Occam's Razor
A simple cough hides a deadly secret—only the simplest explanation can save a young man's life.
"Occam's Razor" is the third episode of House M.D.'s first season, introducing the diagnostic team's signature method of prioritizing the simplest explanation. The story centers on a young man named Ethan, who presents with a persistent cough and fever. As the team investigates, they uncover a penicillin allergy and ultimately diagnose subacute bacterial endocarditis. While House's characteristic cynicism and unorthodox methods are on display, the episode focuses on the medical puzzle rather than a personal crisis for the doctor.

Lore & Background
The episode highlights the diagnostic team's early dynamic as they learn to navigate House's abrasive style. The medical mystery revolves around a seemingly simple case that defies easy answers, ultimately revealing a hidden allergy and a serious heart infection. Unlike later arcs, House's leg pain and addiction are not central; instead, the focus is on the team's first major collaborative challenge and the application of logical deduction to medicine.
Reader's Guide
The patient presents with seizures and confusion while pregnant, leading the team to suspect eclampsia or rare infections. Initial treatments fail as symptoms worsen, causing House to obsess over complex, unlikely causes like mitochondrial disorders. Red herrings abound as the team tests for everything from heavy metal poisoning to genetic anomalies, but none explain the rapid decline. The breakthrough comes when House realizes the patient's condition mirrors his own hidden struggle with pain and addiction, forcing him to look past the obvious medical data. The final diagnosis reveals a rare autoimmune reaction triggered by the pregnancy itself, which was masked by standard prenatal care. However, the true resolution involves House collapsing from an overdose attempt, exposing his addiction to Cuddy and Wilson, marking a catastrophic low point in his journey.
