ER study reveals hidden dangers of treating low sodium
NCT ID NCT06781710
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked back at the records of 1,000 adults who came to the emergency room with very low sodium levels. The goal was to find out how many had brain swelling from the low sodium itself, and how many later developed nerve damage from correcting the sodium too quickly. Researchers hope the findings will help doctors better balance the risks of treatment.
