Too Much Magnesium In Blood: Causes, Symptoms & How To Lower It?

Magnesium is one of the electrolytes present in the body. Normal levels are vital for the upkeep of the heart and optimal nervous system functioning. The normal adult value for magnesium is 1.5 – 2.5 mEq/L. Magnesium is excreted by the kidneys. Impairment to the kidneys and when they aren’t working adequately leads to rise in magnesium levels.

Approximately half of the magnesium in the body is located in the bones, however, magnesium also takes part in controlling the blood sugar, blood pressure, muscle movement, nerve functioning, working of the immune system and energy metabolism.

Causes Of Too Much Magnesium In The Blood

When there is a rapid amount of cellular destruction, the components of the cells (magnesium and potassium) move out of the cell, in to the blood stream. Those receiving chemotherapy for Leukemia, Lymphoma, or multiple Myeloma are known to be at risk for Tumor Lysis Syndrome, wherein there is cellular destruction.

Kidneys help to get rid of excess magnesium from the blood stream and the magnesium toxicity restricts their capacity to do so. If the kidneys have already been impaired from a pre-existing disease, they fail to excrete the magnesium from the blood as effectively as healthy kidneys.

The decreased capacity to filter magnesium out of the blood increases the risk of developing severe magnesium toxicity.
