WHAT IT’S REALLY ABOUT
How modern medicine may over-diagnose, over-test, and reshape identity
- O’Sullivan distinguishes over-diagnosis from “wrong diagnosis,” arguing the core issue is whether medicalizing a struggle actually helps the person or simply burdens them with a patient identity.
- Through cases like a teenager labeled with a rare neurogenetic condition and a woman fearing Huntington’s disease, the conversation highlights how belief and attention can amplify symptoms (nocebo/labeling effects).
- They critique a “test-first” culture—scans, biomarkers, and screening—where incidental findings and broadened thresholds (e.g., blood pressure, pre-diabetes) can convert large populations into worried patients.
- The discussion explores controversial areas (autism/ADHD, cancer screening, POTS, long COVID communities) where labels may provide validation and support for some but reduce self-efficacy and expectations for others, especially children.
- Both emphasize “good medicine” as slower, relationship-based care—listening, follow-up, and clinical judgment—alongside a renewed role for generalists to counter harms from hyper-specialization and polypharmacy.
IDEAS WORTH REMEMBERING
5 ideasA diagnosis can be true and still be harmful.
O’Sullivan’s story of diagnosing 15-year-old Abigail with a rare neurodegenerative mutation shows that “finding something” may not help if there’s no treatment and the label changes how a healthy person experiences their body and future.
Labels change physiology indirectly by changing attention and interpretation.
The Huntington’s story (Valentina) illustrates how expecting illness can make ordinary lapses—tripping, airport stress—feel like evidence of decline, escalating anxiety and symptoms until the threatening interpretation is removed.
More testing creates more “abnormalities,” not necessarily more health.
Incidental findings on imaging (back scans, X-rays read as “arthritis”) and screening-detected abnormalities can trigger cascades of follow-up, worry, and treatment even when findings would never have caused harm.
Lowering thresholds medicalizes huge groups for small marginal gains.
They argue that expanding categories like borderline hypertension or pre-diabetes may prevent some events, but at the cost of turning many low-risk people into long-term patients—psychologically, financially (insurance), and medically (side effects).
Screening can save lives and still over-treat many others.
O’Sullivan cites screening trade-offs (e.g., breast cancer: many screened to save one life while more undergo unnecessary treatment) and stresses informed consent plus options like watchful waiting when appropriate.

A diagnosis is not inert. It's not just something that comes with positives or neu- is neutral. It comes with negatives.

Once you learn you have a disease, you can't unlearn it.
— Dr Suzanne O'Sullivan
I think we should be targeting people with multiple risk factors because we know that they're the high risk group, rather than targeting a whole population, including lots of people who have no other risk factors.
