GLOSSARY

Electrolyte Imbalance is a broad term for inappropriate electrolyte conditions, requiring the affected ion and disturbance to be identified.

Concentration is substance per volume, distinct from total body content. Water shifts can raise or lower a value without a proportional change in total element amount. Unit conversion also distinguishes mass from particle quantity; ion charge matters for some units. Interpretation after exercise therefore considers sampling time and fluid status rather than relying solely on the printed laboratory number.

Disturbances can arise from losses, inappropriate intake, illness, medicines or shifts of water and ions; a low value is not always dietary deficiency. Nausea, weakness and cramps are nonspecific, while confusion, seizures or impaired consciousness after exercise require urgent assessment. Identify the disturbance before treatment: giving water or salt indiscriminately can worsen some conditions rather than correct them.

For example, interpret a post-race electrolytes result with sampling time, drinking and recent illness; one value alone is not a supplement prescription.

Balance compares entry and exit over a defined period; homeostasis comprises processes regulating concentration and distribution. Neither means equal amounts of every mineral. Kidneys, intestine, bone and hormones contribute differently for each element. Blood values may sometimes be maintained through redistribution or stores, so one normal concentration does not necessarily summarize the entire nutritional situation or longer-term supply.
