Electrolytes are minerals that dissolve in body fluids to form electrically charged ions, enabling a range of physiological processes. The most important electrolytes in humans are sodium, potassium, chloride, bicarbonate, calcium, magnesium, phosphate, and sulfate. They are distributed between extracellular and intracellular compartments, with specific concentrations maintained by cellular transport and organ systems, especially the kidneys and endocrine glands.

They regulate fluid balance and osmolality, enable nerve impulses and muscle contractions, support acid-base homeostasis, and participate in enzyme activity and metabolic reactions. Sodium and chloride primarily govern extracellular fluid volume; potassium and magnesium are vital for cellular function; calcium is essential for muscle contraction and neurotransmitter release; phosphate participates in energy transfer and bone metabolism.

Electrolyte levels are obtained from the diet and fluids and are adjusted by the kidneys, hormones such as aldosterone and antidiuretic hormone, and, when needed, by shifting between body compartments. Abnormal levels can be caused by dehydration, kidney disease, endocrine disorders, medications, or acute illness and may require measurement through a serum electrolyte panel and correction by oral or intravenous replenishment.

Common medical interventions include isotonic saline (sodium chloride) and balanced solutions such as lactated Ringer's, used to restore circulating volume and electrolyte balance. Providers tailor treatment to the specific imbalance and underlying condition, taking into account kidney function, acid-base status, and cardiovascular risk. Ongoing monitoring of electrolytes guides therapy to avoid overcorrection and complications such as edema or arrhythmias.
