S5, E10: House and the team take on the case of a high-profile fitness trainer who collapses while shooting an infomercial. As the team tests her for possible conditions such as exercise-induced asthma, steroid abuse or even a possible vitamin deficiency due to her strict diet, the patient’s condition continues to worsen. Though she touts herself as an all-natural fitness guru, the team soon discovers she has a slimming secret that may be contributing to her deteriorating condition. Meanwhile, Thirteen begins her participation in a clinical drug trial for Huntington’s disease led by Foreman, Kutner sets up and runs an online medical advice clinic under House’s name and Cuddy moves into House’s office while hers is being repaired, much to the dismay of her new officemate.
