What is hyponatremia?

Low sodium: In the blood. If it is too low it can cause coma and or seizures and be very dangerous.

Low salt : Hyponatremia is lower than normal levels of salt in your blood.

Low sodium in blood: Having low sodium ( na) levels in blood is called hyponatremia , usually seen in hospital patients caused by prolonged IV fluid administration , certain tumors use of diuretics etc.

Diuretics: Diuretics-water pills- may cause hyponatremia too.

Hyponatremia: For an excellent link an article on hyponatremia go to: http://www.Mayoclinic.Com/health/hyponatremia/ds00974/dsection=causes this will is a good article regarding what hyponatremia is and what causes it to develop.

See below: Hyponatremia or low sodium level has many causes.Low levels may be asymptomatic or accompanied by non specific symptoms like generalized weakness, and changes in mentation and cognitive function and in severe or rapid lowering of sodium cause seizures.

Low sodium concent'n: Hyponatremia describes a low (<120) sodium to plasma volume ratio. This happens rarely due to low sodium intake, but most commonly is a problem in the excretion of free water (high volume). The causes and approach are complex. Simple treatments such as water restriction also have risks. Ask your nephrologist if you need treatment, and if so, how to proceed.

Low sodium levels: Hyponatremia is a term used to refer to low sodium concentrations in the body. Generally this is due to excess amount of water which dilutes the sodium levels. Although there are a number of reasons for this, it is usually treated by restricted water intake. When severe, hyponatremia can cause changes in mentation and even seizure disorders.

Hyponatremia: Is an electrolyte disturbance in which the sodium ion concentration in the serum is lower than normal. Sodium is the dominant extracellular cation (positive ion) and cannot freely cross from the interstitial space through the cell membrane, into the cell.
