Overview

Electrolytes are electrically charged solutes necessary to maintain body homeostasis. The main electrolytes include Sodium (Na), Potassium (K), Chloride (Cl), Calcium (Ca), Phosphorus (P), and Magnesium (Mg). These electrolytes are involved in multiple physiologic and neurohormonal reactions necessary to maintain neuromuscular, neuronal, myocardial, and acid-base balance. Their balance are mainly regulated by renal and endocrine systems, any changes in their balance may be life threatening. Electrolytes are in balance to achieve neutral electrical charges. Electrolytes could be classified based on their electrical charge to anions and cations. Anions include bicarbonate, chloride, and phosphorus. Cations are calcium, magnesium, potassium, and sodium. Sodium and chloride are the major extracellular ions that has the greatest impact on serum osmolality (solute concentration in 1 liter of water). Calcium and bicarbonate are the other major extracellular electrolytes. Main intracellular electrolytes are potassium, phosphorus, and magnesium.

Diagnosis

Diagnosis of electrolyte disturbances is suspected by clinical presentation and will be confirmed by laboratory values. Clinical manifestations depend on the severity of disturbances and their chronicity however, the presentation may vary according to underlying condition. The following table summarizes common symptoms and signs of electrolytes disturbances and important ECG findings.

Disturbance	Chronicity/ Level (meq/L)	Common clinical manifestations		ECG findings
Disturbance	Chronicity/ Level (meq/L)	Symptoms	Signs	ECG findings
Hyponatremia	Early/125-130	Nausea, malaise	Muscle cramps	N/A

 ==Overview==
-Electrolytes are electrically charged solutes necessary to maintain body [[homeostasis]]. The main electrolytes include [[Sodium]] (Na), [[Potassium]] (K), [[Chloride]] (Cl), [[Calcium]] (Ca), [[Phosphorus]] (P), and [[Magnesium]] (Mg). These electrolytes are involved in multiple [[Physiology|physiologic]] and neurohormonal reactions necessary to maintain [[neuromuscular]], [[neuronal]], [[Myocardium|myocardial]], and [[Acid-base homeostasis|acid-base balance]]. Their balance are mainly regulated by [[Kidney|renal]] and [[endocrine]] systems, any changes in their balance may be life threatening. Electrolytes are in balance to achieve neutral electrical charges. Electrolytes could be classified based on their electrical charge to [[anions]] and [[cations]]. Anions include [[bicarbonate]], [[chloride]], and [[phosphorus]]. Cations are [[calcium]], [[magnesium]], [[potassium]], and [[sodium]]. Sodium and chloride are the major extracellular ions that has the greatest impact on serum [[osmolality]] (solute concentration in 1 liter of water). Calcium and bicarbonate are the other major extracellular electrolytes. Main intracellular electrolytes are potassium, phosphorus, and magnesium.
