Sensory disorder of smell and/or taste

Last edited: 4/15/2026

Overview

Sensory disorders affecting smell and taste can significantly impair quality of life and nutritional intake. These conditions may arise from various etiologies, including nutritional deficiencies.

Diagnosis

  • Assess dietary intake, particularly focusing on vitamin E levels 1.
  • Conduct olfactory and gustatory function tests to quantify deficits 1.
  • Evaluate for other nutritional deficiencies (e.g., zinc, iron) to rule out contributing factors 1.
  • Management

  • Consider supplementation with vitamin E to address deficiencies observed in patients 1.
  • Recommend a balanced diet rich in antioxidants and essential nutrients 1.
  • No specific drug classes or doses for vitamin E supplementation are detailed beyond general nutritional advice 1.
  • Special Populations

  • Pregnancy: No specific data provided in the abstract 1.
  • Pediatrics: No specific data provided in the abstract 1.
  • Elderly: Nutritional deficiencies, including vitamin E, may be more prevalent and require careful monitoring 1.
  • Comorbidities: Nutritional deficiencies may overlap with other conditions; comprehensive nutritional assessment is advised 1.
  • Key Recommendations

  • Evaluate dietary vitamin E intake in patients with taste and smell dysfunctions to identify deficiencies (Evidence: Moderate 1).
  • Consider vitamin E supplementation for patients identified with inadequate intake, given its potential roles in cellular processes (Evidence: Expert opinion 1).
  • Implement a comprehensive nutritional assessment focusing on multiple nutrients to address underlying deficiencies contributing to sensory disorders (Evidence: Moderate 1).
