Hypotonic hyponatremia Hypotonic hyponatremia Hypoosmolar hyponatremia is a condition where hyponatremia associated with a low plasma osmolality. The term "hypotonic hyponatremia" is also sometimes used. When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume. Loss of water is accompanied by loss of sodium. Treat underlying cause and give IV isotonic saline. It is important to note that sudden restoration of blood volume to normal will turn off the stimulus for continued ADH secretion. Hence, a prompt water diuresis will occur. This can cause a sudden and
Exercise-associated hyponatremia drink beyond the dictates of thirst can be deadly." Similarly, authors of the Statement of the Third International Exercise-Associated Hyponatremia Consensus Development Conference claim this advice has "facilitated inadvertent overdrinking and pathological dilutional EAH." Critics of the ACSM's view have questioned their motives, pointing out that Gatorade is one of the organizations "platinum sponsors." Treatments are focused on the underlying cause of hyponatremia and include When EAH is treated early, complete recovery is expected. In addition to the above treatments, athletes experiencing EAH encephalopathy may also receive high-flow oxygen and a rapid infusion of 100 ml of 3% NaCl to
