Is it possible to get hyponatremia from dehydration?
4 doctors weighed in across 2 answers
Definitely: Hyponatremia means you have a low sodium level. One way is through dehydration. Dehydration causes hyponatremia usually when a patient is taking a diuretic like hctz (hydrochlorothiazide) or lasix. In this situation, a patient urinates out much more sodium than water. Once this excess sodium is released and the patient's bloodwork is check, there will be much more water than sodium and the pt has hyponatremia.

YES: This is a scenario where the kidney is trying to hold on to water (appropriately) when the sodium amount may be lower than usual. Thus the sodium/plasma volume ratio drops.
