7 Signs and Symptoms of Magnesium Deficiency

Written by ckv6u

Hypomagnesemia, often known as magnesium deficiency, is a frequently disregarded medical condition.

Magnesium insufficiency is thought to affect less than 2% of Americans, although one study indicates that up to 75% of people are not getting the appropriate amount (1Trusted Source).

Deficit may occasionally go undiagnosed because the apparent symptoms frequently don’t show up until your levels are really low.

Magnesium insufficiency has a variety of causes. They range from poor food intake to the body losing magnesium (2Trusted Source).

Diabetes, poor absorption, persistent diarrhea, celiac disease, and hungry bone syndrome are health issues linked to magnesium depletion. Additionally, those who abuse alcohol are at higher risk (3Trusted Source, 4Trusted Source).

1. Muscle Twitches and Cramps

A lack of magnesium can cause muscle cramps, tremors, and twitches. In the extreme situation, a deficit could potentially result in seizures or convulsions (5Trusted Source, 6Trusted Source).

These symptoms, according to scientists, are brought on by an increased calcium influx into nerve cells, which overexcites or hyperstimulates the muscle nerves (7Trusted Source).

One research found that magnesium supplements are ineffective for treating muscular cramps in older persons, despite the fact that supplementation may help people with deficiencies reduce twitches and cramps in their muscles. Additional research is required in other groups (8Trusted Source).

Remember that there are numerous other potential explanations for involuntary muscular twitches. For instance, they might be brought on by stress or too much caffeine.

2. Mental health disorders

Another potential effect of a magnesium deficit is mental health issues.

One of these is apathy, which is characterized by emotional or mental numbing. Deficiency that has worsened may potentially cause delirium and coma (5Trusted Source).

Furthermore, observational research has linked low magnesium levels to a higher risk of depression (9Trusted Source).

Indirect evidence suggests that a lack of magnesium may increase anxiety, but scientists have made this claim (10Trusted Source).

Magnesium supplements may help some patients with anxiety problems, according to one analysis, although the quality of the evidence is low. Before any judgments can be drawn, better studies are required (11Trusted Source).

In summary, it appears that certain persons may experience nerve malfunction and mental health disorders as a result of magnesium deficiency.

3. Osteoporosis

Weak bones and a higher risk of bone fractures are two symptoms of osteoporosis.

Osteoporosis risk is influenced by a variety of variables. These consist of:

age inadequate exercise inadequate vitamin D and K food intake.
It’s interesting to note that osteoporosis is also a risk factor for magnesium insufficiency. Deficiency may directly damage bones, but it also reduces blood levels of calcium, the primary component of bones (12Trusted Source, 13Trusted Source, 14Trusted Source, 15Trusted Source).

Dietary magnesium deficiency reduces bone mass, according to studies in rats. Despite the fact that no such human experiments have been conducted, studies have linked inadequate magnesium intake to reduced bone mineral density (16Trusted Source, 17Trusted Source).

4. Fatigue and muscle weakness

Another sign of magnesium shortage is fatigue, a state of weakness or tiredness on a physical or mental level.

Remember that everyone has weariness occasionally. Usually, it only implies that you need to get some rest. However, extreme or ongoing tiredness could be a sign of a medical issue.

Because fatigue is a generalized symptom, its underlying cause cannot be determined until it is accompanied by additional symptoms.

Muscle weakness, commonly known as myasthenia, is another more obvious symptom of magnesium shortage (18Trusted Source).

According to researchers, the loss of potassium in muscle cells, a disease linked to a magnesium deficit, is what causes the weakness (19Trusted Source, 20Trusted Source).

As a result, a lack of magnesium is one potential reason for weakness or exhaustion.

5. High blood pressure

Studies on animals suggest that a lack of magnesium may lead to high blood pressure, a significant risk factor for heart disease, and may even raise blood pressure (21Trusted Source, 22Trusted Source).

Although there isn’t enough direct evidence in humans, a number of observational studies indicate that low magnesium levels or a poor diet may increase blood pressure (23Trusted Source, 24Trusted Source, 25Trusted Source).

Controlled studies provide the most convincing proof of magnesium’s health advantages.

Magnesium supplements may lower blood pressure, particularly in individuals with high blood pressure, according to several reviews (26Trusted Source, 27Trusted Source, 28Trusted Source).

Simply put, a lack of magnesium may raise blood pressure, which raises the risk of heart disease. However, further research is required before its function can be fully understood.

6. Asthma

People with severe asthma may occasionally have magnesium insufficiency (29Trusted Source).

In addition, those with asthma typically have lower magnesium levels than people without the illness (30Trusted Source, 31Trusted Source).

Calcium may build up in the muscles lining the lungs’ airways as a result of a magnesium deficiency, according to researchers. The airways narrow as a result, making breathing more challenging (7Trusted Source, 32Trusted Source).

Interestingly, persons with severe asthma may occasionally be given a magnesium sulfate inhaler to assist loosen up and widen their airways. Injections are the primary administration technique for people with life-threatening symptoms (33Trusted Source, 34Trusted Source).

However, there is conflicting information about the usefulness of dietary magnesium supplementation in people with asthma (35Trusted

7. Irregular heartbeat

One of the most severe signs of magnesium shortage is heart arrhythmia, or irregular heartbeat (38Trusted Source).

Most of the time, arrhythmia symptoms are minimal. It frequently exhibits zero symptoms. Heart palpitations, which are pauses in the heartbeat, however, may occur in some persons as a result of it.

Other arrhythmia signs and symptoms include:

chest discomfort and shortness of breath fainting
Arrhythmia may, in the most extreme circumstances, raise the risk of heart attack or stroke.

According to scientists, a condition linked to magnesium shortage, an imbalance of potassium levels within and outside of heart muscle cells may be to blame.

Magnesium levels have been found to be lower in some congestive heart failure and arrhythmia patients than in healthy controls.

Injecting magnesium into those patients had a noticeable positive impact on their heart health (41Trusted Source).

Supplemental magnesium may also lessen symptoms in some arrhythmia sufferers (42Trusted Source).
