She competed in the 100 m breaststroke and the 4 × 100 m medley relay at the 2012 Summer Olympics.

Nijhuis competed at the 2008 European Aquatics Championships in Eindhoven in her home country. She failed to qualify for the 2008 Summer Olympics when she performed disappointingly in the 100 m breaststroke. In the 50 m breaststroke she ended 6th in the final after she swam a national record in the semifinal. A few weeks after this championships Nijhuis announced that she would make a step back in her career focusing more on her study and put less hours in her swimming career.

Nijhuis broke the national record in the 50 m and 100 m breaststroke (SC) in Aachen at an early season meet. At the Swim Cup Eindhoven 2008 she lowered the national record in the 50 m breaststroke (LC). The week afterwards she took part in the European Short Course Swimming Championships 2008 in Rijeka, Croatia. There she won her first individual medal, bronze, in the 50 m breaststroke and also reached a 6th place in the 100 m breaststroke, in both events she lowered her own national record. In the 4×50 m medley she won a gold medal alongside Ranomi Kromowidjojo, Hinkelien Schreuder and Marleen Veldhuis equalling the world record that was set by Australia.

After she failed to qualify for the 2007 World Aquatics Championships, Nijhuis bettered the national record in the 50 m and 100 m breaststroke at the Long Course and the 100 m breaststroke at the short course. The European Short Course Swimming Championships 2007 were a big disappointment when she didn't reached any final.

Nijhuis then travelled to Budapest, Hungary for the 2006 European Aquatics Championships. There she ended 6th in the 50 m breaststroke and 25th in the 100 m. With the 4 × 100 m medley team she ended 5th alongside Hinkelien Schreuder, Inge Dekker and Marleen Veldhuis. At the European Short Course Swimming Championships 2006 in Helsinki, Finland she finished 4th in the 50 m breaststroke and 11th in the 100 m breaststroke.

In 2005 Nijhuis qualified for the 2005 World Aquatics Championships in Montreal Canada. She ended 13th in the 50 m breaststroke, the only distance she swam. During the European Short Course Swimming Championships 2005 in Triest, Italy she once again broke the world record in the 4×50 m medley, with the same team as the year before. Individually she ended 7th in the 50 m breaststroke.

After she won the bronze medal in the 50 m breaststroke at the European Junior Swimming Championships 2003 in Glasgow, Scotland. Nijhuis took part in the European Short Course Swimming Championships 2003 in Dublin, Ireland where she won a bronze medal in the 4×50 m medley alongside Hinkelien Schreuder, Chantal Groot and Marleen Veldhuis. At the European Junior Swimming Championships 2004 in Lisbon, Portugal she won two gold medals in the 50 m, breaking the national record of Madelon Baans, and 100 m breaststroke. In December at the European Short Course Swimming Championships 2004 in Vienna, Austria she won a gold medal in the 4×50 m medley together with Schreuder, Dekker and Veldhuis breaking the world record.
