Omar first represented her country at the 1998 IPC Powerlifting World Championships, held in Dubai. She entered one of the lowest weight categories, the 44 kg, winning the gold medal. Following this success she was selected to compete at the 2000 Summer Paralympics in Sydney, Australia.[2] At the Sydney Games she competed in the 44 kg weight class taking the gold medal with a lift of 109 kg, beating Lucy Ogechukwu Ejike of Nigeria.

After her win in Beijing, Nigeria's Lucy Ejike stated that she would move up to Omar's weight division to challenge for the 56 kg weight class. This led to a showdown at the 2012 Summer Paralympics in London with her rival from Athens.[2][4] Ejike took the lead in the first round with a lift of 135 kg but she was unable to better this attempt, while Omar improved her record from Beijing with a final lift of 142 kg taking her fourth gold medal.[2]
Four years later Ejike and Omar met for the third time at a Paralympic Games, when thy both entered the 2016 Games in Rio.

Ejike improved her lead with her second lift, setting her second world record of the day with a weight of 138 kg.[5] Omar responded with a final lift of 140 kg, putting Ejike into silver medal place.[5] Unfortunately for Omar, Ejike lifted 142 kg to leave Omar with the silver medal for the first time in her Paralympic career.[5]
