Signs & Symptoms Of Low Potassium & Magnesium

Signs & Symptoms of Low Potassium & Magnesium

Mar 29, 2011 | By Jen Weir

The minerals potassium and magnesium are both important electrolytes necessary for proper body function. Potassium works in the maintenance of water balance in your body, as well as in the activation of muscles and nerves. Magnesium is also needed for nerve activity, as well as for the activation of enzymes involved in energy and protein formation. Diarrhea, eating disorders, vomiting, chronic kidney failure, and excessive use of laxatives may cause low potassium. Magnesium deficiency is rare in the United States, but when it does occur, it is generally caused by gastrointestinal disorders that impair absorption or excessive vomiting and diarrhea. There are several signs and symptoms of deficiency in both of these minerals.

Muscular Issues

Muscular issues occur with low levels of potassium and magnesium. Low potassium levels can lead to muscle cramps, while low magnesium levels are associated with muscle spasms. Both minerals are associated with muscular weakness. Paralysis can be a symptom of severe potassium deficiencies.

Irregular Heart Beat

Irregular heartbeat, or arrhythmia, is a known sign and symptom of low levels of potassium and magnesium. Arrhythmia occurs when you suddenly feel and become aware of your heartbeat. It may feel like a flutter, a skipped or extra beat, a rapid or slow heartbeat, or a heartbeat that does not feel normal.

Changes In Mental Function

Low levels of potassium and magnesium can result in changes in mental function. Low potassium can lead to irritability and mental confusion. Low magnesium can be associated with seizures and overall personality changes. According to the Institutes of Health Office of Dietary Supplements, these sudden changes in behavior are likely caused by excessive electrical activity in the brain.
