Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used.[2]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.
The causes of hyponatremia are typically classified by a person's body fluid status into low volume, normal volume, or high volume. [4] Low volume hyponatremia can occur from diarrhea, vomiting, diuretics, and sweating. [4] Normal volume hyponatremia is divided into cases with dilute urine and concentrated urine. [4]
The medical word for low sodium levels is hyponatremia. Although it's a fairly common condition, with up to 2% of people having some degree of it, the majority of these patients have only mildly ...
This causes the extracellular fluid (ECF) space to become hypo-osmolar, including a low sodium concentration (hyponatremia). [2] In the intracellular space , cells swell as intracellular volume increases as water moves from an area of low solute concentration (extracellular space) to an area of high solute concentration (the cells' interior).
Traditional treatment for hyponatremia depends on the volume load in the person. For those who are euvolemic (normal body volume load), fluid intake should be restricted. In those that are hypovolemic (low body volume load), give isotonic saline. In those that are hypervolemic (high body volume load), diuresis should be induced. [14]
This is important, as it shows that changes in ECF osmolality have a great effect on ICF osmolality — changes that can cause problems with normal cell functioning and volume. If the ECF were to become too hypotonic, water would readily fill surrounding cells, increasing their volume and potentially lysing them . Many poisons, medications and ...
the physiologic response to a decrease in kidney perfusion is an increase in sodium reabsorption to control hyponatremia, often caused by volume depletion or decrease in effective circulating volume (e.g. low output heart failure). above 2% [citation needed] or 3% [2] acute tubular necrosis or other kidney damage (postrenal disease)
Hyponatremia means that the concentration of sodium in the blood is too low. It is generally defined as a concentration lower than 135 mEq/L. [3] This relatively common electrolyte disorder can indicate the presence of a disease process, but in the hospital setting is more often due to administration of Hypotonic fluids.
