Fluid and Electrolyte Replacement

Fluid and electrolyte replacement is a therapeutic strategy aimed at restoring the balance of fluids (water) and electrolytes (such as sodium, potassium, chloride, bicarbonate) in the body. This approach is essential for maintaining homeostasis, especially in conditions involving dehydration, fluid loss (e.g., vomiting, diarrhea), or electrolyte imbalances due to disease or medical interventions. Fluid/electrolyte replacement targets physiological systems rather than a discrete molecule/receptor. It restores normal function by correcting deficits using appropriate intravenous/oral solutions guided by clinical/laboratory assessment.

Corrects fluid and electrolyte deficits through osmosis, passive diffusion, active transport, and hormonal regulation (ADH, aldosterone).
