What is hyponatremia?
Hyponatremia is a condition where the sodium (Na) levels in the blood are lower than normal. Sodium, often referred to a salt and associated with table salt (sodium chloride), is an important electrolyte in the body. It is not the only electrolyte, and therefore not the only salt. Low blood sodium is a fairly common abnormality which can easily be corrected but is dangerous in severe cases. Acute hyponatremia may be seen with a range of conditions, but is more common as a consequence of persistent vomiting and diarrhea as part of dehydration It is when hyponatremia arises with chronic conditions and the long term use of certain medication that there is a greater risk of serious complications and even death.
