Olfactory dysfunction in hemodialysis patients: baseline differences and longitudinal changes compared with healthy controls.

Article C Peer reviewed Observational

Key takeaways

This study tested the sense of smell in 100 people on regular dialysis and 52 healthy people, then tested them again later. The dialysis group scored worse from the start. This shows a link between dialysis and a weaker sense of smell, not proof that dialysis causes it. A dulled sense of smell can make food less appealing, which matters when eating well is already hard.
