The New York City Office of the Chief Medical Examiner confirmed on April 16 that actress Michelle Trachtenberg passed away due to natural causes linked to diabetes mellitus complications. This confirmation comes nearly two months after the 39-year-old was found unresponsive in her Manhattan, New York City apartment on February 26, 2025.
Michelle Trachtenberg, known for her roles in “Buffy the Vampire Slayer,” “Gossip Girl,” and “Harriet the Spy,” was discovered after police responded to a 911 call. Officials reported no evidence of foul play at the location.
According to People magazine, which received the confirmation from the medical examiner, her death was classified as natural. The specific diabetes-related complications leading to her death were not detailed by authorities.
Sources close to Trachtenberg mentioned that she had a liver transplant prior to her passing, though the timing and reason for the surgery remain unspecified. An unnamed source informed NBC News about the transplant, pointing out potential links between diabetes and liver health.
Medical professionals indicate that diabetes can raise the risk of nonalcoholic fatty liver disease, which can lead to severe liver damage or cirrhosis. The conditions share multiple risk factors, creating a complex relationship between them.
The medical examiner’s office respected the family’s religious objections to a full autopsy. Trachtenberg’s family, who are Orthodox Jews, observe customs that typically prohibit disturbing the body after death. Officials determined the cause of death through laboratory tests rather than a complete post-mortem examination.
US Magazine reported that those close to Trachtenberg noticed changes in her health in the year leading up to her death. Sources described her as appearing “pale, gaunt, very thin” and noted she had been “really, really sick” and “struggling” with her health issues.
Despite her health challenges, Trachtenberg had addressed critics commenting on her appearance on social media. She kept her medical conditions private throughout her life.
Trachtenberg began her career as a child actress, appearing in commercials before landing significant roles. Her performance as the titular character in “Harriet the Spy” established her as a promising young talent, and her role as Dawn Summers on “Buffy the Vampire Slayer” broadened her audience.
Her portrayal of Georgina Sparks on “Gossip Girl” demonstrated her range as an actress and is one of her most recognized roles. Trachtenberg also appeared in films such as “EuroTrip” and “Ice Princess,” showcasing her versatility across genres.
Diabetes affects about 38 million Americans and is the eighth leading cause of death in the United States, per ABC News. The condition can lead to numerous complications, including cardiovascular problems, eye disease, nerve damage, kidney disease, and various skin conditions.
For transplant recipients like Trachtenberg, diabetes complications can be particularly challenging. Medical literature indicates that new-onset diabetes can sometimes occur after organ transplantation, potentially related to anti-rejection medications necessary for transplant patients.
At the time of her death, Trachtenberg was active in the entertainment industry and reportedly planned to attend the SXSW Festival shortly before she died. Her sudden passing shocked fans, who were largely unaware of her medical issues.
The news of Trachtenberg’s cause of death emerges as her colleagues and fans continue to honor her memory.
