In 2001, Hypólito made dramatic improvements. At that year's World Championships, she placed fourth in the all-around, scoring 9.056 on vault, 8.912 on bars, 9.375 on beam and 9.562 on floor. Until Jade Barbosa's bronze medal win at the 2007 World Championships, this placement was the highest AA finish ever achieved by a Brazilian gymnast in Worlds or Olympic competition. Hypólito followed up her strong AA showing by winning Brazil's first ever gymnastics medal, a silver, in the floor exercise event final (9.487). She continued to do well in 2002, winning the all-around and every event final gold except uneven bars at the South American Games and placing 5th on floor at the World Championships (9.237). At the 2003 World Championships Hypólito placed last in the all-around after injuring herself on her first event, however, she helped Brazil qualify a full team for the 2004 Olympics. At the Olympics, Hypólito competed well, helping the Brazilian team to a ninth-place finish and placing 12th in the all-around.
