Magnesium Deficiency; 10 Warning Signs & Symptoms

Alterations in consciousness

As we have mentioned, severe magnesium deficiency can cause seizures and convulsions. It may also cause a series of alterations in the consciousness ranging from numbness to delirium and even coma. These symptoms appear when the deficiency is severe enough to reach the central nervous system and affect the normal function of the brain. In some cases, magnesium deficiency would manifest as mental confusion; in other cases, it would be apathy and lack of an emotional response. However, every symptom should be taken into consideration because there are plenty of brain issues that may give you alterations in consciousness, and most of them can be life-threatening.
