietary intake can also contribute to magnesium deficiency. [citation needed]
Hypomagnesemia is relatively straightforward to diagnose, as it is characterized by a low serum magnesium level below 1.5 to 1.8 mg/dL [milligrams per deciliter].
It can cause diarrhea, [8] nausea, vomiting, severely lowered blood pressure, confusion, slowed heart rate, respiratory paralysis. [7] In very severe cases, it can cause coma, cardiac arrhythmia, cardiac arrest and death. [7] Magnesium overdose can be counteracted by administering calcium gluconate. [9]
Still, the blood values are approximately equal between the arterial and venous sides for most substances, with the exception of acid–base, blood gases and drugs (used in therapeutic drug monitoring (TDM) assays). [6] Arterial levels for drugs are generally higher than venous levels because of extraction while passing through tissues. [6]
Electrolytes are minerals that carry an electric charge when dissolved in bodily fluids like blood and cells. These ions or charged particles play a crucial role in various physiological processes ...
Experts share the best magnesium supplements to try for muscle cramps, better sleep, anxiety, and more. Plus, exactly how to tell if you’re low in the mineral.
Among the most common effects of this drug is increased blood cholesterol levels. Other changes in blood chemistry such as hypomagnesemia, hypocalcemia, hyperkalemia, and an increase in blood urea nitrogen (BUN) can occur. [2] [34]
