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.

How does fluid overload in human body cause hyponatremia?
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.
What is a nursing diagnosis for hyponatremia?
A nursing diagnosis for hyponatremia could be "Risk for electrolyte imbalance related to excessive water intake or sodium loss." This reflects the increased vulnerability of the individual to developing further imbalances due to the low sodium levels.
Does hyponatremia result from osmosis or active transport?
Hyponatremia results from an imbalance in the body's water and sodium levels. It can occur due to various reasons such as excessive water intake, certain medications, or certain medical conditions affecting the body's ability to regulate sodium levels. It is not directly caused by osmosis or active transport, but rather by disruptions in the body's normal fluid balance.
What condition might result from an excess of aquaporins?
An excess of aquaporins could lead to increased water reabsorption in the kidneys, potentially causing fluid overload or water retention. This can result in conditions such as hyponatremia (low sodium levels) or fluid buildup in the body tissues (edema).
What sense is associated with the temporal lobe?
The sense associated with the temporal lobe is hearing.
What ICD-9 code is for hyponatremia?
276.1 is the ICD9 code for hyponatremia. Hyponatremia means low blood sodium levels.
What is the scientific term for water intoxication?
It is called hyponatremia. It is called hyponatremia.
Does hyperhidrosis affect 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.
How can hyponatremia be prevented?
Patients who take diuretic medications must be checked regularly for the development of hyponatremia.
How do you spell hyponatremia?
That is the correct spelling of the medical term "hyponatremia" (salt depletion).
Can Prevacid cause hyponatremia?
Yes, Prevacid (lansoprazole), a proton pump inhibitor, has been associated with cases of hyponatremia, although it is not a common side effect. Hyponatremia refers to low sodium levels in the blood, which can occur due to various factors, including medication effects. If someone experiences symptoms of low sodium, such as confusion, seizures, or muscle weakness while taking Prevacid, they should consult a healthcare professional for evaluation and management.
Which medication may be lifesaving for a child who is seizing or comatose from hyponatremia?
In cases of seizures or coma due to hyponatremia, intravenous hypertonic saline (3% sodium chloride) can be a lifesaving treatment. It helps rapidly increase serum sodium levels, mitigating the risks associated with severe hyponatremia. However, it must be administered cautiously to avoid rapid correction, which can lead to osmotic demyelination syndrome. Always consult medical professionals for appropriate dosing and monitoring.
What can not enough salt do to you?
This situation is called hyponatremia. See the link below for associated symptoms and diseases.
Does a gastroenterologist treat hyponatremia?
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.
Does losartan causes hyponatremia?
Hyperkalemia, hyponatremia have been reported with losartan. This is listed in the adverse effects of losartan by Merck the manufacturers
Is nausea a symptom of hyponatremia?
Yes
What is a condition associated with excessive ADH production?
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.
