  At the time of her death, she had been in a romantic relationship with her agent, Jay Cohen, for five years.
  
  In early 2024, Trachtenberg addressed concerns on social media regarding her health after some people commented on her apparent weight loss and signs of jaundice. She reassured her followers that she was "happy and healthy". Trachtenberg underwent a liver transplant in 2024. Trachtenberg was found unresponsive by her mother in her Manhattan apartment on the morning of February 26, 2025, months after her liver transplant. Emergency medical services were called and pronounced her dead at the scene; she was 39 years old. Authorities stated that her death was not being treated as suspicious. A source told People that during the last year of her life, "She was really, really sick and open with those in her circle about how much she was struggling."
  
  Trachtenberg's family, who are Jewish, objected to an autopsy for religious reasons. There was no suspicion of criminality so the medical examiner did not overrule this objection. New York's Office of Chief Medical Examiner ruled that both the cause and manner of death were undetermined. In April, the New York Chief Medical Examiner declared through toxicology reports that Trachtenberg had died from complications of diabetes, which is sometimes a side effect of organ transplantation.
  
  Following her death, numerous celebrities expressed their condolences and paid tribute to Trachtenberg, including her Buffy the Vampire Slayer and Gossip Girl co-stars. Harriet the Spy co-star Rosie O'Donnell said, "I loved her very much. She struggled the last few years. I wish I could have helped."
