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.
Mortality associated with hyponatremia approximately doubles reaching 15% as sNa falls from 125 to 110 mEq/L, but the calculated regression (based on a restricted cubic spline) was driven by >20,000 cases with sNa 118 to 137 mEq/L compared with only 113 cases with sNa below 118 mEq/L.
