What Are the Symptoms of Magnesium Deficiency?

Magnesium deficiency, also known as hypomagnesemia, is often recognized as a health issue that can be overlooked.

While it is estimated that most people who eat a healthy diet experience magnesium deficiency, studies show that 75% of individuals fail to meet the recommended intake levels. Magnesium deficiency can be very difficult to diagnose because it often does not manifest until magnesium levels in the body are significantly low.

The causes of magnesium deficiency can vary. While inadequate and unbalanced nutrition is a significant factor, magnesium loss from the body can also occur due to certain diseases. Health issues associated with magnesium loss include diabetes, poor absorption, chronic diarrhea, celiac disease, and bone syndrome. People who are alcoholics are also at increased risk.

Some important symptoms of magnesium deficiency are listed below.

Muscle Pain and Cramps

Pain, twitching, or muscle cramps are some of the significant symptoms of magnesium deficiency. In the worst-case scenario, deficiency can lead to seizures or convulsions. Scientists report that these symptoms stem from increased calcium influx into nerve cells, which overstimulate or hyperexcite muscle cells.

While magnesium supplements can alleviate muscle twitches and cramps in those who are deficient, it has been reported that magnesium supplements may be less effective as a treatment for muscle cramps in older adults.

It's important to remember that there can be many other causes of involuntary muscle twitching. For example, stress or excessive caffeine consumption can be triggers. Additionally, some medications’ side effects, neuromyotonia, or neurological diseases like motor neuron disease can present similar symptoms.

While occasional twitches are normal, you should consult your doctor if your symptoms persist.

Mental Disorders

Mental disorders can be another potential outcome of magnesium deficiency. These include apathy, characterized by mental numbness or a lack of emotion. Moreover, some studies have proven that low magnesium levels are associated with an increased risk of depression.

Scientists also believe that magnesium deficiency can increase anxiety. Studies have reported that magnesium supplements are effective in individuals with anxiety disorders.

In summary, it is thought that magnesium deficiency may lead to disturbances in nerve functions and mental issues in some individuals.

Osteoporosis

Osteoporosis is a disease characterized by weak bones and an increased risk of bone fractures. The risk of developing osteoporosis is influenced by various factors, including aging, lack of exercise, and deficiencies in vitamins D and K.

Magnesium deficiency is a risk factor for osteoporosis. The deficiency can weaken bones directly, but it can also lower blood levels of calcium, which is the main building block of bones.

Studies in rats have confirmed that dietary magnesium deficiency leads to a decrease in bone mass. Although such experiments have not been conducted in humans, studies have associated low magnesium intake with lower bone mineral density.

Fatigue and Muscle Weakness

Fatigue, characterized by physical or mental exhaustion or lethargy, is another sign of magnesium deficiency.

Everyone can feel tired from time to time. This typically just means you need to rest. However, severe or persistent fatigue can be a sign of a health issue.

Because fatigue is a nonspecific symptom, it is impossible to identify its cause unless other symptoms accompany it.

Another important sign of magnesium deficiency is muscle weakness, also known as myasthenia. Scientists believe that this weakness arises from the loss of potassium in muscle cells, a condition associated with magnesium deficiency.

Therefore, magnesium deficiency is one of the possible causes of fatigue or weakness.

High Blood Pressure

Studies have shown that magnesium deficiency can increase blood pressure and lead to hypertension, a strong risk factor for heart disease. Research suggests that low magnesium levels or insufficient and unbalanced magnesium intake can elevate blood pressure.

Some reviews have concluded that magnesium supplements can reduce blood pressure, especially in adults with high blood pressure.

Simply put, magnesium deficiency can raise blood pressure, which in turn can increase the risk of heart disease.

Asthma

Magnesium deficiency is sometimes seen in patients with severe asthma. Additionally, individuals with asthma tend to have lower magnesium levels compared to healthy individuals.

Scientists suggest that in cases of magnesium deficiency, calcium may accumulate in the muscles lining the airways of the lungs. This narrows the airways and makes breathing difficult.

To help relax and widen the airways, magnesium sulfate inhalers are sometimes given to individuals with severe asthma. For those with life-threatening symptoms, injections are the preferred route.

In summary, scientists believe that asthma may be a symptom of magnesium deficiency in some patients, but more research is needed to understand its role.

Irregular Heartbeat

Among the most serious symptoms of magnesium deficiency is arrhythmia or irregular heartbeat.

In most cases, arrhythmia symptoms are mild, often without any symptoms at all. However, in some individuals, it can cause palpitations, which are pauses between heartbeats.

Other possible symptoms of arrhythmia include dizziness, shortness of breath, chest pain, or fainting. In the most serious cases, arrhythmia can increase the risk of stroke or heart failure.

Researchers believe that when potassium levels inside and outside of heart muscle cells are imbalanced, this may also be related to magnesium levels.

It has been shown that some patients with congestive heart failure and arrhythmia have lower magnesium levels than healthy individuals. Treating these patients with magnesium injections has been observed to significantly improve heart function.

Magnesium supplements may reduce symptoms in some arrhythmia patients.

How to Get Enough Magnesium?

There are many magnesium-rich foods to choose from. They are abundant in plant-based foods and also commonly found in animal-derived products. The richest sources are seeds and nuts, but whole grains, beans, and leafy green vegetables are also relatively rich sources.

Below are some of the best sources along with their magnesium content per 100 grams:

• Almonds: 270 mg
• Pumpkin seeds: 262 mg
• Dark chocolate: 176 mg
• Peanuts: 168 mg
• Popcorn: 151 mg

For example, just a handful (28.4 grams) of almonds provides 18% of the daily recommended intake of magnesium.

Other significant sources include flaxseeds, sunflower seeds, chia seeds, cocoa, coffee, cashews, hazelnuts, and oats. Magnesium is also added to many breakfast cereals and other processed foods.

If you have a health disorder like diabetes that causes magnesium loss from the body, you should ensure you eat plenty of magnesium-rich foods or take supplements.

Symptoms arising from magnesium deficiency are usually mild unless your deficiency level is severely low. Magnesium deficiency can lead to fatigue, muscle cramps, some mental issues, irregular heartbeat, and osteoporosis.

If you suspect you may have a magnesium deficiency, your concerns can be confirmed with a simple blood test. You should consult your doctor to rule out other possible health issues.

Regardless of the outcome, try to regularly consume whole foods that are rich in magnesium, such as nuts, seeds, grains, or beans.

These foods are also high in other healthy nutrients. Adding these foods to your diet can not only reduce your risk of magnesium deficiency but also improve your overall health.

If you have one or more of the complaints mentioned above, you can visit the nearest health institution for a health check-up.
