Rachel Tussey, a TikTok influencer and mother of three with over 80,000 followers, tragically died following a 'mommy makeover' procedure at the JourneyLite surgery centre in Cincinnati on 25 February 2026. According to a lawsuit filed by her husband, Jeremy Tussey, Rachel suffered a fatal overdose of pain medication in the recovery room. The lawsuit claims that a nurse administered 150 micrograms of fentanyl and 0.5 milligrams of Dilaudid within 30 minutes after surgery, significantly exceeding the amount given during the nine-hour operation. This overdose reportedly led to a loss of oxygen to Rachel’s brain for more than six minutes, during which staff failed to respond urgently. She was eventually transported to Bethesda North Hospital, declared brain dead, and later died in hospice care on 17 March 2026. Rachel’s surgeon, Dr Shahryar Tork, also filed a separate lawsuit accusing the surgery centre of negligence and failure to provide proper care. The lawsuits allege systemic failures, regulatory violations, and even attempts to alter medical records posthumously. Jeremy Tussey is seeking compensation exceeding $25,000 per claim, punitive damages, and legal fees. JourneyLite has denied all allegations. The case highlights serious concerns about post-operative care and opioid administration in cosmetic surgery centres.
