Magnesium Deficiency Overview
Learn About Magnesium Deficiency
Magnesium deficiency is a condition in which the amount of magnesium in the blood is lower than normal. The medical name of this condition is hypomagnesemia.
Low blood magnesium; Magnesium - low; Hypomagnesemia
Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones. Magnesium is needed for many functions in the body. This includes the physical and chemical processes in the body that convert or use energy (metabolism).
When the level of magnesium in the body drops below normal, symptoms may develop due to low magnesium.
Common causes of low magnesium include:
- Alcohol use
- Burns that affect a large area of the body
- Chronic diarrhea
- Excessive urination (polyuria), such as in uncontrolled diabetes and during recovery from acute kidney injury
- Hyperaldosteronism (disorder in which the adrenal gland releases too much of the hormone aldosterone into the blood)
- Kidney tubule disorders
- Malabsorption syndromes, such as celiac disease and inflammatory bowel disease
- Malnutrition
- Medicines including amphotericin, antibodies targeting the epidermal growth factor (EGF) receptor, cisplatin, cyclosporine, diuretics, proton pump inhibitors, tacrolimus, and aminoglycoside antibiotics
- Pancreatitis (swelling and inflammation of the pancreas)
- Excessive sweating
Common symptoms include:
- Abnormal eye movements (nystagmus)
- Convulsions
- Fatigue
- Muscle spasms or cramps
- Muscle weakness
- Numbness
Treatment depends on the severity of the low magnesium problem and may include:
- Fluids given through a vein (IV)
- Magnesium by mouth or through a vein
- Medicines to relieve symptoms

- Respiratory arrest
- Death
When your body's magnesium level drops too much, it can be a life-threatening emergency. Call your provider right away if you have symptoms of this condition.
Treating the condition that is causing low magnesium can help.
If you play sports or do other vigorous activity, drink fluids such as sports drinks. They contain electrolytes to keep your magnesium level in a healthy range.
Summary: Regional citrate anticoagulation (RCA) is the recommended method for anticoagulation in continuous renal replacement therapy (CRRT). However, the optimal post-filter ionized calcium (iCa) target level remains unclear. Currently, it is titrated to a post-filter iCa target ranging from 0.25 to 0.35 mmol/L, which is derived from a few underpowered trials. There are potential side effects associated w...
Summary: Studies have shown that type 2 diabetic patients (T2DM) may have low serum magnesium levels leading to poor control and outcome of the disease. Supplementation with Mg might improve overall diabetic control and disease outcome. However, there is yet no consensus on whether the ionized (iMg) or the total Mg (tMg) level should be used as a basis to determine the status of Mg in the blood. Recently i...
