==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
* Strokes 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)
===Diagnosis===
Consideration of ruling out potential secondary causes such as cancer, DM, hypothyroidism, or oropharyngeal causes 
==Management==
Management should focus on treating the underlying cause, if one is identified.

==Disposition==
Outpatient ENT referral and workup
