Michelle Trachtenberg died from complications related to diabetes mellitus, according to New York City Office of the Chief Medical Examiner.
The OCME ruled Trachtenberg’s death as natural and the cause was determined after a review of laboratory test results, it confirmed to Rolling Stone. Trachtenberg died suddenly on Feb. 26 at the age of 39.
The news comes after the OCME previously said the cause of Trachtenberg’s death would remain undetermined after the actress’ family declined to have an autopsy performed because of religious reasons. The OCME obliged with the request because no foul play or criminality was suspected in Trachtenberg’s death, hence initially ruling it as “undetermined”; the medical examiner amended it following the laboratory test results. Toxicology testing can be done without an autopsy.
In the years before her death, some of Trachtenberg’s social media posts had sparked concerns among fans about her health. She addressed these in January 2024, writing on Instagram, “I’ve received several comments recently about my appearance. I have never had plastic surgery I am happy and healthy.”
Following her death, reports emerged that Trachtenberg had recently received a liver transplant. One source told People that the actress was “really, really sick and open with those in her circle about how much she was struggling.”
Trachtenberg enjoyed a multifaceted career, first as a child star, then as a recurring favorite in an array of young adult hits. She found early success on the Nickelodeon favorite The Adventures of Pete & Pete before starring in the movie, Harriet the Spy. As a teenager, she joined the cast of Buffy the Vampire Slayer, and later had memorable roles in shows like Gossip Girl and the film, EuroTrip.
