Pathophysiology: Hyponatremia means excess of body water compared to total body sodium and potassium. Also likely to involve ADH (vasopressin), the hormone involved in water balance. Total osmolality: concentration of all solutes in a given weight of water (mOsm/kg) regardless of whether or not osmoles move across biological membranes Effective osmolality: number of osmoles that contribute to water movement between intracellular and extracellular compartments Most hyponatremia is from low effective osmolality (hypo-osmotic/hypotonic hyponatremia), but occasionally, hyponatremia occurs in isotonic … Continue reading “hyponatremia”
