What Is Taste and Smell Disorders?
Our senses of taste and smell give us great pleasure. Taste helps us enjoy food and beverages. Smell lets us enjoy the scents and fragrances like roses or coffee. Taste and smell also protect us, letting us know when food has gone bad or when there is a gas leak. They make us want to eat, ensuring we get the nutrition we need. People with taste disorders may taste things that aren't there, may not be able to tell the difference in tastes, or can't taste at all. People with smell disorders may lose their sense of smell, or things may smell different. A smell they once enjoyed may now smell bad to them.

Cross-referenced with NIH MeSH (Taste Disorders, Taste Perception), progression correlates with shifts in Pure-Tone Audiometry & in Taste and Smell Disorders (K05.9: Tympanometry) (Thresholds <= 20 dB HL; normal middle-ear pressure (K05.9)).
Common Symptoms & Clinical Signs
- • Presentation of Taste and Smell Disorders (K05.9): episodic spinning vertigo in Taste and Smell Disorders (K05.9: accompanied by fluctuating)
- • Secondary Taste and Smell Disorders clinical sign: bleeding or receding in Taste and Smell Disorders (K05.9: gums, tooth sensitivity,)
- • Symptom flares in Taste and Smell Disorders correlating with Pure-Tone Audiometry & in Taste and Smell Disorders (K05.9: Tympanometry) deviation outside Thresholds <= 20 dB HL; normal middle-ear pressure (K05.9)
- • Functional ent & hearing impact requiring audiometric/vestibular testing [Taste and Smell Disorders K05.9] evaluation (K05.9)
