You can have too many electrolytes, as studies show that excess amounts can have many negative effects on your health. Here are some health implications of having too many electrolytes.

  • Hypernatremia (too much sodium): Hypernatremia can be caused by insufficient fluid intake or excessive water loss. Kidney disease, diabetes, and dementia can also increase the risk of hypernatremia [



  • Hyperkalemia (too much potassium): Hyperkalemia can negatively affect kidney function and cause cardiac arrhythmia, nausea, and irregular heartbeat [





  • Hypercalcemia (too much calcium): Hypercalcemia can lead to fatigue, excessive thirst, nausea, vomiting, heart palpitations, seizures, bone pain, and muscle weakness [



  • Excess magnesium: This can cause stomach upset, nausea, vomiting, diarrhea, and abdominal cramping [


    ]. Though rare, more serious side effects include an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and possibly death [



To help balance electrolytes, be sure to drink enough water throughout the day.
