Hyponatremia (American English) or hyponatraemia (British English) is an electrolyte disturbance in which the sodium concentration in the serum is lower than normal. Sodium is the dominant extracellular cation and cannot freely cross the cell membrane. Its homeostasis is vital to the normal physiologic function of cells. Normal serum sodium levels are between 135 and 145 mEq/L. Hyponatremia is defined as a serum level of less than 135 mEq/L and is considered severe when the serum level is below 125 mEq/L.
In the vast majority of cases, hyponatremia occurs as a result of excess body water diluting the serum sodium.
Hyponatremia is most often a complication of other medical illnesses in which excess water accumulates in the body at a higher rate than can be excreted (for example in congestive heart failure, syndrome of inappropriate antidiuretic hormone, SIADH, or polydipsia). Sometimes it may be a result of overhydration.
Lack of sodium is virtually never the cause of hyponatremia, although it can promote hyponatremia indirectly. In particular, sodium loss can lead to a state of volume depletion, with volume depletion serving as signal for the release of ADH (anti-diuretic hormone). As a result of ADH-stimulated water retention, blood sodium becomes diluted and hyponatremia results.
Exercise-associated hyponatremia (EAH), however, is not uncommon. Researchers found, for instance, that 13% of the athletes who finished the 2002 Boston Marathon were in a clinically hyponatremic condition.
Hyponatremia is relatively rare.
Hyponatremia is when the sodium levels in your blood is way too low. This can be caused by an underlying medical condition that basically dilutes the sodium in your body.
Low serum sodium levels (hyponatremia ) are below 130 mM

If you give excessive fluid to human, his kidney will excreate the extra water. But kidney can not excreate the plane water. It is going to wash 'some' salt along with the urine. So this causes hyponatremia.
You might use fluid volume deficit related to hypenatremia
the water content in the body......... because there isn't much water the body needs to conserve some (almost everything in the body needs water) and that is what the adh (anti-diuretic hormone) does
independently associated means TRUELY associated without any confounding factors.
Hyponatremia. Due too fluid overload and diluted levels of sodium in the body. Hyponatremia can lead to serious brain or lung disorders. Just learned about this from our Renal System chapter in my Respiratory Therapy Program.
276.1 is the ICD9 code for hyponatremia. Hyponatremia means low blood sodium levels.
It is called hyponatremia. It is called hyponatremia.
"Sodium deficiency is seen with: (a) excessive sweating. (b) Excessive salt intake. (c) Lack of sodium in the diet. (d) Excessive potassium in the diet.you may know drugs such as diuretics can induced hyponatremia. it means water can take salt out of body or lead to a dilutional hyponatremia.as we can see in the Text Books : Dilutional hyponatremia is associated with congestive heart failure, hyperhidrosis, nephrotic syndrome, cirrhosis, hypoalbuminemia, and acute renal failureso one can expect progressive hyponatremia due to hperhidrosis.
Patients who take diuretic medications must be checked regularly for the development of hyponatremia.
Hyponatremia is spelled as H-Y-P-O-N-A-T-R-E-M-I-A.
This situation is called hyponatremia. See the link below for associated symptoms and diseases.
If you have hyponatremia, start with your primary care provider. The initial testing that your PCP can do will direct you appropriately to the right specialist. There is no one specialist who treats hyponatremia; instead, you have to narrow the possible causes.
Hyperkalemia, hyponatremia have been reported with losartan. This is listed in the adverse effects of losartan by Merck the manufacturers
