Magnesium testing may be a follow-up to chronically low blood calcium and potassium levels. It also may be ordered when you have symptoms possibly due to a magnesium deficiency, such as muscle weakness, twitching, cramping, confusion, cardiac arrhythmias, and seizures.
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.
Hypomagnesemia usually happens due to one of the following:
Too little intake of magnesium into your body. Excessive loss of magnesium through your kidneys (pee) or your gastrointestinal tract (stool). Movement of magnesium from extracellular fluid into less accessible locations (less common).
Your body needs sufficient magnesium for it to function properly. If you're magnesium deficient it could be contributing to your weight gain or preventing you from losing weight.
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.
When magnesium is so low that it causes symptoms, doctors give magnesium intravenously. They may prescribe oral magnesium as a follow-up treatment. Hypomagnesemia treatment should also include addressing the underlying cause.
Hypomagnesemia occurs with both loop diuretics (furosemide, bumetanide, torsemide, and ethacrynic acid) and thiazide diuretics (chlorothiazide, hydrochlorothiazide, indapamide, and metolazone).
The best way to do this is to include magnesium-rich foods in your diet. Although most foods contain some amount of magnesium, your best bet is to eat lots of leafy greens, nuts, and seeds. Eating a diet packed with these foods should raise your magnesium levels quickly.
Generally speaking, you will find that magnesium supplements start to work after one week of using them. After one week of regular magnesium supplementation, individuals may experience benefits such as improved energy levels, reduced muscle cramps, better sleep quality, and reduced anxiety.
Some experts don't think a blood test is the best way to find out your magnesium level. That's because much of the magnesium in your body is stored in your bones and other places, not in the blood.
In the heart, magnesium plays a key role in modulating neuronal excitation, intracardiac conduction, and myocardial contraction by regulating a number of ion transporters, including potassium and calcium channels.
In developed countries, older data estimated that the prevalence of marginal magnesium deficit is 15%–20% of the population. This corroborates more recent data indicating that around 10%–30% of a given population has subclinical magnesium deficiency based on serum magnesium levels <0.80 mmol/L.
One study. View Source of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep fast, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
Prolonged magnesium deficiency can have an adverse impact on a person's long-term health and increase the risk of chronic diseases, including: heart disease. high blood pressure. type 2 diabetes.
While no single nutrient can promise to help with reducing belly fat, magnesium may assist with preventing deficiencies and conditions that hinder weight loss, including inflammation, insulin resistance and poor blood sugar control.
The role of magnesium is complex and its deficiency is implicated in a number of nonspecific neuropsychological changes such as agitation, fear, anxiety, depression, dizziness, poor attention, insomnia, and restlessness. Some of these symptoms characterize the mental illness known as neurosis.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
