idiopathic
adjectiveid-ee-oh-PATH-ik
meaning in plain English
A health problem that happens for no clear reason, with no one knowing what caused it.
idiopathic: think 'I, doctor, can't spot a cause' — a mystery illness no one can explain.
for example
The doctor said her fatigue was idiopathic, meaning they couldn’t find any reason for it.
Imagine waking up one morning with a strange rash, but your doctor can’t figure out why it’s there—no allergies, no infections, nothing. That’s idiopathic: a problem that just shows up without a known cause. Why does it happen? Sometimes, we just don’t know yet.
