WebIn patients with dilutional hyponatremia the treatment of hyperglycemia is usually followed by a normalization of serum sodium levels [4]. No hypotonic hyponatremia (with a normal measured Posm) can also be due to pseudohyponatremia associated with hyperglycemia– induced severe hypertriglyceridemia and perhaps hypovolemia– induced hyperproteinemia. WebSep 7, 2024 · "In marked hyperglycemia, ECF osmolality rises and exceeds that of ICF, since glucose penetrates cell membranes slowly in the absence of insulin, resulting in movement of water out of cells into the ECF.
