The best immediate response if an athlete is suspected of having rhabdomyolysis is:
- Immediately stop all exercise.
- Begin aggressive hydration to protect the kidneys and prevent complications.
- Monitor vital signs and urine output carefully.
- Seek prompt medical evaluation for laboratory testing, including creatine kinase (CK) levels and urinalysis.
- Refer the athlete quickly to a healthcare professional for further diagnosis and treatment.
Early recognition and prompt medical attention are critical to prevent serious complications like acute kidney injury. Rest and hydration are the primary immediate treatments before further management is decided by healthcare providers. The athlete should not return to physical activity until cleared by medical evaluation, typically when CK levels have normalized and symptoms have resolved. This approach is supported by clinical guidelines and expert reviews on exertional rhabdomyolysis management in athletes.
