Reduced Smell
Partial or complete reduction in the ability to detect odours, which may be temporary or persistent depending on the underlying cause.
Quick answer
Reduced smell / hyposmia (ICD-10: R43.1; ICD-11: MB47) describes partial or complete loss of olfactory ability from viral illness, neurological causes, or post-COVID sequelae. Post-COVID olfactory dysfunction and early Parkinson's disease are important considerations.
