Massive review seeks to uncover hidden dangers of severe low sodium
NCT ID NCT07576036
First seen Jun 27, 2026 · Last updated Aug 27, 2026 · Updated 2 times
Summary
This study looks back at the medical records of 800 people who were hospitalized with dangerously low sodium levels (≤110 mmol/L). Researchers want to learn how often serious brain complications like swelling or nerve damage occur, and how treatment affects these risks. No new treatments are given—this is purely an information-gathering study to improve future care.
