multi-organ failure due to combined effects of environmental exposure (hyperthermia) and dehydration
AI-generated summary
Jessica Jackson, 18, died from multi-organ failure due to combined hyperthermia and dehydration while weight-cutting for an amateur Muay Thai fight. She lost approximately 9 kg in the final week through water-loading, dehydration, sauna use, and intensive exercise while wearing a sweat suit in 30°C heat. She collapsed during training on the morning of her weigh-in and died 72 hours later in ICU. Key clinical lessons: weight-cutting by acute water loss is extremely dangerous and can cause fatal heatstroke and organ failure, particularly in young athletes unaware of the dangers. Warning signs of critical dehydration (inability to sweat, confusion, weakness) went unrecognised. No medical supervision occurred during her preparation. Clinicians should educate young athletes about safe weight management, recognise that aggressive weight-cutting creates life-threatening vulnerability to heat illness, and advocate for regulatory restrictions on acute water-loss methods in combat sports.

Coroner's recommendations
The Honourable Minister for Sport and Recreation should consider amending the Combat Sports Act 1987 (WA) and Combat Sports Regulations 2004 (WA) to empower the Combat Sports Commission to undertake a greater role in regulating trainers and gyms responsible for training combat sports contestants outside of contests, to improve safety in combat sports in Western Australia. Any additional resources required should be funded by the State Government.
The Combat Sports Commission should consider implementing a scheme requiring contestants to provide their weight at the time of registration (at least 7 days before the contest) in addition to the existing system of formal weigh-in on the day prior and the day of the contest. Commission staff can use this information to determine early whether a contest is safe to sanction. This would likely require legislative amendment to the regulations.
