[Dysgeusias]

J A Tamayo y Orozco, A A Cario

    Revista De Gastroenterologia De Mexico
    |January 1, 1978
    PubMed
    Summary

    Altered taste perception, or dysgeusia, can stem from various conditions, including environmental pollutants and zinc deficiency. Proper diagnosis involves assessing diet, work exposure, and zinc levels, crucial for taste system function.

    Area of Science:

    • Otorhinolaryngology
    • Neuroscience
    • Nutritional Science

    Background:

    • Taste perception involves complex molecular and neural pathways.
    • Dysgeusia, or altered taste, can significantly impact quality of life.
    • Identifying the underlying causes of taste disorders is clinically important.

    Observation:

    • Two cases of dysgeusia are presented: one potentially linked to air pollutants, the other to oropharyngeal aggression.
    • Zinc plays a critical role in taste bud function, gustin synthesis, and neurotransmission.
    • Medications and environmental contaminants can alter zinc levels, affecting taste.

    Findings:

    • Altered taste perception is associated with various pathologic conditions.
    • Zinc is essential for the synthesis of gustin and neurotransmission in the taste system.
    • Clinical evaluation for dysgeusia should include dietary assessment, occupational history, and zinc level determination.

    Implications:

    • Understanding the role of zinc and environmental factors is key to diagnosing and managing taste disorders.
    • Further research into essential trace elements and their impact on sensory systems is warranted.
    • A comprehensive diagnostic approach is necessary for patients experiencing hypogeusia or dysgeusia.
