Michelle Trachtenberg’s Cause of Death Has Been Determined

The world of entertainment is mourning the unfortunate death of actress Michelle Trachtenberg, who passed away this year at only 39 years of age. The actress will be remembered for her memorable performances in Harriet the Spy, Buffy the Vampire Slayer, and Gossip Girl as a fixture in the industry for decades.

Cause of Death: Complications of Diabetes Mellitus

After weeks of speculation, the New York City Office of Chief Medical Examiner confirmed that Michelle Trachtenberg died from complications of diabetes mellitus and ruled her death as natural. This news was shared on April 16, 2025, and was first reported by Deadline and later confirmed by People. Ms Trachtenberg was found unresponsive in her New York City apartment on February 26, 2025. The cause was de facto indeterminate because her family declined an autopsy for religious reasons.

Recent Health Issues

Sources familiar with the actress revealed that Trachtenberg had a liver transplant late in 2024. She had been candid with friends about her health issues and was described as a reclusive figure who was increasingly unhealthy looking, appearing pale and gaunt while out in public. Even with health concerns, she responded to speculation in early 2024 by posting a selfie to Instagram with the caption:

"Fun fact. This is my face. No malnourishment, no problems. Why do you have to hate? Buy a calendar."

Tributes from Fellow Actors and Friends

After news of her death broke, she received emotional tributes across social media from fans and celebrities. Sarah Michelle Gellar, Trachtenberg’s co-star on Buffy the Vampire Slayer, shared an emotional quote from the series finale:

"Michelle, listen to me. Listen. I love you. I will always love you. The hardest thing in this world is to live in it. I will be brave. I will live."

Rosie O'Donnell, who starred with Trachtenberg in Harriet the Spy, posted an emotional tribute:

"I loved her very much. She was a great talent and a very nice person."
