Michelle Trachtenberg previously addressed concern over her well-being, just a year before quietly undergoing a liver transplant ahead of her death at age 39. 

In January 2024, she slammed speculation that she was in poor health after some of her followers expressed worry over her seemingly ‘thinning hair’ and ‘yellow eyes.’

In response to an Instagram comment saying that she looked ‘sick’ and asking if she was okay, the Gossip Girl alum replied: ‘Fun fact. This is my face. Not malnutrition no problems. Why do you have [to] hate? Get a calendar.’

While addressing another similar comment, at the time, she reminded her fans that she was 38 not 14 anymore, before inquiring in what way she looked unwell. 

‘How sad for you to leave such a comment,’ she concluded.
