Hyponatremia is a disorder that occurs when the level of sodium in the blood falls below 130mM. Sodium is an electrolyte and helps regulate the amount of water that's in and around the cells. The symptoms of Hyponatremiainclude headache, nausea and vomiting, fatigue, restlessness and irritability, muscle weakness, spasms or cramps, seizures, loss of appetite.
Hyponatrmia is treated with IV sodium solution given intravenously which raise the sodium levels in the blood. Another way is by taking medications to manage the signs and symptoms of hyponatremia, such as headache, nausea and seizures.
The prevalence estimate for hyponatremia ranged from 3.2 million to 6.1 million persons in the U.S. on an annual basis.
