Magnesium deficiency, also known as hypomagnesemia, is an often-overlooked health problem. The symptoms of low magnesium can vary. They can be both physical and mental.
In some cases, deficiency may be underdiagnosed since the obvious signs commonly don’t appear until your levels become severely low.
Health conditions such as diabetes, poor absorption, chronic diarrhea, and celiac disease are associated with magnesium loss. People with alcohol use disorder are also at an increased risk of deficiency.
This article lists 7 symptoms of magnesium deficiency.
Twitches, tremors, and muscle cramps
They may also be a side effect of some medications or a symptom of neuromuscular disease such as muscular dystrophy, multiple sclerosis, or myasthenia gravis.
Common signs of magnesium deficiency include muscle twitches, tremors, and cramps. However, supplements are unlikely to reduce these symptoms in older adults or people who aren’t deficient in magnesium.
Mental health conditions are another possible effect of magnesium deficiency.
Magnesium deficiency may cause lack of emotion, delirium, and even coma. Scientists have suggested that deficiency may also cause anxiety, but no strong evidence supports this idea.
Numerous factors influence the risk of developing osteoporosis, including:
- lack of exercise
- poor dietary intake of vitamins D and K
Magnesium deficiency may be one of the risk factors for osteoporosis and bone fractures, though many factors influence this risk.
Fatigue is a broad term that includes symptoms of physical and mental exhaustion or weakness. Typically, it simply means you need to rest. However, severe or persistent fatigue may indicate a health problem.
Both general fatigue and specific muscle weakness are
Magnesium deficiency may cause fatigue or muscle weakness. However, these are not specific signs of a deficiency unless they are accompanied by other symptoms.
While direct evidence in humans is lacking, research suggests that low magnesium levels or poor dietary intake may raise blood pressure
Evidence suggests magnesium deficiency may raise blood pressure. Additionally, supplements may benefit people with high blood pressure.
However, evidence for the effectiveness of dietary magnesium supplements in individuals with asthma is inconsistent.
Magnesium deficiency has been associated with severe asthma. However, its role in the development of asthma is not entirely understood.
Arrhythmia can range from causing no symptoms to causing very serious symptoms. In some people, it may cause heart palpitations, which are pauses between heartbeats.
In the most severe cases, arrhythmia may increase the risk of stroke or heart failure.
Magnesium deficiency can cause or worsen arrhythmia, or irregular heartbeat, which may increase the risk of more serious complications, such as a stroke or heart failure.

Although many people don’t reach the RDA for magnesium, there are plenty of magnesium-rich foods to choose from.
Magnesium is widely found in both plant- and animal-based foods. The richest sources are seeds and nuts, but whole grains, beans, and leafy green vegetables are also relatively good sources.
If you have a health condition that causes your body to lose magnesium, such as diabetes, it’s important to eat plenty of magnesium-rich foods or take supplements.
Talk with your doctor about creating a plan to increase your magnesium intake that works well for your needs.
The symptoms of magnesium deficiency are usually subtle unless your levels become severely low.
Deficiency may cause:
- muscle cramps
- mental health conditions
- irregular heartbeat
If you believe you may have a magnesium deficiency, you should speak with your doctor.
