[5] At the 2017 Youth World Weightlifting Championships held in Bangkok, Thailand, Fischer won the silver medal in the women's +75 kg event.

[7] In 2018, Fischer won the bronze medal in the women's 90 kg event at the Junior World Weightlifting Championships held in Tashkent, Uzbekistan.

Critics within the Austrian Weightlifting Federation (ÖGV) condemned this approach as unethical, highlighting the risks associated with relying on performance-enhancing stimulants at such a young age.

Concerns about the family’s training environment deepened in 2024, when Fischer’s brother, David, tested positive for trenbolone, an anabolic steroid explicitly banned under World Anti-Doping Agency (WADA) regulations.

This incident exacerbated tensions with the Austrian federation, ultimately contributing to a public fallout and David’s decision to compete internationally for Bulgaria.

Despite Sarah Fischer’s achievements in the sport, her early involvement with stimulants and the broader doping allegations within her family continue to raise serious doubts about the legitimacy of her accomplishments and cast a prolonged shadow over her career.
