A magnesium deficiency has many different aspects. Muscle cramps, muscle tension, and twitching eyelids are typical signs. Fatigue and nervousness can also be consequences of a magnesium deficiency.
Magnesium deficiency: Symptoms
The signs of magnesium deficiency are diverse. The spectrum extends from neuromuscular symptoms (e.g., nightly leg cramps) and muscle tension right through to twitching of the eyelids. What many are not aware of is that nervousness, fatigue, exhaustion, or sleep disorders, as well as impairments of the cardiovascular system can also occur in association with a magnesium deficiency. Here it is all the more important to ensure a good magnesium supply at an early stage.
Magnesium deficiency: Neuromuscular consequences
Even if too little magnesium is available to the body, the organism will nevertheless attempt to maintain a constant level of magnesium in the blood. For this, magnesium is transferred to the blood from the body’s own reserves (in the muscles, bones, and organs). The resulting deficit expresses itself through different clinical symptoms. First and foremost, these symptoms are neuromuscular. After all, magnesium is essential for vital muscle function and the balance between tension and relaxation in the muscles. This is why muscle and leg cramps are one of the most well-known symptoms of magnesium deficiency.
Additionally, muscle tension and muscle twitching can also occur. Twitching of the eyelids, pins and needles, or even numbness in the fingers and feet are also possible consequences of magnesium deficiency.
Neuromuscular symptoms associated with magnesium deficiency: An overview
- Cramps in the calves
- Muscle cramps, e.g., in the thighs
- Muscle tension
- Twitching of the eyelids
- Muscle twitches
- Pins and needles, numbness in the fingers and feet
Magnesium deficiency: Fatigue, nervousness, and restlessness
Rather unspecific symptoms, such as fatigue, exhaustion, or nervousness, can also occur due to magnesium deficiency because magnesium controls the stimulus conduction in nerve and muscle cells and reduces the release of stress hormones such as adrenaline and cortisol.
Internal restlessness, fatigue, sleep disorders, and tension headaches are further central nervous disorders that can be signs of magnesium deficiency.
Central nervous disorders associated with magnesium deficiency: An overview
- Inner restlessness, nervousness
- Weariness, fatigue
- Tension headaches, migraine
- Sleep disorders
Cardiovascular system impairments associated with magnesium deficiency
Further symptoms of magnesium deficiency that hardly any layperson would associate with insufficient magnesium levels include arrhythmia of the heart and circulation disorders.
Impairment of the cardiovascular system through magnesium deficiency
- Arrhythmia of the heart
- Increasing heart rate
- High blood pressure
- Circulation disorders
If an additional intake of magnesium does not bring about an improvement, a doctor must be consulted to clarify the cause of the complaints, as magnesium deficiency is not always the cause.
