Quizplus · Accepted Answer

Hyponatremia is a condition in which the sodium level in the blood is lower than normal. This can occur when fluid losses (such as from vomiting or diarrhea) are replaced with hypotonic fluids (fluids with lower sodium content than the blood). This leads to dilution of sodium in the blood, causing symptoms such as confusion, seizures, and coma.
