Symptoms of magnesium deficiency include nausea and vomiting, fatigue, muscle contractions, and weakness. Extreme or severe magnesium deficiency is a medical emergency and can cause life-threatening heart rhythms, called arrhythmias.
Severe magnesium deficiency can cause problems with the function of your nervous system and heart. It can lead to things like muscle spasms, seizures, or heart arrhythmias. Oral or intravenous magnesium can supplement a low magnesium level. But it's important to find and address the underlying cause.
If the hypomagnesemia is severe, you'll likely be in a hospital and receive fluids and magnesium through an IV. Your provider will also prescribe a treatment plan to manage the underlying cause.
Low magnesium is typically due to decreased absorption of magnesium in the gut or increased excretion of magnesium in the urine. Low magnesium levels in otherwise healthy people are uncommon. This is because magnesium levels are largely controlled by the kidneys.
Magnesium deficiency can cause a wide variety of features including hypocalcaemia, hypokalaemia and cardiac and neurological manifestations. Chronic low magnesium state has been associated with a number of chronic diseases including diabetes, hypertension, coronary heart disease, and osteoporosis.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
Magnesium is also known for its role in the electrical stability and energy balance of cardiomyocytes. Hypomagnesemia has been associated with atrial and ventricular arrhythmias and low serum magnesium could therefore also be a risk factor for sudden cardiac death (SCD).
Signs and symptoms of hypomagnesemia include mild tremors and generalized weakness to cardiac ischemia and death.
Twitches, tremors, and muscle cramps are signs of magnesium deficiency. In worst-case scenarios, deficiency may even cause seizures or convulsions ( 1 , 3 ). Scientists believe these symptoms are caused by a greater flow of calcium into nerve cells, which overexcites or hyperstimulates the muscle nerves (4).
As a result, magnesium deficiency can lead to serious morbidity and mortality, and has been implicated in multiple cardiovascular diseases such as hypertension, cardiomyopathy, cardiac arrhythmia, atherosclerosis, dyslipidaemia and diabetes.
Women should be getting 320 milligrams per day; men, 420 mg. Older people are at risk for magnesium deficiency because they not only tend to consume less of it than younger adults but also may absorb less from what they eat, and their kidneys may excrete more of it.
Hypomagnesemia occurs with both loop diuretics (furosemide, bumetanide, torsemide, and ethacrynic acid) and thiazide diuretics (chlorothiazide, hydrochlorothiazide, indapamide, and metolazone).
If your results show you have a magnesium deficiency, it may be a sign of: Alcoholism. Malnutrition. Preeclampsia (if you are pregnant) Chronic diarrhea.
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
In general rich sources of magnesium are greens, nuts, seeds, dry beans, whole grains, wheat germ, wheat and oat bran. The recommended dietary allowance for magnesium for adult men is 400-420 mg per day. The dietary allowance for adult women is 310-320 mg per day.
Low serum magnesium levels could be associated with increased risk of ischemic stroke, in part, via effects on hypertension and diabetes. Magnesium is a natural calcium antagonist and modulates vasomotor tone, blood pressure, and peripheral blood flow.
Low magnesium levels can also lead to changes in your mood and personality and increase your risk of depression. Some signs might include mental numbness, a lack of feeling emotions, and increased feelings of anxiety, says Shapiro.
Cognitive delays
Commonly referred to as brain fog, slow cognition or difficulty with concentration and memory can all indicate magnesium deficiency. Magnesium is an essential nutrient for the brain, so without it the brain cannot perform as well.
Mg deficiency leads to neurological disorders ranging from apathy to psychosis. Moreover, Mg has an effect on the regulation of synaptic plasticity (4). Several studies have suggested a neuroprotective action of Mg in the synaptic function (5).
Investigations have demonstrated a relationship between the manifestations of stress reactions (anxiety, autonomic dysfunction, and maladjustment) and magnesium deficiency (MD). Thus, mental and physical stresses cause an increase in magnesium elimination from the body.
