Q.
Confusion and Nausea? Why Your Sodium Is Low (Hyponatremia) & Medical Next Steps
A.
Confusion and nausea can be signs of low sodium in the blood, or hyponatremia, which can progress from mild to life-threatening and warrants prompt medical care, especially with severe headache, persistent vomiting, seizures, or extreme drowsiness. There are several factors to consider, from excess water intake and medications to heart, kidney, liver, thyroid, or adrenal problems, and treatment depends on the cause with sodium corrected slowly to avoid harm. See complete details below to learn key risks, when it is an emergency, what tests confirm it, and the right next steps.
