Fans of tripleS are raising serious concerns over member Kim Chaewon after her recent appearances revealed a drastic and alarming weight loss. Just six months ago, Kim Chaewon was known for her naturally slender yet healthy figure. However, since the beginning of 2026, fans have noticed a significant change in her appearance, with her frame becoming visibly thinner during recent schedules.
According to the idol herself, she is currently undergoing teeth-straightening treatment, which can cause reduced food intake due to pain. While some fans acknowledged this explanation, many believe the extent of her weight loss appears too severe to be attributed solely to dental procedures.


Concern escalated further during the group’s concert “My Secret New Zone,” held in early April. Attendees pointed out that her spine was visibly pronounced even while standing upright, with some describing her physique as “extremely fragile.”


Clips and photos from the concert quickly spread across social media, triggering widespread reactions from both Korean and international fans. Many expressed worry about her health, questioning how she is able to continue performing under such conditions.
Online comments reflected growing unease. Some fans urged the company to step in and prioritize her well-being, even suggesting a temporary hiatus. Others speculated about possible underlying causes beyond dental treatment, though these claims remain unverified.
- “She looks really really sick.”
- “At this point, even if she refuses to eat because of the pain, someone needs to force feed her.”
- “I lost weight when I straightened my teeth too. It hurts so bad. But you gain it back once you get used to the pain and figure out how to eat.”
- “No way it’s because of teeth straightening. There are plenty of ways to get calories and nutrients in by drinking beverages.”
- “Don’t believe her even if she says she’s getting her teeth done. That’s from getting weight loss injections.”
- “A person like that needs to be in the hospital TT.”

Despite differing opinions, the dominant sentiment remains concern for Kim Chaewon’s health. Supporters have called for better care and monitoring, emphasizing that her condition appears to go beyond typical fluctuations in weight. As discussions continue, the situation has reignited broader conversations about idol health, industry standards, and the pressures placed on young performers in K-pop.
