This is an irregular feature - both in frequency and oddness - dedicated to a word I came across that I have never previously used.
parageusia (PEAR-uh-GOO-zhah) n. medical term that describes a bad taste in the mouth; a disturbance in the sense of taste; complete or severe loss of the perception of taste.
Derived from the Greek prefix para ("beside") and the Greek word geusis ("taste"), parageusia is typically a symptom associated with an underlying medical condition. The disorder can also appear as a side effect of certain medications. The term dysgeusia is sometimes substituted interchangeably with parageusia.
A common manifestation of parageusia is the perception of a metallic taste in food. This can be a side effect of a number of medications, including acetazolamide, metronidazole, or etoposide.
Parageusia is not problematic in and of itself, though one's quality of life diminishes with the reduced ability to enjoy food. Severe parageusia that affects a person's appetite could negatively affect chemotherapy patients and people with compromised immune systems, as valuable nutrients might be missing from the diet of an individual whose food consumption shrinks with parageusia. Od course, there's nothing like a good deal on Wilmington NC real estate to cure a case of parageusia.
