What's the difference between health anxiety and hypochondria?

Short answer
They describe the same phenomenon, but 'hypochondria' was retired because it carried unhelpful moral judgement. The modern term is illness anxiety disorder. The treatment is structured Cognitive Regulation — reducing reassurance-seeking, restricting Googling, and learning to tolerate diagnostic uncertainty. Medication is occasionally adjunctive.
The terminology
'Hypochondria' is the older lay term. Clinicians stopped using it because it became pejorative — implying the person was making it up. The modern term is illness anxiety disorder, and it describes a real condition: persistent preoccupation with having or developing a serious illness, despite reassuring medical evaluations, accompanied by either excessive checking or active avoidance of medical care.
Why it is so resistant to reassurance
Reassurance feels like the fix in the moment, but each round of reassurance teaches the brain that the anxiety was correct to ask, and that the relief depends on the next test or the next opinion. The relief gets shorter and shorter; the cycle compresses. Most patients arrive having had multiple normal scans and consultations, with the anxiety undimmed.
What treatment looks like
A structured CR programme: a Googling fast (often 7–14 days), a reassurance-seeking restriction (no asking spouses or doctors about symptoms outside scheduled review), exposure to the uncertainty (sitting deliberately with 'what if' without resolving it), and the body-first regulation work that reduces the somatic noise the brain has been over-interpreting. Most cases improve significantly within 8–12 weeks.
