Olympics

Asian Games
Yeo competed in four Asian Games. In the 1994 Games and the 2002 Games, she won bronze medals in the 100 Butterfly and was the only Singapore swimmer to win a medal at both Games. The 2006 Games was her last international competition.
Southeast Asian Games
Yeo swam at eight SEA Games, and currently hold the record of the most gold medals in SEA Games history with 40 gold medals, surpassing fellow Singaporean swimmer Patricia Chan's record of 39 gold medals. In 1991, Yeo made her SEA Games debut in Manila as a 12-year-old. She won several silvers and bronzes. In 1993, with the Games held in Singapore, Yeo won nine gold medals, which included 7 individual and 2 relay races. At the Games, she lost only one race: the 400 IM to compatriot Ooi Yufen May. In 1995, in Chiangmai, Yeo also won the same seven individual races as in 1993, but lost out on the two relays. She was also the only gold medallist in the Singapore swimming squad. In the 1997 SEA Games, Yeo won three gold medals. In the 1999 Games, Yeo won six gold medals, all in Games Records. She was slated for 12 events, but pulled out of the fourth day of competition, due to a right shoulder injury. The only individual race she lost was the 400 Free, where she managed a bronze, finishing behind Pilin Tachakittiranan of Thailand and compatriot Bouvron Mei-Yen Christel. In 2001, Yeo took part in lesser events as compared to previous SEA games. Yeo won three gold medals. In 2003, Yeo won six gold medals, inclusive of two relay golds. This helped the Singapore women's swim team to clinch their first relay success since 1993. In 2005, Yeo participated in her last SEA Games in Manila, the same city where she debuted for SEA Games. Yeo won six golds. In the 100 Butterfly, Yeo also finally finished in under one minute, winning the race in 59.91s.
Yeo originally wanted to call it a day after the 2005 SEA Games. But after a splendid performance, she decided to continue till the 2008 Beijing Olympics. This decision saw her swim at the 2006 Melbourne Commonwealth Games and the 2006 Asian Games. On 30 January 2007, Yeo announced her retirement at a press conference saying she did not have the motivation to go on with another year of training till Beijing, and retired at 28.
Accolades
Yeo was awarded Singapore's Sportsgirl of the Year award in 1994, and the Sportswoman of the Year awards in 1993, 1995 and 1999. She was prevented from winning any more due to a rule that stopped athletes from winning more than three times. This rule has since been lifted.
Autobiography
In 2004, before the 2004 Olympics, Yeo released her autobiography, titled On the Move: My Career, My Life, which chronicled all the milestones in her life and swimming career, and also nuggets she shared about her national teammates.
Post-swimming career
Yeo opened a swim school, called Yeo's Aquatics, along with her elder brother Leonard. She is also actively involved in church work, working as a mentor within the Youth ministry of New Creation Church. In 2009, Yeo became a non-elected Nominated Member of Parliament for a term of two-and-a-half years, the youngest of her batch.
