Smell Disorders

Smell disorders group together alterations in the ability to perceive odors, whether by their total or partial loss, by a distorted perception, or by the sensation of smelling something that is not present.

Types that are described: decrease or absence of smell and altered perceptions, such as noticing unpleasant odors without a real source.

Common causes: respiratory infections, persistent nasal congestion, polyps, or other processes that affect the nose; in some cases they are related to general conditions.

Which specialist treats it? The otolaryngologist is the one who evaluates the nose and the pathways of smell; the rheumatologist may intervene when a systemic cause is suspected. If you notice that your sense of smell changed markedly or lastingly, it's advisable to discuss it with a professional to identify the reason.
