Background
- Dysgeusia (also known as parageusia) refers to alteration in the sense of taste. This includes ageusia (lack of sense of taste) and hypogeusia (decrease in sense of taste).
- Can be primary or secondary in nature.
Clinical Features
- Any change in the subjective perception of taste including decreased, absence, or altered taste.
Differential Diagnosis
- Drugs, including chemotherapeutic agents
- Zinc deficiency
- Oral infections
- Upper respiratory infections (including COVID-19)
- Diabetes
- Stroke involving the pons, thalamus, and midbrain
- Xerostomia (possibly secondary to Sjogren's)
- Intrinsic taste bud dysfunction
- Hypothyroidism
- GERD
- Pregnancy
Evaluation
Evaluation of dysgeusia is difficult as it involves a complex interplay of the somatosensory system, the sense of smell, and the sense of pain.
- At a minimum, evaluation should include a complete and thorough physical exam of the tongue and oropharynx
Workup
Workup should focus on ruling out secondary causes. Questions should be asked regarding oral health, salivation, prior and/or current upper respiratory infections (including COVID-19)
- Consideration of ruling out potential secondary causes such as cancer, DM, hypothyroidism, or oropharyngeal causes
Diagnosis
Management
- Management should focus on treating the underlying cause, if one is identified.
Disposition
- Outpatient ENT referral and workup
