Clinical Information

  • A patient has electrolyte imbalances when the level of electrolytes in their body is too high or too low. These electrolytes play a vital role in ensuring that body fluids are balanced, the heart rhythm is regulated, and nerves and muscles are functioning properly.
  • Some key electrolytes that practitioners often measure to check for electrolyte imbalances are sodium, potassium, calcium, chloride, magnesium, phosphate, and bicarbonate. 
  • There are various causes for electrolyte imbalances, including conditions and medications that may impact one’s natural fluid balance. 
  • Diagnosis typically involves a physical examination and tests for a single substance or multiple substances, like a basic metabolic panel. 
  • Treatment includes providing intervention for the cause of the electrolyte imbalance. However, practitioners usually recommend self-care steps for less severe cases, such as ingesting more electrolyte-rich food or being well-hydrated after physical activity. 

Synonyms Include:

  • Electrolyte Disturbance
  • Ionic Imbalance
  • Mineral Imbalance
