Systemic Fluid and Electrolyte Balance

Systemic Fluid and Electrolyte Balance refers to the maintenance and regulation of correct proportions and distributions of water and electrolytes (such as sodium, potassium, chloride, calcium, and magnesium) in the body compartments. This systemic state is determined by the integrated action of multiple organs (kidneys, brain, endocrine glands), responsive hormone systems (including the renin-angiotensin-aldosterone system, antidiuretic hormone, and natriuretic peptides), and specialized molecules (such as ion channels and transporters). Imbalances may arise from disease, genetic defects, or drugs affecting these systems, and lead to conditions such as dehydration, edema, and disorders of acid-base homeostasis[1][2][3][4][5][6][7]. Key point: "Systemic Fluid and Electrolyte Balance" is not a single molecular or pharmacological target but rather a complex, integrated physiological process. Drugs and biomarkers relevant to this process target the individual components—not the process as a whole.
