Hypothesis
Can rehydration-related hyponatraemia lead to brain herniation in marathon runners?
Conclusion
Hyponatraemia is common in marathon runners, and simple tests like funduscopy could help identify those needing urgent neuroimaging.
Supporting Evidence
- Hyponatraemia occurs in about 13% of marathon runners.
- The patient had a history of severe headaches prior to the marathon.
- Funduscopy may help identify athletes needing neuroimaging.
Takeaway
Sometimes, drinking too much water after running can cause serious brain problems, which can be deadly.
Methodology
Case report detailing the clinical presentation, diagnosis, and management of a marathon runner who died from brain herniation after rehydration.
Limitations
The case is based on a single patient, limiting generalizability.
Participant Demographics
A male in his 30s, Caucasian.
