Disorder of taste

Last edited: 4/15/2026

Overview

Dysgeusia refers to an altered or damaged tasting perception, often multifactorial in etiology including polypharmacy, infections, chemotherapy, and radiotherapy. It affects approximately 5% of the population and is linked to significant nutritional status alterations, such as weight loss and poor dietary intake 12.

Diagnosis

  • Clinical history and symptom assessment are crucial 12.
  • No specific diagnostic tests universally recommended; evaluation often includes nutritional status assessment 1.
  • Consideration of comorbid conditions and medication review essential 2.
  • Management

  • Address underlying causes (e.g., medication adjustments, treating infections) 12.
  • Nutritional support and dietary modifications recommended to mitigate weight loss and malnutrition 1.
  • Taste rehabilitation therapies may be considered, though specific drug treatments are not detailed in the abstracts 1.
  • Special Populations

  • Elderly: Higher prevalence and complexity due to polypharmacy and comorbidities; careful management of nutritional intake crucial 2.
  • Comorbidities: Patients with chronic diseases like heart failure and diabetes may require additional dietary counseling to avoid exacerbations 2.
  • Key Recommendations

  • Regularly assess nutritional status in patients with dysgeusia to prevent weight loss and malnutrition (Evidence: Moderate 1).
  • Evaluate and adjust medications that may contribute to dysgeusia in elderly patients with multiple comorbidities (Evidence: Moderate 2).
  • Implement dietary modifications and nutritional support tailored to individual needs, especially in vulnerable populations (Evidence: Moderate 1).
