Michelle Trachtenberg Died from Diabetes Complications, Officials Say

• Apr 17, 2025

Michelle Trachtenberg, known for her roles in “Buffy the Vampire Slayer” and “Gossip Girl,” died in February at age 39 due to complications from diabetes mellitus, according to the New York City Office of Chief Medical Examiner.

Her cause of death was officially confirmed on Wednesday. Initially, the cause had been undetermined because Trachtenberg’s family objected to an autopsy. However, after laboratory testing, officials concluded that her death was natural and the result of diabetes-related complications.

The New York Police Department responded to a 911 call on the morning of February 26 at around 8:01 a.m. They arrived at an apartment in midtown Manhattan, where they found Trachtenberg unconscious and unresponsive. At the time, authorities reported that there was no suspicion of criminal activity. In such cases, if foul play were suspected, an autopsy would typically be carried out regardless of family objections.

Diabetes mellitus is a chronic condition that occurs when the body cannot produce enough insulin or effectively use the insulin it does produce. This results in elevated blood sugar levels, which, over time, can lead to serious health complications. These include cardiovascular disease, kidney failure, nerve damage, and even death in severe cases.

Trachtenberg began her acting career at a young age and quickly rose to fame. She landed her breakout role in 1996 at just 11 years old, starring as Harriet in the children’s movie “Harriet the Spy.” She later gained a devoted fan base through her performance as Dawn Summers, Buffy’s younger sister, in the popular TV series “Buffy the Vampire Slayer.” She also played the role of Georgina Sparks in the teen drama “Gossip Girl,” further cementing her place in early 2000s pop culture.

Following her passing, tributes poured in from fans and colleagues. Rosie O’Donnell, who worked with Trachtenberg, called the news of her death “heartbreaking,” reflecting the sorrow felt by many who knew or admired her work.

Michelle Trachtenberg’s death has left a lasting impact on those who grew up watching her and those who worked alongside her throughout her career.
