Rhabdomyolysis occurs when muscle tissue breaks down and releases harmful substances into the bloodstream. In severe cases, it can lead to kidney damage. The condition can be caused by extreme physical exertion, dehydration, heat stroke, trauma, certain medications, or underlying health issues.

Some questioned whether intense schedules or overexertion played a role, while others directly criticized the agency and demanded better care and proper rest for the group.
Rhabdomyolysis here is likely caused by extreme exertion / exhaustion / exercise which is INSANE! Let them rest!!

Although the exact cause of Yeojun’s condition has not been disclosed, the diagnosis alone has sparked widespread alarm. Fans are now hoping he focuses fully on recovery and returns only when he is completely healthy.
uncore listen up i don’t know what the fuck you are doing but you better get yeojun into the hospital and put him on hiatus NOW. rhabdomyolysis is life threatening and yeojun could have died and will die if he does not get help immediately. pic.twitter.com/lWrEVGUDqw

i desperately hope uncore doesn’t put yeojun back into work once his one week inpatient treatment is over. rhabdo is scary and one week definitely is not enough for proper recovery
and please PLEASE with a second member getting sick due to overworking in a span of four months,…
