Older adults have an increased risk for magnesium deficiency because they tend to consume fewer magnesium-rich foods than younger people. In addition, older adults' bodies may absorb less of the mineral in what they eat, and their kidneys may excrete more of it through their urine.
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.
As noted previously, magnesium deficiency reduces cardiac Na-K-ATPase, leading to higher levels of sodium and calcium and lower levels of magnesium and potassium in the heart. This increases vasoconstriction in the coronary arteries, which can induce coronary artery spasms, myocardial infarction and arrhythmias.
If there is any underlying gut bacteria imbalance or other nutrient deficiencies and these are fixed, magnesium levels should start to improve within 2-4 weeks. However, everyone is different and deficiencies can take a few months for certain individuals.
In the elderly, the importance of an adequate magnesium intake is reiterated as research shows it may preserve cognitive function. Eating a diet rich in magnesium foods can support the daily recommended intake. Another option to consider is food supplements.
Symptoms of Hypomagnesium:
Muscle weakness, confusion, and decreased reflexes with severely low blood magnesium levels. You may also notice "jerky" movements, high blood pressure, and irregular heart rhythms with severely low blood magnesium levels.
A variety of drugs including antibiotics, chemotherapeutic agents, diuretics and proton pump inhibitors can cause magnesium loss and hypomagnesemia (see Table 3).
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).
Magnesium helps maintain a normal heart rhythm and doctors sometimes administer it intravenously (IV) in the hospital to reduce the chance of atrial fibrillation and cardiac arrhythmia (irregular heartbeat). People with congestive heart failure (CHF) are often at risk for developing cardiac arrhythmia.
Aging is very often associated with magnesium (Mg) deficit. Total plasma magnesium concentrations are remarkably constant in healthy subjects throughout life, while total body Mg and Mg in the intracellular compartment tend to decrease with age. Dietary Mg deficiencies are common in the elderly population.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
You can test your magnesium levels by purchasing a simple at-home finger prick test kit which is then analysed at an accredited lab. Forth offers a number of blood tests which include magnesium such as our Nutri-check test and Menopause Health blood test.
While coffee does not directly affect magnesium levels already present in your body, it does, however, affect your body's absorption of magnesium. Some signs of a magnesium deficiency include agitation, anxiety, rapid breathing, muscle tremors or spasms, and irregular heart rhythm.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
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.
If your results show you have a magnesium deficiency, it may be a sign of: Alcoholism. Malnutrition. Preeclampsia (if you are pregnant) Chronic diarrhea.
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.
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.
