E J Markley, D A Mattes-Kulig, R I Henkin

    Journal of the American Dietetic Association
    |November 1, 1983
    PubMed
    Summary

    Patients with dysgeusia can be classified by food perception distortions, impacting weight loss. This classification aids in understanding the severity and progression of taste disorders.

    Area of Science:

    • Sensory science
    • Clinical nutrition
    • Gastroenterology

    Background:

    • Dysgeusia, or taste distortion, affects food perception and can lead to significant health consequences.
    • Understanding the classification and progression of dysgeusia is crucial for patient management.

    Purpose of the Study:

    • To classify patients with dysgeusia based on their distorted food and beverage perceptions.
    • To investigate the relationship between dysgeusia classification and weight loss.
    • To characterize common food and beverage distortions in dysgeusia patients.

    Main Methods:

    • Patients were classified into groups based on the number and types of foods/beverages perceived as distorted.
    • Nutritional history was collected using a standard form.
    • A standardized food array of 120 items was developed and used for evaluation.

    Main Results:

    • A classification system for dysgeusia based on food perception was established.
    • A correlation between dysgeusia classification and weight loss was observed, particularly in Types III and IV.
    • Dysgeusia symptoms worsened in 41% of patients, with no reported improvement over time.

    Conclusions:

    • Dysgeusia classification is linked to reduced caloric intake and potential weight loss.
    • The developed standardized food array is useful for evaluating and classifying dysgeusia.
    • Early medical intervention may be associated with faster symptom worsening in some dysgeusia patients.
